wasn't really sure how they would sound with a 3.8L but I guess it is what it is its not some monster v8.But yes I Really do enjoy the deep sound, Ive ALWAYS loved the sound of FLOWMASTER.

Good deal for the price

Reviewed By Michael F (PUYALLUP, WA) —10/23/2016 5:05 PM

Made my car sound a hell of a lot better than stock! They aren't the sound I was exactly looking for, so soon i'm gonna replace them with some flowmasters. But both for a little over 60$ and it sounds a lot better than stock. good deal
