    No.
    You aren't going to be in 15's with just headers, exhaust, and intake. Unless you have a performance TQ and rebuilt tranny or you are a good driver and you have a 5spd galant.

    I'll be making a parts list for the members here that wish to stay N/A and would like to be in the 13's/mid 12's. I'll also have a part list for the 5spd members here that would like to beef up their tranny and don't know what/where to get the parts to do so. Expect it up in like two weeks.

    I dunno, Headers *could* drop you one second in accordance with the proper other mods. Ya gotta think of RPW's "mod path" on their site. I'd have to go look, but I think headers are fairly low on the list. But 1/2 second is probably more reasonable. (For those who don't believe me, I once saw a dyno test on a supercharged V8 muscle car of some sort where they picked up like 40 hp just going from the stock muffler to a straight through muffler. It just depends on prior mods)

    Uhm, I do. Of course there are gains, there are always gains when using aftermarket headers. Why would any company make equal or more restrictive headers? Doubt they will sell very well.. :?

    It's a 4-2-1 design, what more would you like to know? There is no dyno sheet yet on a stock 7g for these headers so... I estimate about 7-10 HP if matched with a high-flow cat and muffler.

    Headers

    We only had 7 to ship to the USA as the other 6 units had already been sold to several cars in Australia etc.

    We will be manafacturing more so have no fears. We on average send a pallet of extractors over every 6 weeks to Vision so there is not normally a problem getting these units there.

    Headers

    All RPW units are 4-1 we have never made a 4-2-1 system ever. Probably a typo error.

    Headers

    Great to hear - whoever it is though, one set of headers we had sent direct from the manfacturer to Vision Imports which means we did not get a chance to face, straighten and de dag the header section like we normally do.

    These were sold cheaper to Vision Imports to compensate the customer who would need to do this work to them. Just a warning to that person who does buy them that they do need to go to an exhaust place / machinist and get the flange face checked for being straight and then machining the face to ensure it sits square on the cylidne rhead.

    Our other headers have already had this done but we had one set at the manafacture which we added to the order to try and send some more across.

    This is not going to cause any problems so please don't panic. This is just to ensure that the person who gets them ensures they do get them checked unless Vision have already organised that.

    headers

    Yes it was only 1 set of headers and flex pipe out of the whole 8 sets sent across. And it is the set that left on the pallet last week so Vision don't have it yet on there floor.

    Well that should be done on any part. Cylinder heads, engine blocks, intake manifolds, exhaust manifolds, stock or aftermarket. If you don't check it then well...
