QTP Header ?s I was considering buying a set of QTP headers and their ORY with no cats. Was wondering if anyone here has these and if they have had any problems with them. I feel like they are a good quality peice but just wanted to make sure before I purchase. Thanks In Advance.

QTPs are top notch! QTP LTs, although pricey, are one of the top rated LT Headers for our cars! I've seen'em in person. The quality is top-notch 
I went with Kooks because I got a better deal. Otherwise, they're both equally rated. I'm sure you will not be disappointed with QTPs!
Finally, I've read that QTPs have slightly better collectors
What seperated QTP and Kooks from others is quality, finish, fitment, and Stainless Steel [ as opposed to Mild Steel ]. All headers, from what I've read therefore no personal experience/observation, are same performance wise!
Hope that helped!

I installed some QTP HVM LT's on my car about 2 months ago. The install was very easy. Car's finally getting dynoed this week *crosses fingers* (it's been down for the past month for other repairs).
Can't say the Y-pipe was easy to install (I go the dual elect. cutout Y). Definately have an exhaust shop set up the Y if you're having trouble with it (it has quite a few components which conspire to do everything but go where
you want them to go- it's hard to align the Y without the car up on a lift).
Theoretically, it should be one of the free-est flowing Y pipes on the market given its design.

QTPs are awesome..
I love mine....
I had a set of other headers before...i sold them for the QTPs and never looked back!
The things that sold me over to the QTPs was the stainless steel, the available options[HVM(high velocity merges), Real Merge collector on the Y pipe, the QTEC cutout, and so on] i got the whole package

I'm curious if the HVM (High Velocity Merge Collectors) are worth anything. From looking at the pics of the collectors on QTP's site it looks like the collectors only go down to 2.5" at the merge and then out to 3" which I doubt would have any serious effect on power.
LG Motorsports has merge collectors on their LT Corvette Headers which go down to 2" at the merge and then to 3" and even they say it only adds 3-4hp.
I just don't see QTP's merge collector design being worth it, especially for the price of those headers.

Just got my qtp y-pipe in w/ cutouts. There are a lot of pieces, but hopefully that will allow me to fit it up better, than some of the single piece y-pipes. Also, the flowmaster collector is huge (4in outlet!) but i can't imagine any other ypipe flowing better than this one. SouthFL, any tips on installing the y-pipe, you said you had trouble?

^ Want my honest advice?
Take the kit to your nearest/ most competent exhaust shop. Fork over a bit of money for them to get the install right the 1st time and have them weld up the seams at the slip fit connections.
I fought with that Y-pipe for 2 evenings (with my car up on ramps) after work for a total of 8 wasted hours. I drove it, almost scraping the ground to Miami Mufflers where they took it apart again and installed it with the comfort of having the car on a lift.
