I've been getting the funniest looks from people from this question, but I really could use some good advice. I have an EG hatch running a C5 that's being pumped out the stock DX exhaust. I'm looking for the highest flow OEM exhaust I can find, all I know of is the 92-95 Civic Si exhaust. I've tried the Del Sol Vtec exhaust and it's a ton larger but not even close to fitting (needs to be cut up to fit) as well as the coupe which needs a little work to fit. Does any Integra exhaust bolt up for example or am I limited to the SI. Everyone says the simple answer is aftermarket, but I need the stock look and sound, nothing else will work. Any idea's you guys have will be great, thanks!
