I picked up some Flowmaster 50 Series Delta Flows from Summit Racing and I was looking on a GMC forum for trucks and found some people losing torque and gaining hp only at higher rpm's with the Flowmasters.

Which exhaust would provide better performance? Also...did Flowmaster really address the interior resonnance issue with these newer Delta series?

I'm sticking with the stock exhaust manifolds and I am considering a crossover pipe.

Thanks in advance.
