2.5" exhaust with my 310 whp setup… I tried a 3" exhaust and there were zero gains…
What size pulley was that?
I’m going to try a 2.7" pulley on the stock internals - if the engine goes pop, at least then i will have found the limit of the components.
2.5" with a built engine… You do know when an engine goes pop more than one thing gets screwed up… It’s a lot cheaper to build an engine than to repair it…
This was back in 07 with a 2.5" exhaust with a Burns 3" stainless muff…
