Great power adder and looks improver. by Vroom Vroom, October 31, 2012

Overall Rating:

I purchased these to install along with a Heartthrob Deep Tone cat back exhaust system. I had been experiencing an exhaust leak and had been wanting to upgrade my exhaust system for a while before that. I had them professionally installed. The garage where I had them installed had to redo part of the down pipes because the flanges wouldnt meet up squarely which in the long term would lead to a new exhaust leak. Id really have given this a 5 star if they were truly bolt on and if the fasteners were stage 8 locking. As it is the washers where of the starred variety. These ceramic coated headers look great. In conjunction with the cat back exhaust system Ive noted a slight enhancement in performance (less downshifting going up hills and a very slight increase in gas mileage).
