Customer Reviews

Overall a great product. Pretty easy for installation. My friend and myself did in in about 1 hour or so. The clamps only give me concern just because its a clamp and not welded, but hey go get 'em welded to feel good about it. (thats what I did) No exhaust leaks or anything like that, just welded them for my own personal self confidence. I enjoy them very much. 4.5-out of 5!

Got this installed last week along with Pacesetter Headers* (highly recommend.) It is hard what came from either but the exhaust system definatley helped. The sound is awesome, it has a low rumble to it, w/ the headers it sounds exactly like a V8. Some of my friends thought that I put an LS1 in it from the sound. The hp gain was noticable, also saved a a gallon or two of gas drving across Texas. The only bad thing is one of the bolt on parts is kind of low (Firebirds only have 4inches of clearance to begine with) but luckily it is in the middle of the car and it isnt toward the front. Like I said before, would strongly recommend doing this upgrade with Pacesetter headers at the same time. The HP gain was intense (shifting around .5-1 rpm later now.) Super satisfied with this product. Came with-in a couple days after I ordered it. The customer service from autopartswarehouse.com was very profressional. I called and asked them questions about the product and they answered them all the way and gave me a 15% discount on my order.
