Well I have been a firm supporter of the QTP side, but last night I sent payment for a set of xs headers and y pipe. I will take pics of whatever and post whatever yall would like to see. Feel free to pm me with any questions about them and I will answer anything that I can. I have owned Qtp's, and pacesetters so I will beable to give a decent opinion lol. But we shall see how it goes.

Do you have a set of XS headers? I already know the answer to that because if you did, you wouldn't have posted. Please don't post information about a product unless you have personal experience with it.

Same situation, is 5hp worth $300-$500? If it is to you, then there's no need to argue because we just disagree.

I don't understand why the fact that these headers and others like them, being made overseas, needs to be such a secret. Obviously folks are willing to buy them due to price. Maybe they're concerned the more patriotic consumer won't want to buy their performance parts knowing they come from the land of the Rick-shaw.
Do you own a set of XS headers?
If the answer to this question is no, then don't waste our time.

I have one question for you and that's all:
Do you own a set of XS headers?

And if everyone went by your analogy, why waste money on a good cat back like- borla,corsa, etc. when a cheapo flowmaster will do, heck why use any good brand name parts on any of our cars, lets just save money and throw in the cheapest stuff we can find.

Sound is almost MORE important than power in a catback. No one worries about how headers "sound". Quality and gains are what everyone is looking for.
Generalizing will not ALWAYS help your argument, so think before you try it.

My analogy is speaking of items of similiar quality, and addressing power. Your comparison is totally different.

Explain to me how i'm "settling for less" when i'm getting better quality parts for a better price.
This i'd like to hear.

You settled for a low end budget header. QTP's are,ported at the header flange. You wont see left over weld here.
Stainless steel is better, compared to mild steel, stainless steel has superior high temperature characteristics. It is an excellent material for headers and any application where high heat is encountered.
Stainless steel has a much lower coefficient of thermal conductivity, thereby keeping more heat inside and transmitting it to the header outlet. Radiated heat is perhaps the most important reason to wrap or ceramic coat the headers to protect the car and the driver from excessive, fatiguing high temperatures.
Typical 1010 carbon (mild) steel conducts 219% more heat per foot than do the types of stainless steel used QTP's header fabrication. By contrast, quite a bit more heat stays inside the stainless header tubes and does not get passed into the surrounding air. By not allowing the contraction of the cooling gases as they flow down the tubes, more exhaust velocity is retained which promotes better scavenging at the collector.
This retention of velocity increases the overall header efficiency. 304 stainless steel has excellent high temperature fatigue resistance in enclosed application and does a darn good job of living in this hostile environment better than any other material.
These many characteristics, such as superior heat retention properties, high temperature fatigue resistance, and to a lesser extent, the cosmetic value of a non-rusting finish, combine to make stainless steel an ideal choice for headers.

no hes comparing pacesetters i believe?..........either way im just beating a dead horse, sorry blackbird it comes down to personal preference
People spend $3k on wheels and then $1k on chrome/carbon engine dress-up, so whats the big deal if you got the dough.

You need to actually read all five pages before poppin your head in here and talking crap about something you obviously don't really know about.

I also agree that personal preference prevails. I'd never dispute that. You buy what you like. My whole argument was against those who are trying to claim that QTPs are "just all around better" because they definetly are not. When I got my XS headers, I expected a lower level of quality as compared to QTP and Kooks. What I got is clearly superior to QTP and possibly even Kooks. I was surprised and now i'm trying to share that impression with others.

It looks to me like I came in here already informed and passed that information on to you and some other uninformed folks. I could be wrong but it definetly looks like that to me.
