Exhaust ?

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?

If you are after every single individual hp then yes, otherwise don't worry about it. I got a 3" downpipe made ages ago. When I came to make the exhaust I could not make the 3" quiet enough so went with a 2.5" setup, very quiet.

Thanks for the responses. I think for now I will just do 2.5-3 reduction piece after the connection point so that it expands evenly. If I ever do go for big numbers I can alter that fairly easily.
