Flowmaster Super 10 Series Mufflers Reviews


Perfect muffler for my truck

Reviewed By brian e (Columbus, OH) Reviewed for a 2002 GMC Sierra —4/12/2015 5:09 AM

I had a 40 series flowmaster single in/out with stock tailpipe on my GMC 5.3, it sounded good at idle but disappeared at WOT when I really wanted to hear it, so I bought the super 10 to replace it, I dumped it right by the rear axle, this thing sounds amazing, exactly what I was looking for, I find myself flooring the gas peddle just to hear that amazing exhaust rumble. I couldn't be happier and if you are scared it will be too loud, don't be, it isn't super loud, but it is deep/aggressive.

Flowmaster Exhaust Systems Reviews


In the box

Reviewed By Herb M (GOUVERNEUR, NY) Reviewed for a 2002 GMC Sierra —9/21/2013 4:00 PM

The overall system is easy to install.The sound and throttle response is exactly what I was looking for.But, A few things left out of the box was nuts for 2 clamps and they don't give you new bolts to mount to the cat.I had to bend a section of pipe because it hit a cross member.After a trip to the hardware store for new bolts and nuts for the clamps I was good. The price I paid should of included a few more parts.
