well , I have tried expensive ones and the one I went back too, did the best on the bottom and top end combined, the hpi savage X L pipe and header, for around 20 or 30 dollars. if you have the single big bore shocks the X L header will work. it is a half round header, less restrictive. I love that set up! if not just use the factory header you have with just the X L muffler

I also removed a shim from my hpi f4.6 head button for more power, I run 3 shims, hpi puts in 4 to 5. with those 2 upgrades, header and pipe and 3 shim set up my truck rips.
