Primaries yes

But you also have secondaries (not hooked up to any sensors) in the catback section. If you know you're going to go catless, I would keep secondaries. If you don't want to bother with catless (needing a tune, dealing with emissions), then chopping off the secondaries is fine.

For a street car I'd do the latter, and do a single merge like I linked above or just get the SS exhaust that does the same. For bump in "power", I'd switch up the final drive to a 3.73 auto (assuming you got manual).
