The top 3 are qtp, kooks, and arh...does anyone have any dynos that compare these to each other...I have tried looking and only found a pacesetter vs tsp header...this is not an opinion thread unless you have some related experience...

I will post up in the dyno section too...thanks guys...

I am looking for that 500rwhp a4...

i cannot speak for the others but my kooks fit better than my slp headers did and way more ground clearance

I didn't think that QTP had any 1 7/8" headers. Typical size is 1 3/4".

kooks 1-7/8's here...
plus fast intake and full exhaust... stock everything else

only dyno results comparing 1 3/4 o 1 7/8 or two sets of 1 7/8s tested...I know the second one is a stretch...

giving dyno numbers of your setup without a comparison doesn't prove which header is better...look at my setup 485rwhp a4 with 1 3/4 qtps...doesn't mean that I couldn't make 490rwhp with another set...would just like to see comparisions thanks

Might be a stretch to find comparisons of these, I am curious as well though.

I don't think you could go wrong with either header.

I think your trying to split hairs here.

Unless your trying to race pro stock, brand of headers isnt going to make that much difference.

If your really getting picky (as it sounds you are) than find the set that bends the least amount right off the flange. Sharp bends right outta the combustion chamber will rob power, but the way the motor is in these cars its hard to do without sharp bends at the flange.
