    S52 Exhaust Options

    Hey, I know this has probably been discussed many times, but I would like some more insight.
    I'm planning out my S52 swap, wondering if 1.75" dual pipe exhaust is enough. I'm looking for an exhaust that is not too loud, as this will be my DD for half the year when there's no snow on the ground. I ask as I have an Ireland Engineering catback for my M20, which has an ID of 1.65", and the ID of the OEM S52 exhaust manifolds is not that much bigger. I figure I'd have to do some sort of custom option for mid section anyways, so maybe I could adapt the m20 downpipe?
    I may upgrade in the future, but it would be nice to reuse parts and save some on the budget. I figure when that happens, I'll replace everything, including the headers.

      Thanks. I saw that, looks like some builds are using the modified e30 exhaust. Definitely curious to know if the engine feels restricted. Might have to just try it out!
