Is the exhaust going to serve the 305 as well as the LS engine? Factory Monte SS mufflers and tail pipes are only 2" so I would not go too big for a stock 305 exhaust and IMO I would not go larger than 2-1/2" for that.
Needing ideas

more than likely not, i may be a while before the LS swap. 2.5 is good with me though, that is why i am asking, i am not so familiar with how to make these older motors sound good. I have had plenty of header and glasspacks/turbo muffler projects, but i am too old now, i want rumble, like the newer vehicles with out being annoying
I'm running Pypes X-pipe 2.5 inch stainless system with Race Pro's. Love the sound, mellow at low speeds and wakes up with a heavy foot. The kit with rear exit pipes seem to have fitment issues with the tailpipes however I had no issues with the side exit kit. Head pipes are sold seperately for various engines if your using manifolds.
Also, I used stainless stepped band clamps instead of the U clamps that come with the kit. Makes it way easier if you need to take it apart later.
Yeah my buddy and I did that with a 73 impala sport with a 468 BBC with race mufflers you couldn't hear your self think go behind rear wheels
The bigger the pipe diameter, the louder it will be. I would stick with exhaust manifolds, not headers. Dynomax mufflers sound good.
