The plan was for a semi quiet free flowing 3' exhaust. Basically high flow cat, 12' glass pack style muffler and large straight through muffler. I come to find my current downpipe is 2.5' and at the connection point it expands to a 3' pipe back.
would this be considered a bottleneck as its only a few inches further down the exhaust path before it expands to a full 3' diameter?
