Best Price & Great Quality

Reviewed By Charles S (Bozeman, MT) Reviewed for a 2003 Hummer H2 —1/18/2018 8:12 PM

Bought the non-coated version for 03 Hummer H2. No problems with heat plus I personally like the rainbow discoloration effect. Perfect fitment. Super easy install if you're mechanically inclined. Noticeable increase in midrange pull but not drastic. Exhaust note is slightly crisper but not louder. Very good quality

2008 Hummer H2 - Very disappointed

Reviewed By Jose E (ORANGE PARK, FL) Reviewed for a 2008 Hummer H2 —1/2/2018 2:41 PM

VERY DISAPPOINTED!!! I was looking to purchase either the Borla or the Magnaflow. Wish I would have gone with MagnaFlow. Borla said "distinctive Borla Sound of Power." NOT TRUE. This exhaust makes MINIMAL sound while idling and only purrs when you are on the pedal. For the money you are going to pay, consider MagnaFlow or FlowMaster, will sound better with a less expensive price tag.
