Which would be a better Header as far as performance gains and Quality . Thanks

 

I would universally choose any long tube header over Macs. Not to say that Macs aren't good, but theyre not long tubes!

 

I would agree with the Pacesetters as they arte a LT design and should give you a few ponies more mostly stock, and maybe 10-12 more on a H/C setup. Personally, I'm waiting for some more dyno details on these before going with them, but they seem very good for the money.
