Flomasters on a v6 Challenger ralley redline

Reviewed By Gary O (EVANS, GA) Reviewed for a 2004 GMC Envoy —7/31/2014 5:32 AM

my new exhaust came in a box, i lined up the parts as directed on the floor of my garage, i backed up the car on some ramps, removed the old exhaust, just as the instructions said, and then proceded to put the new flowmaster's went actually very well, it would have been a little helpful if the instructions would have mentioned not to fit the pieces 'all the way on' to begin with, since you will need to slide them forward and backward to get all pieces to go together with the clamps covering, or if the parts were just a little bit longer so as to have a more visible part to part fit, and if the instruction went into the alignment process a little deeper...i don't have problems reading directions and following i would appreciate more text about the process...but once finished, i was very pleased...the car roared on first startup...very nice, not too loud, not to poppy...very smooth and mellow...i don't drive that hard, but am proud to have the challenger/flowmaster/k&n intake car...i believe that i am making just a little more horsepower than my 68 Chevelle ss396 i had in high school back in 69...

Gibson Exhaust Systems Reviews

Beautiful exhaust note and incredible increase in HP

Reviewed By Joe G (Wilmington, CA) Reviewed for a 2003 GMC Envoy —6/20/2014 10:20 AM

Great product, super fast delivery and exactly as promised. Made my 11 year old GMC Envoy come back to life. A little pricey but no quarrels with the quality. Great transaction.
