I need help

'01 EFI 88B with S&S 510 gear cams, Screamin Eagle II exhaust & A/C. My question is.. Will a set of 2-1 pipes enhance or rob me of the performance of the cam upgrades. I been thinking that the 510s will add HP so the 2-1 should enhance my TQ. Am I thinking straight or flawed? I like the thought of equalizing the cylinders but do not want to f-up my new cam upgrade. Im thinking Big Radius 2-1. If this is not a good pipe, then what do I use. Performance first!!

Brutus01 is right, 99% of the time you get better numbers from a 2 into 1, I'm sure you can find the ones that throw the best numbers with a quick search on here.

That advantage of 2-1 pipes are usually in the 2k - 4K rpm range.

And they don't always make better overall numbers than a good set of 2-2's, just down low-mid.
