Injen Exhaust - UPDATE
My suggestion is to order the exhaust system through your dealers parts and service department (mine will order it, dont know about yours) have them install it (pay through the nose) and have them personally warranty any problems that might occur (good luck with that)... Anyways, a little off topic... Does anyone have any idea of a ball park figure for a system like this, like someone that maybe had this on a different car. A header isnt cheap, neither are mufllers, are we expecting 800-1000 dollars for this?
if that includes the headers, then that's not too bad of a price... but given the description is "header back" my assumption is it does not. So, 800 to 1000 dollars for a mass produced exhaust 'kit' seems a bit steep, IMO. But that's just my opinion.
"Header Back" doesnt make sense to me. Are they supplying a header with the kit, do they assume we have a header, or are they just calling the exhaust manifold a header? Am i the only one having trouble with this?
every car has at least a header stock lol, they are just restrictive and thats why they are usually replaced with higher flowing versions, inline engines have one header and v engines have two headers on each exhaust side
header back systems I thought were everything behind the header. meaning replacing the CAT + exhaust system
not a "header + cat + exhaust system" your looking at a 1500 + cost if thats the case,
but hey, what do i know.

When I see a "header back" exhaust system in a catalog, I know the manufacturer expects me to have a header already. When I see someone posting on the forums, I have to asking because of people like you not distinguishing the difference between a header and an exhaust manifold.
It's for the sake of clarity that I call a header a header, and an exhaust manifold an exhaust manifold. They perform the same function, but they have different construction methods and have different goals in mind when they were designed.
So, in the future it may be wise to take the terminology used in the question into consideration before you start 'lol'ing at people like they're 'newbs'. Some of us like clarity in our communications.

It's not a header unless it's an OEM "high performance" part that replaces the mass produced part that is normally referred to as the exhaust manifold. To clarify my meaning, a typical exhaust manifold is constructed of cast iron or casted steel with low cost, high production volume 1st in mind. A header is usually constructed from mandrel bent steel tubing a designed with performance first in mind.

Well thank god we live in a world where somethings can be reffered to as something else and still be correct. So, I can say this and still be correct: 'Replacing the stock HEADER with a high flowing aftermarket HEADER, and replacing the entire stock exhaust system from the HEADER-back with a less restrictive aftermarket HEADER-back exhaust will more or less increase performance.' Then, I 100% DOUBT that a manufacturer like INJEN would already expect you to have an aftermarket header installed to be able to use THEIR aftermarket exhaust. My reasoning for this is simple: 1.) you don't require a customer to have something that you dont supply, just to be able to use your product, 2.) It's bad for business, 3.) It's just stupid!

2) It's not bad for business. If it's a product people want they will buy it and do their own fabrication work to make it connect to what they have, or design their own exhaust system to better exploit the new header. How do you think 'custom exhaust shops' stay in business? If everything were 'plug and play' as you seem to think it should be, then there would be no need for them.
3) In your opinion, it may be.
Fact of the matter is, in the automotive world headers (high performance after market) do not always come with flanges for connecting to the stock exhaust. Nor do they always fit into the same space used by the OEM manifold. Ever seen a "tri-Y" header with "slip fit" connections at the collector? What about a 3-into-1 header? 4-into-1? A "shorty"? I can guaranty the OEM equivalent did not use 'slip fit' connections to connect the manifold to the exhaust. Additionally, many high performance headers use a larger ID tube for their collector than what the OEM manifold uses. Thus, the header cannot be used with the stock exhaust system without end user modification/fabrication.
If the company making the header can make a better header by not conforming to the dimensions of the stock manifold, then I would expect them to do what they need to do in order to achieve the best possible performance out of the header. Limiting themselves to the space the OEM used only helps in making a 'plug and play' component, and does not necessarily make it any better than whats already there. Sure, that'll help them sell lots... but the part just became a 'bragging rights' part if it doesn't have better flow characteristics than the OEM part.
(back to #1 again) There are companies out there that specialize in making headers but do not make exhaust systems to go with them.... "Hooker Headers".... "Pace Setter"... etc. And most of these headers have collectors that are larger diameter than the stock exhaust. Connecting up a stock exhaust to one of these headers is kind of moot. Sure, you'll see a little gain, but you still have the rest of the stock exhaust choking your engine's ability to breath. Hmmm... these company's are successful... Looks like making 1 part and requiring the customer to go on their own to make the most of it is working pretty well for them.
