I wanna swap an H22 into a 94 civic, but I'm wondering if i can buy the exhaust for the prelude engine or for the civic engine or if I have to have it cut to a custom length so it won't be too short or stick out a foot from the bumper. (J/k.) Any advice would be nice for those of you who have done the swap yourselves. What exahust did you use and how did you order it (custom or just out of a retail inventory). thanks!!
