Test Pipes/Headers

[Eclipseracer1485]

I just installed a JWT popcharger and HKS Tru dual exhaust. I have been researching information on test pipes and headers but havent found much. From what I have heard the stock headers are pretty decent and you will not see much gain by switching to aftermarket ones plus since I plan on TT it prolly doesnt make any sense buying headers since the turbo exhaust manifolds will replace them anyways. As far as the test pipes go though does anybody recommend one over the other?
