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.

Flowmaster Original 40 Series Mufflers Reviews


Roaring sound

Reviewed By Osman T (Detroit, MI) Reviewed for a 2001 Chevy Monte Carlo —5/23/2017 9:52 PM

Bought and installed these original 40 series mufflers on my 2001 monte carlo. It makes a great roaring sound that's controlled as per the throttle response. I can take off with easy acceleration and it makes a noticeable sound (roar) I slam the pedal to the metal and it gets much louder which is exactly the type of sound how and when I wanted. No interior drone. So this was done on my stock everything v6 3.8L engine. Now i can imagine the sound from these mufflers onna v8
