Thinking about buying these motors in the swap. On my 32 fountain I need some type of mufflers. I will be removing the silent choice +emi exhaust . With 741 cam and 9.5 cr what options do i have with a dry exhaust to prevent revision? Using the stainless marine manifoilds on the engines and geting bravo pipes. How about using the gibson downturns after drilling a 1" hole above the water line ? or external?

As long as you use the Hp500 tail pipe with the turbolators you should be fine with the Gil's.

I have 2 sets of EMI, motors have stainless marine, hope to use either set that i can get a set of risers for later. Do TRS exhaust have more problems with. Revision with performnce cam?

The Hp500 tail pipes are taller and longer witch helps with the reversion don't see why if you copied a set for the stainless marine why that would work.

ok

I ordered 2 xr drives last night. By spring hope to have motors to match.
