40 Series

Reviewed By Ian M (Sedgwick, KS) Reviewed for a 1999 Pontiac Firebird —7/10/2011 3:32 AM

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

Flowmaster 40 series Delta Flow

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.

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
