Im thinking a head a little about my mini, i dont want it too loud, maybe that is because im getting a little older ! But, ive seen a cooper spi system, its got two boxes, both look straight threw. Id imagine its about the noise level im after, but the engine for my car is a 1293, its got a cam init, and a very well ported head. Im not sure of the power but id be thinking of 80-90 bhp.
Will that exhaust system strangle the engine, or is there a better one for it? This one ive seen is second hand and not a lot of money, so i was thinking of buying in advance.
thanks
