Nice rumble

Reviewed By James M (Collegeville, PA) Reviewed for a 2004 Porsche Cayenne —6/29/2007 4:09 AM

Installing it was a breeze. I like the rumble of the Delta 40, however, I wish it was a little louder.

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.
