[QUOTE=ChocoTaco369;8645357]QTP's are longer,
Choco, Do yourself a favor and measure both. You'll find this isn't the case.
MUSCLE96SS, One thing that hasn't been mentioned here is that at ARH we don't take for granted what your upgrades are and just sell you a generic header system. We are not a one size fits all header company. When anyone considering our headers takes the time to call us, we'll ask the important questions and make whatever adjustment our system needs to compliment your combo.
More times than not our basic systems are more than adequate. But that is not always the case. It's been mentioned here that our Y-pipe is excellent but may be a bit short on flow when compared to QTP's. This information is incorrect. We can custom size our Y-pipes with a 3", 3-1/2" or 4" outlet. How much flow do you need?
Our merge collectors are fully welded. This totally eliminates any possibility for leaks which can alter O2 sensor readings. Our merge collectors can also be custom sized to better fit high HP or large cube applications.

It's T-304 stainless, the same stainless everyone else uses with the exception of SLP and XS.
[QUOTE=ChocoTaco369;8645357]QTP's are longer, look better and are a lot cheaper.
ARH's have a better y-pipe.
If you're going TD's, I wouldn't even consider ARH. If you want a y-pipe setup and don't want to put the time into getting a custom y-pipe made (which can come out to be considerably cheaper in the end), then you may want to consider ARH because their y-pipe is nicer.QUOTE]
Why would you not consider putting TD on with ARH?

The placement of the 02 bungs is perfect as well. The driver side? 02 bung being on the outside solved a lot of issues! Great feature!

I haven't had any experience with ARH so I can only go by what I see and read. I think QTPs are a little longer because in all the images I have seen of ARHs on a car, the cats' are farther forward than where the cats' on my car are positioned. I will grant that my cats' are a little longer, but the collectors on the QTPs seem to stretch a little farther back. I only have pictures to go off of for ARHs though, so please take my observations with a grain of salt.
I've installed three sets of QTPs - two on my car (the first set was standard-collector,) and one on my brothers car. There were clearance issues on the passengers side of the K-member that a little grinding took care of - no nig deal. The Y-pipes were a different matter, mostly because of interference with our SFCs. I dimpled my brother's Y-pipe, and customized mine by replacing QTPs cats' with another set of Magnaflows, and replaced the drivers side leg off the cat' into the Y-pipe merge collector. My clearnace is fine now and I have no complaints. If QTP didn't try to use full-size cats' they wouldn't have to put the drivers side where they do (in order to fit under the body.) Additionally, I don't know how much I trust the welding in the merge collectors on the headers themselves. I found leaks on my brothers LT and QTP exchanged them (I didn't verify these were any better.) I found leaks on my LTs and just used some exhaust manifold repair expoxy (which SEEMS to be holding up for the time.) I like how it seems the QTPs merge collector comes together a bit better than how the ARHs do, but that's probably not too important.
My $0.02: I haven't seen too many complaints about ARH-period. Nicer Y-pipe, all the way around. Maybe QTPs LTs flow a little better but the quality of the collectors worry me. FWIW: I don't know if/how ARH could improve on the welding in their collectors because of the primary pipes snaking into the entrance of them, so this point may be moot. All around, I'd vote for ARH-better Y-pipe, primary choices, active on this forum, and from my understanding, great customer service.

And you'd be surprised the kind of power difference between brands of headers. Going from one brand of headers to another can yield serious losses/gains in power depending on which brands you swap from. "All longtubes dyno the same" is the biggest lie ever told on LS1tech, and it's told and awful lot.

My LSx C3 (82'), has an F-Body style setup. In other words the T56 is attached to the engine and not a transaxle. However, the motor is further behind the front axle than an F-Body. If the headers angle back and hug the block well, I think I'll be alright. If the headers come away from the block all that much, I could get into trouble pretty quick.

Theres something you dont see everyday Coco taco getting corrected.. LMAO!
Once again Taco is the purveyor of bad information.
I just ordered ARH. QTP are nice, but ARH are nicer. Power gains from QTP over ARH?? I'd like to see the proof.

Because the only advantage of going ARH is the y-pipe. From all research that has been done, it looks like QTP's outperform, not to mention they're polished and they're $200 cheaper. If you get the ARH kit, I understand because their y-pipe is a lot nicer, but that's the only real advantage there is. If you're not going to buy the y-pipe, there's no point unless you want to spend more money for no real reason. At least that's my opinion, so take it with a grain of salt.

ARH:
Look real hard. Which is obviously longer?
There's a reason why QTP's tend to hang a little lower and are a little trickier to install, and also why they dyno so high compared to everyone else. They're a longer design. QTP still advertises them as the "longest longtube", plus they're equal length, so I'll stick with the obvious on this one.

The headers aren't sitting on the steering, so even if I took the pic, there's some clearance so it's misleading. Again, there's only a slight intermittent tap when the car idles higher and rougher upon cold start. It never taps while driving and once warmed up and the idle drops and smooths out, there's no issues. Besides, the F-body design will be different than yours, so just because I get a tap every now and then doesn't mean you will.
I can show you them in the engine bay:
Not sure if this will help or not, but it's worth a shot.
i know what rust looks like, they are probably a year old. they are rusting down where the collector is. when i can i'll get pics

And I don't mean to insult you here, but are you sure they're QTP's and not SLP's? Did you buy the car with them on there and someone just told you they were QTP's or did you buy them yourself? I'm not trying to insult you here, it's just an honest question.
Thanks, this does help. Snapped some pics tonight to give an idea of the clearances I'm working with. The driver side doesn't look like it'll be too much of a problem, but passenger side could be a close call with the steering rack bracket. Sorry guys for the large number of pics, but before I throw down, I need to have as much confidence as possible that it'll work out.
PASSENGER SIDE (Biggest Potential Problem I Think)
You can see the EGR boss (I have Stock 01' Headers comes very close, but clears the bracket.)

^^^^^^i dont think you're gonna have enough clearance on the passenger side. the turn down off the flange is 3 inches long, compared to the stock exhaust manifold 2 1/8 width. idk doesnt look good to me but hell i could be wrong. wouldnt be the 1st time.
