yeh, thats not too bad considering how expensive they can be. i would buy new if i had the cash.. and i cant really wait a month on shipping.
i probably should of said, any old 2nd hand exhaust. also need a muffler, but not half as bad as the expansion chamber.
at the moment i temporarily took the bolts off the header flange to lessen the restriction, so its just ridable at 40k's flat out no powerband.
