They got them to me very fast and witb no problems what so ever. Did the installation my self and it was super easy to do. They are built exactly right for the vehical you choose. It makes the sound much deeper and more gutsy, plus the added MPG is great.

Ownership: 1 month - 1 year
Performance and looks is great. The package comes with everything you will need. However, the X pipe fitment leaves something to be desired. The X pipe fits in such a way that it dips or hangs lower than the rest of the exhaust. My local exhaust shop tried flipping it every way concievable and at best it hangs. Since my car is lowered it scrubs on everything. Looks like I will toss it out and build a custom X pipe.

ARH Camaro V6 LongTube Headers SHORT SYSTEM with Cats; 2010-2011
5 Stars Awesome bolt on!, Date: 2/25/2010

By: mrray13
Ownership: 1 day - 1 week
Wow, the quality, fit and finish of these headers is outstanding! I had JBA shorties on the car and had a best dyno of 253 rwhp and 239lb-ft of torque,+5rwhp and +8rwtq over baseline. The ARH headers/cats bolt on was another 10rwhp and 10lb-ft of torque! That's 15 plus over baseline in hp and 18 plus in torque! Not too bad, not too bad at all! These are quality parts by quality people! These are easier to install then the shorties too!
