I am looking to put a full exhaust on my 2000 LS1 Camaro. I had the Loudmouth 2 on my v6 camaro but the interior noise was horrible. I tried searching to see if anyone mentions cabin noise on the PowerFlo. At cruise on a highway, with the PowerFlo, is the cabin noise incredibly loud?


If the cabin noise is going to be super loud, what do you recommend that has a nice throaty sound but not terrible interior noise? I don't want to have a super loud exhaust, just something that sounds good.

I am looking at this from TSP:

Hello, Power Flo owner here. Disclaimer: I still have stock manifolds and cats, so I can't attest as to what it will sound like with headers.

Interior noise isn't too bad, especially with the windows rolled up. The exhaust is noticeable, but you can still comfortably have a conversation with a passenger or listen to the radio. It does drone a bit around 2k rpm, but other then that it sounds great. The tone is deep but smooth with zero rasp. On the highway my tires make more noise then the exhaust while cruising.

Exterior noise is noticeable but not obnoxious. It's obvious the car is a V8 but doesn't bother my neighbors driving to work at 6:30am or risk getting a ticket driving past a cop.

I hope this helps. I haven't seen too many people on ls1tech using this exhaust but I'm happy with it overall.

Those mufflers with a catted y-pipe and headers should have a very deep tone without being very loud at all. I can't imagine there being much cabin noise with that setup
