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.

Magnaflow exhaust/banks turque tube headers 2004 GMC 2500 HD

Reviewed By Jody T (Montgomery, TX) Reviewed for a 2004 GMC Sierra —5/15/2012 9:36 PM

I had an exhaust shop install my my magnaflow system along with banks torque tube headers. The four inch tip has a tuff look. The sound is deep and makes my truck sound strong. I have not pulled a trailer yet. But on the hi-way I gained 1.5 MPH.
