Flowmaster Exhaust Systems Reviews

Great sound

Reviewed By Shayne R (SWANTON, OH) Reviewed for a 2004 GMC Sierra —1/28/2015 9:11 AM

I love the looks of this on my 04 GMC Sierra. Sounds great as well. Mostly easy to install minus shearing off the studs from the stock mounting point. Although flow masters kit pre planned that as they supplied new bolts for that reason.

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.
