Hey Mystery Z28, if you find out anything good or bad about those QTP's can you email (loudmouthls1@aol.com) me and let me know, cause right now i'm very interested in pickin up a set of those! I was originally going to get a set of jet-hots, but these look really good, and I think i might go with the QTP's if there are no issues with them and they put down good power. Thanks man.

 

sleeperZragtop basically tuned means they are made with the stock cam in mind. The flow characteristics are fine when you're stock but when you change out the cam they become more restrictive. That's why if you ask SLP owners where the power is it's down low & mid range (I had SLP LT's at one point) :thumbsdown: Where as FLP's are all about top end which is what you want on a heads/cam car. How much of a power difference depends on what type of set up you get. The general rule is that if you're staying stock then it doesn't matter your power curve will just be different but on a modified car you want top end. FLP's are not tuned. It's also not b.s., it's a fact. SLP even pushes the fact their headers are tuned but what a lot of people don't realize is that if you plan on at least adding a cam that's not what you want for max hp. FLP's are top notch headers & are a very good choice.

 

So far, I have heard nothing but positive points about the QTP LT Headers, which I can't say for the rest. I think every set is going to have its negative stories but what you have to look for is the set that has the least amount of angry buyers. Plus those QTP LTs look astonishing!!!

 

See, I want to go with the hookers straight from jet-hot, b/c two of my friends have them, and their amazing and have no problems, so that probably is what i'll go with, but I want that qtp y-pipe with the electronic cutouts!!!! That **** is ill!!!!!!!! Do you think that would fit the hooker LT's? If anyone has any ideas about this, please post and let me know, cause I would love that combo of the hookers and the qtp y-pipe!!!!

 

please stop talking out your ***... flow-matched headers are JUST FINE for street-strip cam. most of the headerrs on the market are 1 5/8', and a flow-matched or "tuned" 1 5/8" header will allways outperform a non-tuned header.... (to understand what "tuned" really means, read my prior post.)

 

LMAO you're an idiot. All the aftermarket headers are 1 3/4" except the new Grotts also offer 1 7/8". A tuned header will NOT out perform an untuned header unless the headers are tuned for the cam you're running. In the case of SLP's they are tuned for the stock cam so if you upgrade they become inferior.

 

sorry typo, I meant "1 and 3/4" just as the SLP are...and as many others are. my bad there, but you are still a fool. a 'corrected' '1 and 1 3/4' header that is tuned will allways outperform a 1 3/4 untuned header.. you are a fu*king moron, headers are not tuned to a cam you fool. 'tuned' means they are matched in equal length so they are volumised.. read some, and sorry, but you are talking out your ***, and you are owned. sit.

 

the only sense you are right is if you upgraded your cam to the point where you needed a larger diameter header to meet your needs... but then both headers would be inferior at that point. you have a lot to learn.

 

I was thinking, my GMMG Chambered Catback Exhaust Systems piping is 2.5 in diameter but if I'm not mistaken, the QTP LT Headers y-pipe is 3.0 in diameter...so how will I get them to fit?

Is this a stupid question? Or am I in trouble.

 

Mysteryz28, the GMMG is 3" at the i-pipe. just the chambers and back are 2.5"... so you won't have a problem at all

 

Be careful with the QTP headers. Although nice if he didn't change the design too much they will be a pain to install. You will need to be able to get your car up HIGH. You will basically need to have the driver side header flanges vertical to get them in there. When we installed Grotts on my car we had the car jacked up so high the rear bumper was nearly touching the ground. The Oil drain bolt was also in the way so we had to drain that out as well.

Every header system has their good points and bad points. There is no "perfect" header. The only headers system that has consistently had happy buyers has been the FLP's.

BTW don't get the 1 7/8" unless your planning on some big cubes. Otherwise they will be a waste and you'll loose some HP.

 

QTP Long Tube Header 1 3/4" Coated Emissions Style
QTP Long Tube Header 1 3/4" Coated Race Style
QTP Long Tube Header 1 7/8" Coated Race Style

So which is the best set for my car? Pretend that money isn't an issue but I don't want to lose hp. Are race style street legal?

Thanks.

 

Well, unless you have big cubes, you don't want the 1 7/8 cause it won't help you and the 1 3/4" emissions and race are the same basically, the only difference is the emissions has the egr hookups, and the race is if you don't have the egr, somebody please correct me if i'm wrong, but that is my understanding.

 

From what I've learned, read, and seen. I'm going to go with the Jet Hot longtubes. Can't beat the price and they've refined hooker's design by putting the o2 bung on the inside of the collector which makes install much easier. They've made a few other improvements that aid in fit and finish. They'll be getting my money shortly.

 

Well since emmisions are an issue unless you want to wait a while longer QTP's are not for you. They do not have a Ypipe with cats as of yet. Any LT are technically not "street legal" because you moved the position of the stock cats. Buuuuut most inspection stations don't care as long as you got em. Since your a 02 EGR bungs are not a concern, but I do believe you still have AIR tubes. Your going to want emmision style but make sure you tell them what year it is.
