Love the sound of my 40 series. I put it on my 99 Trans Am. Sounds great and turns heads. Love it.

Reviewed By John Y (Novi, MI) Reviewed for a 1968 Pontiac Firebird —8/15/2007 10:14 AM

These mufflers sound good outside of the car. They give the car a nice growl. I have a 1968 Firebird with a 400 engine. A little more resonance inside of the car than I expected. I am running 2 1/2" exhaust.

Reviewed By Dennis W (Salt Lake City, UT) Reviewed for a 2015 Dodge Charger —10/12/2016 7:09 PM

these mufflers have a very aggressive louvered core, so they were installed with open part facing away from the engine. just loud enough here inside [no drone] but when you get on it wow! And if I use paddle shifter at high rpm they have a wicked bark!!! But not obnochiss till you want them to be. don't be scared if you like a healthey exhaust sound these mufflers rock!
