DynoMax 39522 Ultra Flo Evolution Competition Cat-Back Exhaust in Stainless Steel for 12-18 Jeep Wrangler Unlimited JK 4 Door with 3.6L

Rumble rumble rigg sounds good!

This is the perfect JK exhaust in my opinion. It has what I like to call, "the Jeep sound". I feel the exhaust tone of this muffler perfectly fits what a Jeep should sound like. I looked a long time for an exhaust system that gave great sound without being too loud or annoying. There is a bit of volume on cold start up, but it settles right down to a quiet purr. When on the throttle or pulling a grade there is a bit of drone, but it is not overwhelming. I appreciate being able to hear what the engine is doing while driving. I didn't realize I might be lugging the engine sometime but now I know exactly the RPM just by listening. I highly recommend this to anyone looking for an excellent replacement to the stock muffler system.

This is a ver basic system, the removal was a process... The Dynomax exhaust is a lot louder than the YouTube/customer videos show. The muffler actually rubs on the frame with the stock hangers, also the factory puts stickers on some o the components, no matter what I did, the residue would not come off and I got a burning off smell for a couple days, gone now.
