I am curious on opinions in brand (sdp, profab etc) for one and the other thing, with whatever manufacture I choose, say for example I bought an sdp "race pipe" and further down the road I buy a bridge..do they have to be from the same manufacture? I'd like to know who I could go with to do that if possible, I'd like to go with a boost tube first on the stock bridge and eventually replace factory bridge. Thanks in advance!!!!
