will 5th gen headers and exhuats work on a 4th genn h22. i could see th exhaust not workin but i dont see any reason why the headers wouldnt. i can deal with slight modification but welding sux and im not very good at it. also does anyone know where i casn find SMSP headers?

 

A 5th gen header will fit on a 4th gen with a slight modification in length.

You can contact SMSP for info on his header.

gonna be short or long? and any idea how much? also how bout a 5th gens exhaust system?

 

the 4th gen header is about 6 inches longer then the 5th gen base and about 2 inches longer then the sh.

I'm pretty sure the 5th gen exhaust is longer then the 4th gens. probably due to the header length diff and i believe the 5th gens were slighlty longer then 4th gens
