Best headers for a 5.3?
 

Ive been thinking of getting a set of headers to go with my new PCM and Ram Air intake, but i do not know which company to go with. I want the best bang for the buck, any help would be appreciated. Also if there is another mod that would give me more performance or would compliment a new Nelson PCM and Ram air i would love to hear your opinions, thanks guys

ASM's or The other guys are about 750, Lapoles about 550, and flp long tubes 1200

Definitly go with long tubes they cost more but worth it.

Ive got Thorley headers and they are awesome. The midrange power gain is phenomenal. I had 100% TQMT added back in so I cant really give an accurate depiction of power increases there, but down low and midrange is an unbelievable difference. :hail:
BTW I think they are like $429 for the chrome ones.

Dynatech Supermaxx long tubes are nice, but probably the most expensive. You get the headers, gaskets, bolts, new Ypipe, high flow cats, and all is high quality stainless throughout. I just made some pretty nice numbers on the dyno with the only significant power modifications being the Radix (obviously), and the headers+exhaust system.

I had some clearance issues with mine, but overall its a high quality product.

I went with the Azsm Lt headers,and i am very pleased with them.Excelent fit and finish and great mid and top end gains,plus they are ceramic coated,unlike the dynomaxx.The factory cats are pretty high flow as is.So take the $350 yu save and put it towards a nelson tune.Ps if yu have a 4x4 the install of any long tube header esp the passenger side is a pita.
