Flowmaster Exhaust Systems Reviews


Not bad

Reviewed By Cody H (SODDY DAISY, TN) Reviewed for a 2004 GMC Sierra —10/21/2014 7:08 PM

Glad i went with the 40 series version instead of the 50. Still not as loud as i thought it would be. Was boxed up well. Instalation was the worst part. Didn't exactly line up with the factory hangers perfect and had to put small hose clamps to keep the rubber hanger on the metal arm. No major difference in power or mpg. Main reason i purchased was for the flowmaster sound. It doesn't disappoint there. I would recommend having the exhaust welded after everything settles and you get it in place.

Nice tuner.

Reviewed By Cody H (SODDY DAISY, TN) Reviewed for a 2004 GMC Sierra —10/9/2014 8:48 PM

Bought this tuner to go along with my full exhaust and intake. Made a very noticeable difference in power and the way the truck shifts. No mpg improvement that I've noticed, but not why I bought it. Would definitely recommend on GM trucks. Also allowing for custom tune is nice as well.

Better than expected. Easy to install after going through instructions taking very little time. Love how the bows roll up with the cover so out of the way.Dressed my truck up nicely and is a great cover for the money.
