Hey guys I am new to this forum and Preludes as well. So here goes my little story/question. I had bought a 01 Prelude type SH a while ago which had the stock usdm motor (h22a4). It had taken a shit and I had gotten swapped an h23a (blue top). Trying to get bolt-ons or parts in general. When looking for parts how do I know which one to get exactly? When asked, "Is it the base model or type SH?" I obviously say type SH since that's the actual model of the car. When looking for bolt-ons (exhaust, headers etc) how do I know which one to get? Base or type SH? I'm asking here because I put type SH in which car to look for, for the parts and it always refers to the h22. I was looking for an exhaust system and it said this, "SH model has a longer length header. Our mid-pipe will be too long to fit on the SH, so you will need to cut and remove about 4 inches of pipe from our resonator mid-pipe to fit. Cut out 4 inches and re-weld the flange. Bends are the same" How or when do I ask/look for the right part(s). Sorry if this sounds confusing... Please help! Thank you again for those to help out and reply to this.
