Hello horse power!

Reviewed By Erik R (READING, PA) Reviewed for a 2008 Pontiac G8 —8/6/2013 12:44 PM

I was very pleased with these headers in conjunction with the 3" Magnaflow exhaust I have on my vehicle. The installation was quicker than expected and after a quick tune and dyno, I saw increases of 35-40 HP above the original dyno!!

G8 Doug Thorley Review

Reviewed By Zachary W (Herndon, VA) Reviewed for a 2008 Pontiac G8 —6/17/2009 8:53 PM

Very nice headers, especially for the price! AutoAnything has fast shipping. Doug Thorley are comparable to more expensive headers from ARH and Kooks. Excellent mid range torque gains. Gained 30whp/wtq on the dyno, my car dynoed higher then cars with Kooks and similar mods. You will need to dyno tune your vehicle to the headers to take full advantage of the power they can produce. A hand held tuner or canned tune won't cut it.
