Quote: I did 2.375" on my Coronet years ago and would never do it again . I don't care what some calculator says , it has to fit in car.A 2.25" would work just as good and it is way easier to buy and find in stainless or carbon . The B1 is only a 1.78" valve so its not fooling anybody by putting a macho pipe in it.
This is good advice ^^^^^. I would also advise against anything bigger than a 4" collector. J.Rob
