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

I got these for a great deal!They sound perfect at idle and downshifting,with a nice deep rubmble.But when you hit the gas,watch out!I couldn't be more happy with these mufflers.Definitely worth getting-2016 Dodge Challenger SXT V6 3.6L
