i know that their main outlet for distribution is promotion distribution(wholesale only, but one of the biggest suppliers of aftermarket parts). as far as power gains i think somone posted a dyno. look at the third post and follow the link.

 

top fuel is a great tuning house...i have some of their products and they are great design and build

 

sorry guys, my cousin just picked up a g35, so i gave it to him. let me know if you guys want to buy one, i can still get more. obviously not at $150 though.

 

how much?
and any sound clip?
thanks
