sure u can sell them. u can buy them custom. all it is is pipe from the header bro. go to home depot and u can buy pipe, just have someone weld bolts and make it fit. and off u go. a decent alternative to straight pipes is to punch ur cat and put a very high flow muffler on there. gives a mean growl and if ur lucky u can pass undetected in cali. i live in vegas and im attempting to be daring, i want to flip my headers and have the exhaust come out from my hood. HOT ROD BMW!!!wait... your can sell straight pipes? I thought straight pipe was unbolting the muffler.
hey FOX lemme know how that supercharger kit works. i wanna turbo my 325i but i want something i can just slap on there and burn rubber with. i have the m20b2.5 5 speed. just so u know lemme know about pricing...thankx :driving :bimmer :bjLoL i dont really think I like it either. I mean it would be sweet on a 24/7 track car but its just way to loud to drive around. I have to crank my stereo now to even listen. But yea it does sound pretty mean, However im thinking of putting a superdyne supercharger on my car. I think i can build a kit for around 1 grand. If i do ill keep the straight pipes on instead of selling them.
