Granted out of the 3 cars I’ve tried this on only 1 was a turbo, it by far sounded best on NA engines. Makes straight pipe volume but doesn’t sound like straight pipe raspy garbage. Very rumbly and hilarious, highly recommend

2014 chevy silverado v8 all i did was have this muffler replace the stock one and delete the resonator still have all 3 cats, loud on cold start but driving is a very pleasant low rumble

At the time this muffler was only $44 dollars, it seems like the price is increasing but at the price I bought it at its well worth it. Had a great deep idle sound for my 2008 Chrysler 300 LX with the 2.7l V6. There was definitely a lot of drone at around 1.75k-2.8k rpm’s and it was quiet noticeable but, I ignored it. Some of my passengers were also annoyed after a while but, I guess it comes with the territory. I totaled that car anyway so, I hope the junkyard scavenger enjoys this muffler too

This is the best muffler I have had on my truck so far, (97 ram 1500). A friend of mine I drove by said it sounds like a Harley. Drone in cab actually is not terrible and if all windows are up cruising 60mph you hardly know it’s there

I put this on a Ford escort lx, and let me tell you, most people that heard my car asked “what’s under the hood”? IF this can make a ford escort lx sound good, it definitely will make your car sound good too!
