i'm in the process of swapping out a d16 for my newly acquired h22a1 with obd1. what kind of header / exh manifold should i use? will a prelude header bolt up to my cat? or will a prelude header with cat bolt up to my del sol's catback system? can i just use the entire wiring harness from the 'lude in the sol since they are both obd1?

 

i beleive that your flang from the down pipe to the exaust needs to be rotated a little bit to fit. not 100% sure tho

 

your dealing with a hybrid, so im not sure about pipeing. RMF, DTR, SMSP, HyTech, AN-R (no specific order) all make really nice and dyno proven headers. Bolt up the header your going to use with the cat, then have a muffler shop fill in whats between you ehuast can and your cat.

 

i got a full HKS on my hatchlude sounds great, but fabracation is need becuse it is a hybride like EK9-Stealth stated. I am now possative that the flang need to be rotated to fit the down pipe. take it to a Lous exhaust, or other shop
