Frequently Asked Questions

What's the best exhaust for a Challenger 5.7 Hemi?

For the 5.7 Hemi Challenger, a cat-back system with chambered mufflers gives the best balance of that deep Mopar V8 rumble with daily drivability. A mid-muffler delete with quality rear mufflers is also popular. Avoid straight-through glasspacks if you daily drive - the 5.7 can get raspy. Chambered designs bring out the deep Hemi tone.

Do Challenger and Charger exhaust systems interchange?

Many mid-pipe and muffler components are identical between Challenger and Charger since they share the same platform. However, the rear section differs due to different exit points - Challenger exits at the rear corners, Charger behind the rear wheels. Most manufacturers make model-specific kits to ensure proper fitment and appearance.

Will a Hellcat benefit from an exhaust upgrade?

Yes, even though the Hellcat is already loud from the factory. The stock exhaust is still somewhat restrictive to meet noise standards. A cat-back system can add 15-25 horsepower by reducing backpressure on the supercharger. The power gains are more noticeable than on naturally aspirated Hemis due to the forced induction.

Is mid-muffler delete a good option for Challenger?

Mid-muffler delete is one of the most popular Challenger mods for dramatic sound change. It removes the factory resonator/mid-muffler, opening up the Hemi growl significantly. It can cause some drone and rasp, though - pairing it with quality rear mufflers helps. For best results, combine with the right muffler choice rather than going resonator delete too.

What exhaust size should I run on my Challenger?

For 5.7 Hemi, 2.5-inch dual exhaust flows well without being oversized. For 6.4 392, 2.5-3 inch works great. For Hellcat and Redeye, 3-inch is recommended to handle the supercharged power. Larger isn't always better - properly sized exhaust maintains exhaust velocity for good throttle response.
