I got the Kooks before QTP made the HVMC's were standard, simply because of the Kooks y-pipe fitment. They slid in with zero issues, only had to remove the dip stick to get to a manifolds bolt. I am very happy with them and I lost very little ground clearance.

If I had to do it again I would seriously consider the QTP with HVMC.

I just ordered qtp's from ws6store (awesome guys btw). I hear they're coming at the end of june, early july which is no big deal for me. I just hope their quality is up to par for holding the shipment this long. I'll let you know how they install

I just didn't feel like waiting any longer for my QTP headers. My car kept getting pushed off as so as it is so the moment i got a chance to get it all back together i did. Thats why i just ordered the headers i could get the fastest when i found out it was going to take so long with Quick Time.

So whats the difference in power and TQ between the qtp with hvmc and kooks with out hvmc?I bet its not much maybe 5hp and probly no one knows.

i have my QTPs up for sale in the forsale forum, they are practically brand new, anyone want them without having a wait time through a store/sponsor? : https://ls1tech.com/forums/lsx-parts-sale/526528-qtp-long-tubes-pic.html

It would be an easy decision for me! QTP's are equal to the Kooks quality wise, are cheaper AND come with a HVMC!

This article is not a comparison like you ask for, but it does have some good HVMC tech info.

Neither... They both suck!

I'm thinking this is what you want to hear, being that all the million other posts talk about how great both of these fabricators are. If you have read anything on here, then you would know that these are the top choices. I am starting to think that the majority of users on this site are either full of **** or they are simply children. I think I'll puke if I see another QTP or Kooks? thread.

Are you basing this on dyno results and/or track time slips? Or fitment issues?

Both QTP and KOOKS have had some very satisfied clients on this site who have seen great improvements over other headers on the dyno (myself included). For me, fitment and quality was first rate, but from what I understand, new batches of QTP's are not manuf. by the same people (as of 6 months ago) that made my set.

You must have missed my point. I have Kooks and think they're excellent. Everybody knows that they're great headers. I just don't understand why we see a new thread everyday from people, asking if they should get QTP or Kooks. People should really read the **** that has already been posted and tossed around at least 1000 times.

Ah, point missed.

I'm somewhat of a noob over at the WRX forums and I appreciate those who offer feedback to a question, no matter how repetitive it is. Search doesn't work sometimes and long tubes aren't a cheap item, so sometimes people need a little reassurance before committing to a purchase.

I just read the article posted by southfl.02.ss and it says that hvmc's are also known as venturi collecters so if this is so and all kooks headers have venturi collecters then please correct me if I am wrong but this must mean that all kooks headers have hvmc.If so I have to LMFAO cause if you are smart and spend the $250 getting your headers ceramic coated(which you should anyway) then the free stainless polish from qtp dosent count does it?And the ill fitting Y pipe from QtP is a negative so on that note the kooks are better and reign supreme.LOL

People that have QTP headers will say to chose QTP. People that have Kooks will say to buy Kooks. Just pick one, both are going to be about equal.

The hvmc are also known as venturi collectors, but the regular kooks don't have merge (or venturi) collectors. The kooks do have a turbulance spike, just like QTP, but no merge collectors unless you want to pay $1300 versus the $725 for QTP.

Go with the QTP's. I've used them and loved them. Went in easy too.

Many people here would argue that coating a stainless steel header is a waste of money.

Well I just got my kooks headers with 02 fittings and venturi collecters at no extra cost. I thought someone said I had to pay an extra $500 for the venturi collecters from kooks?

Cobraeater

You have a turbulance spike, not a venturi collector.

Here's QTP with a regular collector which should look exactly like your kooks headers.



And here's QTP with a merge (venturi) collector.






Kooks says their regular headers have venturi collectors but that's wrong. A turbulance spike isn't a collector.

Here's a pic of a turbulance spike.

Do you see the difference now?

Damn those QTP's look fine but looks like your right I will post pictures of my Kooks soon so you can see but for me the venturi thing does not really matter I guess its nice to have all the extras for less but I wanted the 1 7/8s headers from kooks as I am going for a H/C package, 383 stroker and 90/90. QTP dont make 1 7/8s yet plus I heard a lot of bitching about the y pipe so all that made up my mind for me but those QTPs really look nice.
Also I guess 10 hp is a great bonus on a bolt on only car but my car is almost full bolt on now and after my Konis,sway bars and springs get hear I will order a 3500-4000 stall then the stuff mentioned above and my car should be 450hp to 500hp at the wheels NA and I dont think I will care about the 10hp from the venturi as this is my every day car and I have a wet system for track days and if I need to get really serious with someone on the street .
