Quality engineered part

Reviewed By Cole H (Chicago, IL) Reviewed for a 2007 Hummer H3 —9/2/2015 3:53 AM

It's pretty simple. Rattle trap exhaust is now smooth reving, with zero loss of power after updated dyno. Only issue would be weight, pretty heavy part to add in. One of the ideas behind this Hummer H3 was to reduce weight and all lite weight exhaust just got killed back to stock weight with this installed.

Sounds great!

Reviewed By Lee M (CORTLAND, NY) Reviewed for a 2008 Hummer H3 —11/7/2012 12:06 PM

I only have an inline 5 cylinder egine so I wanted good performance,sound and better fuel economy. Thats what I got with the super 10. It added a better sound and tone to the inline 5.

It's quiet, but robs power

Reviewed By Jesse A (NORTON, VA) Reviewed for a 2004 GMC Sierra —7/11/2019 6:36 AM

. Certainly made the exhaust quiet, the engine makes most the noise now. Doesn't really have a "tone" over stock muffler. About the same as I can tell. I had the stock 3.5" with a test pipe on it and edge juice. You touch the throttle and it was taking off. This muffler is HUGELY restrictive compared to a test pipe or even straight through 4". Really have to step on it to get it to move now. To do again, I'd buy a 4" system w/muffler and be done with it.
