Kooks or QTP ? How to choose?

thats the thread my friend posted. I guess it was only a problem with the catted y-pipe. It seems if you are doing a ORY then the QTP y-pipe is fine

We are having a sale till the 31st, so get em while they are on sale.
Kooks and our headers are based off the old grotyohan design header so we are similar.
my QTP headers and catted Y are fine...the drivers side catt is alil low but big deal...your gonna have less clearence with any 3'' Y you put under there, expecially if your compairing it to the stock Y...and add a catt to the Y and the clearence is even a tad less, but that should be expected...all in all there both great systems, so get what makes you giggle...

I had a good friend that had a lot of problems with it and he listed a post and about a dozen other people had the same problems fitting it. Do a search on the QTP ypipe before you buy it to see what others had to say. I never had any problems with my kooks ypipe..

I would say go with the cheaper ones because both are great. But I just installed Kooks LT's today and it feels like I gained about 25 HP from them and my exhaust, it sounds great too 
. No clearance issues either fit pretty dang good. I'm gonna have to go on the Dyno next weekend

i dont like cats personally they make me
I do like the qtp merge collector and their ORY setup for cutouts....
qtp is my vote.... unless kooks is more than 75$ cheaper at the time.

The only real difference in the standard systems is the y pipe. QTP has a nicer merge collector and their cat is set further back for clearance (I assume) reasons, Kooks cats are right after the header which would make them work a little better. Service from both is good although I am slightly biased toward QTP since they are selling their headers direct. Matt at TTP has good prices on the Kooks and several have commented here about his good service.
