Rating Summary #79,606

Hey thanks a lot! I've about got all the pieces to put it all together. Its going in a 2001 b4c car. I have taken the motor down to the bare block, put new cam, rod, and main bearings in it and replaced just about everything that could be replaced. The heads are just 241 castings but have been milled, ported and polished. While im at it I am doing away with cats and egr and putting slp long tubes on. Do you have a recommendation on y pipe or true duals and a ballpark estimate on hp when i dyno it? Thanks again! Brennan
