2015 Denali 6.2

Reviewed By Bill B (New Hartford, NY) Reviewed for a 2015 GMC Sierra —11/17/2016 3:59 AM

These just added the snap I was looking for from the accelerator you can here and feel the difference in the motor. I partnered this with a K&N 77 series intake and Borla touring exhaust and it brought the 6.2 alive. Better power great sound and picked up 1.5 mpg.

doug thorley shortys for 06 toyota tundra 4.7

Reviewed By Josh H (Jonesboro, AR) Reviewed for a 2002 GMC Yukon —6/27/2010 12:20 PM

If it wont kill you to dish out the money i would recommend these headers. I gained a consistent 2 mpg better, accelleration seemed to be smoothed out, definatly winds through the rpms quicker now, didnt lug at lower rpms like it used too. Didnt make exhaust very much louder at all that i noticed as i already had a custom cat back exhaust...just changed the exhaust note, a little more aggressive...seems that you can hear individual cylinders firing....i feel more low end torque for sure......I LOVE THESE HEADERS!!

Flowmaster Scavenger Series Elite Headers Reviews


the lazy engine is gone!

Reviewed By Javier C (Mcallen, TX) Reviewed for a 2007 Chrysler 300 —11/14/2016 8:34 AM

Headers paired up with Legmaker True CAI V2 and 87mm throttle body gave my engine a throatier, deeper sound. The engine doesn't feel lazy anymore and it has better throttle response. Noticeable gains in HP and torque. Diablo predator added a couple of weeks later and a custom tune and it feels like a new engine. Cannot wait to install a new exhaust and cam.
