Installed these on my Pontiac G8. The exterior sound is a nice rumble. not too loud, not too quiet.The interior noise "drone" is rather noticable but not too terrible and has a little vibration to it. Again, not terrible. Nothing a little sound dampener cant fix.

Sounds amazing!!!

Reviewed By John S (MYRTLE BEACH, SC) Reviewed for a 2013 Toyota 4Runner —5/11/2018 12:09 PM

I used a local muffler shop to install this, they did a good job though. My gas mileage has increased a good bit as well had an incremental increase in power and torque, it's hard, really, to gauge these without a dyno. It sounds great, everyone loves it. Most say it "sounds nothing like a 4Runner". My only complaint is the baffle within the muffler as this is a single entrance and exit muffler but the muffle itself has a dual chamber construction inside. Noise will be fixed with insulation.
