doing the works ported heads, 37Gcams, punch to 95" etc. What is the best exhaust to go with for optimum preformance?

 

FatCat will give you great torque that starts early and stays pretty high (flat) all the way arcoss the RPM range.

A SuperTrapp will probably give you higher "peak" numbers and more tune-ability, but will not have as much down low.

Of the pipes I have experience with, they would be on the top of my list.

 

For the all-around best 2-1................Fatcat 2-1. Best sound, best quality, and best performance.

Do a search. There's tons of info.

 

I've researched this subject to death and then some. As Phil & Steve have said, Fatcats. Mine will be arriving this week.

 

FatCat!

I'm liking the Rineharts by Bub. Are they any good??

 

Another vote for SuperTrapp!

 

If you like a purple tip, then you'll like the Rinehart.
