American Racing or Kooks?

**A_New_Level00** · 04-19-2010, 03:06 PM

Looking at buying LT's with emissions and a catted Y-pipe its come down to either american racing or kooks. Anyone who owns either have some feedback, and how is the quality of the cat and Y-pipes?

Either.

I went with Kooks, but either brand is great!

either are great. KOOKS at the moment are a bit backed up with order on F-Bodies.

Thanks,
Mark

I went with Kooks on our car. Very well made with an especially nice collector assembly. I had to nip the K-member just a touch to get the driver side header up in and then fiddled a bit with the catted Y to get the best clearance from the underbody.

My american racing headers just came in almost 2 weeks ago....very pretty

**Z28boy2000** · 04-19-2010, 07:42 PM

both are fantastic headers, next time around ill be going with ARH...pacesetters dont quite cut it anymore

Both are of great quality, can't really lose with either one.

Thanks for the info guys hopefully I'll be ordering some soon from either company.

there the same thing with slightly different collectors.....the people that own american racing headers used to work for kooks. one day everyone that worked there got into a big argument, half the people stayed at kooks half made a new company called american racing......just to give you an idea of how similar they are

I have Kooks and have no complaints.

Make sure to contact Mark who posted above for your purchasing needs. Great prices.

Both great headers, ARH has the better collector design on the header and y pipe..hp differences are minimal if any.

Did the driver side y pipe come flattened like that or did you do that for clearance?

**pewterz55** · 04-20-2010, 03:09 PM

why dont you buy both sets. then the ones you least like you can just give to me.

Driver side is flattened for clearance straight from Kooks. But, compared to the stocker, it has a positively huge cross section.

I have Kooks 1 7/8 and ORY. they tuck up nicely.
ARH flattens their y-pipe in that area too. I like ARH's y-pipe merge better then Kooks.

Yes it's much nicer! QTPs are nice also. Their the same quality but with a nice polished finish. They use a catted y with a flowmaster merge.

Mine aren't flattened, and i've never come across any ARH y pipe that's flattened. ?

**Cutlass** · 04-21-2010, 10:53 AM

I know I've seen pictures of it...let look around...
I was talking about the catted y in comparison to PaJeffs, maybe its just the catted y's with the flatten pipe. here's one I've seen.

heres another

Gotcha, in that case I think you may be right. I have an ORY..that may be the difference.
