Im installing b17a in an 89' base model hb, I have access to an oem exhaust manifold and downpipe from a 99' jdm civic typeR, it is 4-2-1 and downpipe ends in 2.25". Will this fit my b17, also will it fit installed thus in an 89' hb? And if so, what should I do concerning the rest of the system after the downpipe, and what if any would be the benefits of using this over the stock b17 setup?
Thanks
