OK this is a question about my exhaust for ludeboom or anyone else who has some technical know-how. I have stated b4 that I plan on swapping an H22a1 or H22 some time this summer(to replace my H23.) In the mean time is there any problem put on a new cat-back exhaust system that will bolt directly to either of the aforementioned swaps and my current H23? I don't think this would be a problem, but I thought I should ask before I start looking. Thanks
