The Indian Challenger runs the liquid-cooled PowerPlus 108 V-twin, and while it makes serious torque from the factory, the stock exhaust keeps it quiet and a little restricted. The right slip-on or full system wakes up that engine, adds a deeper bark off idle, and trims weight off the back of the bike. The trouble is that “exhaust for a bagger” covers everything from a quiet touring muffler to a wide-open race can, so picking the wrong one means buyer’s remorse on day one.
We pulled together the seven exhaust options that Challenger and Challenger Limited owners actually buy, then ranked them by sound character, fitment, build quality, and how well they pair with a tuner. Whether you want a mellow rumble for long highway days or a loud, aggressive note for around town, there is a setup here that fits.

1. Vance & Hines Eliminator 400 Slip-On Mufflers: Best Overall
The Eliminator 400 is our top pick because it nails the balance most Challenger owners are after. The 4-inch billet body gives the bagger a meaty, planted look, and the tone lands in that sweet spot where it is unmistakably louder and deeper than stock but never turns into a headache on a 300-mile day. Off the line it has a satisfying bark, and at a steady 75 mph it settles into a low rumble instead of the cabin-filling drone that plagues cheaper cans.
Installation is genuinely a driveway job, sliding onto the factory head pipe with the supplied clamps in well under an hour. The honest weakness is that this slip-on, like almost any on the PowerPlus, really wants a fueling tweak to perform at its best. Run it on the stock map and you may feel a faint flat spot in the low midrange, so budget for a tuner or a dealer flash to get the full benefit. Sort the fueling and this is as good as a slip-on gets on this bike.
- Large 4-inch body with CNC-machined billet end caps for a clean bagger look
- Deep, full-bodied tone that stays civil at cruise and barks under throttle
- Direct bolt-on fit to the Challenger header with no extra brackets needed
Pros: Strong low and midrange sound without an obnoxious drone on the highway; Premium machined end caps that look far better than stamped stock caps; Easy reversible install that pairs cleanly with a Fuelpak or factory tune
Cons: Best results really need a fueling adjustment to avoid a lean stumble; Chrome version shows heat discoloration near the inlet over time
2. Rinehart Racing 4-inch Slip-On Mufflers: Best Sound
If sound is your number one priority, Rinehart is the name that comes up over and over in Challenger circles, and for good reason. These 4-inch slip-ons produce a thick, throaty rumble at idle that turns into a genuine roar when you roll the throttle on. The character is more old-school muscle than raspy sport, which suits the heavy bagger perfectly. With the baffles installed it stays just on the right side of tolerable for daily riding, and that flexibility is a big part of the appeal.
The catch is exactly that flexibility. Pull the baffles to chase the full Rinehart roar and the bike gets seriously loud, loud enough that long trips can become fatiguing and your neighbors will know every time you start up. The cans are also on the heavier side, which you will notice when lifting them during install. For riders who put sound at the very top of the list and ride mostly around town, that trade is easy to accept.
- Signature Rinehart deep rumble that bagger riders chase
- Removable baffles let you tune volume between street and louder settings
- Heavy-gauge construction with a thick, durable finish
Pros: Arguably the richest, deepest tone of any slip-on on this list; Baffle options give you real control over how loud the bike gets; Looks and feels like a true premium American-made part
Cons: With baffles out it gets loud enough to annoy neighbors and bother some riders; Heavier than some lightweight competitor cans
3. Vance & Hines Hi-Output RR 2-into-1 Full System: Best Full System
When you want the most from the PowerPlus 108, a full 2-into-1 like the Hi-Output RR is the answer. Replacing the entire stock pipe instead of just the mufflers removes the biggest restrictions in the system, and the merge collector is designed to build midrange torque exactly where a heavy bagger uses it. Paired with a proper tune, this is the setup that delivers a genuine, butt-dyno-obvious jump in pull rather than just a sound change.
That performance comes with strings attached. A full system is not a bolt-and-ride part. You must run a tuner to remap the fueling, or the bike will run poorly and you risk a lean condition that no rider wants on a liquid-cooled engine. The install also takes longer and is a bit more fiddly than sliding on a slip-on. If you are committed to chasing power and willing to do the tuning homework, nothing else here matches it.
- Complete header and muffler system replacing the restrictive stock pipe
- 2-into-1 merge collector built to boost midrange torque
- Stainless steel construction with a high-flow design
Pros: Biggest real power gain potential of any option here when tuned; Aggressive, focused exhaust note and a noticeable weight savings; Frees up the engine for a stronger midrange punch out of corners
Cons: Requires a tuner to run correctly, not optional on a full system; More involved install than a simple slip-on swap
4. Bassani Road Rage 2-into-1 Exhaust: Best for Power
Bassani has a long history of building exhausts that actually move the dyno needle, and the Road Rage carries that into Challenger territory. The stepped header design is the headline feature, tuned to pull hard through the midrange and top, and owners chasing maximum output rate it among the strongest options for this engine. The megaphone muffler gives it a sharp, race-bred snarl that leaves no doubt about its intent.
This system is unapologetically aggressive, and that is the main thing to weigh before buying. It is loud, noticeably louder than most slip-ons, which is great around town and tiring on a long interstate slog. Depending on your bike and how you load it, the routing can also nibble at ground clearance a touch. If your goal is grunt and attitude over quiet comfort, the Bassani delivers in a way few others do, provided you back it with a tune.
- Stepped head pipe engineered for strong torque and horsepower gains
- Megaphone muffler with an aggressive, race-inspired tone
- Available in chrome and black ceramic finishes
Pros: Proven torque-focused design with a reputation for real dyno gains; Loud, mean exhaust note that matches the system's intent; Ceramic black finish handles heat well and resists bluing
Cons: Very loud, this is not a quiet touring system; Ground clearance can tighten slightly depending on fitment
5. Two Brothers Racing Comp-S 2-into-1 Exhaust: Best Lightweight
The Comp-S brings a more sport-minded approach to the Challenger, and the headline is weight. Pulling the bulky stock system and bolting on this compact 2-into-1 takes real heft off the back of the bike, which you feel in low-speed handling and just lifting the machine off the sidestand. The carbon fiber end cap gives it a modern, performance look that stands apart from the chrome-and-rumble crowd, and the tone is crisp and clean rather than booming.
That crispness is also the honest caveat. The Comp-S leans toward a sharper, sportier note, so riders who specifically want that deep, lazy V-twin thump may find it a touch too refined for their taste. The carbon cap also rewards a little care to keep it from looking dull. If you prioritize shedding weight and a tidy rear end with a clean sound, this is the standout choice in the group.
- Lightweight full system with a carbon fiber end cap
- Compact muffler that tightens up the rear profile of the bagger
- High-flow design aimed at both sound and modest power gains
Pros: Noticeable weight reduction over the heavy stock pipe; Modern, sporty look thanks to the carbon end cap; Sharp, crisp exhaust note with a clean tone
Cons: Sportier note may not suit riders who want a deep classic rumble; Carbon cap needs care to keep it looking clean
6. Freedom Performance Combat 4-inch Slip-On Mufflers: Best Value
Freedom Performance does not get the same marquee attention as some rivals, but the Combat slip-ons quietly punch well above their weight. You get a genuine 4-inch body with machined billet end caps that look custom, plus a deep and satisfying tone that many owners say rivals cans they expected to outperform it. For a rider who wants a real upgrade in sound and looks without paying for the biggest name on the box, this is a smart pick.
The honest trade is mostly about brand recognition rather than the product itself. Freedom simply is not as widely discussed in forums, so you see fewer install threads and less hype, which can make some buyers hesitate. Like every slip-on on the PowerPlus, it also gives its best with a small fueling adjustment. Look past the badge and the Combat is a very sensible upgrades on this list for the rider who wants quality without the premium tax.
- 4-inch slip-on with machined billet end caps for a custom look
- Strong, deep tone that punches above its segment
- Straightforward bolt-on install on the stock header
Pros: Excellent sound and finish quality for what you get; Billet caps give a high-end appearance at a sensible level; Simple, reversible install with included hardware
Cons: Brand name carries less prestige than the bigger players; Still benefits from a fueling tweak for best results
7. Vance & Hines Oversized 450 Slip-On Mufflers: Best Big-Bore Look
For riders who want their Challenger to look as big as it sounds, the Oversized 450 makes a statement. The 4.5-inch body is noticeably larger than the standard 4-inch cans elsewhere on this list, filling out the rear of the bagger with a chunky, custom-show stance. The extra volume inside feeds a deep, full tone that pairs naturally with the bigger muffler, so it backs up the visual drama with real sound.
That oversized look is exactly what makes it a love-it-or-leave-it choice. On the right bike it looks fantastic, but on a more classically styled setup the big cans can look out of proportion, so it pays to picture them on your specific machine first. They also add a bit more bulk and weight than slimmer options. If the fat, oversized aesthetic is what you are after, these deliver it with the build quality the brand is known for.
- Large 4.5-inch body for a bold, oversized bagger stance
- Deep, full tone that matches the big visual presence
- Billet end caps and a durable chrome or black finish
Pros: Massive visual upgrade that fills out the rear of the bike; Rich, deep sound that suits the larger muffler volume; Direct slip-on fit with quality machined caps
Cons: Oversized body is a polarizing look that does not suit every bike; Adds a little more visual bulk and weight than a 4-inch can
Frequently Asked Questions
Do I need a tuner after installing an exhaust on my Indian Challenger?
For slip-on mufflers you can often ride without a tune, but you will get the best performance and avoid a lean stumble by adding a fueling adjustment such as a Fuelpak or a dealer flash. For a full 2-into-1 system, a tuner is not optional. The full system changes airflow enough that running it on the stock map can cause poor running and a lean condition, which you never want on the liquid-cooled PowerPlus 108. Budget for tuning as part of any full-system purchase.
Will a slip-on or a full system give me more power on the Challenger?
A full 2-into-1 system gives the larger real power gain because it replaces the restrictive stock head pipe, not just the mufflers, and the merge collector is designed to build midrange torque. Slip-ons mainly change sound and shed a little weight, with only modest power changes even when tuned. If maximum performance is your goal, choose a full system like the Vance and Hines Hi-Output RR or the Bassani Road Rage and pair it with a tune. If sound and looks matter most, a quality slip-on is plenty.
How loud will my Challenger be with an aftermarket exhaust?
It depends heavily on the system and the baffle setup. Slip-ons with baffles installed, like the Vance and Hines Eliminator 400, stay deep but civil enough for long rides. Pull the baffles or run a megaphone full system like the Bassani and the bike gets seriously loud, which is fun around town but tiring on the highway. Many cans, such as the Rinehart, offer removable baffles so you can dial volume up or down. Decide how you ride before you commit, because loud is hard to undo on a long trip.
Are these exhausts a direct bolt-on fit for the Indian Challenger?
The slip-on mufflers on this list are designed as direct bolt-ons to the factory Challenger head pipe and include the clamps and hardware needed, so most riders complete the swap in under an hour in the driveway. Full systems take more time because you are removing and replacing the head pipe as well, but they are still designed to fit the Challenger and Challenger Limited without custom fabrication. Always confirm the listing matches your exact model year before ordering, since fitment notes can vary.
Will an aftermarket exhaust void my Indian Challenger warranty?
Installing an exhaust does not automatically void your entire warranty, but a dealer can deny a specific claim if they show the part caused the failure, for example a lean-related engine issue from skipping the tune. To protect yourself, use a quality system, run the proper fueling adjustment, and keep your records. Many riders run aftermarket exhausts with no warranty trouble at all. If you are concerned, talk to your dealer about how they handle tuned bikes before you buy and install.
Our Verdict
For most Indian Challenger riders, the Vance and Hines Eliminator 400 is our top pick because it blends a deep, civilized sound, premium billet looks, and an easy bolt-on install that suits everything from town runs to long highway days. If your priority is the richest possible exhaust note, the Rinehart Racing 4-inch slip-ons are our runner up, delivering that signature thick rumble with baffles you can tune to taste. Riders chasing maximum power should step up to a full 2-into-1 like the Hi-Output RR and pair it with a tune, but for the best all-around upgrade, the Eliminator 400 is hard to beat.
