I am not putting out any PSI. I have the 2.4 SS.

 

I WANT THAT HEADER SOOOOO BAD!!!!! IF IT DIDN'T COST MONEY I COULD AFFORD IT!!! WHY CAN'T THEY BE FREE!!??!!??!!

 

ill probly wait to see what everyone is putting down before i make my decision.

 

I want to get a good header, and the quicktime electric cut-out put in before the cat. So I can have super high flowing exhaust while racing, and street and emissions legal exhaust for the street.

 

Is this header good for the 2.4? and does it line up with my catback, I have the GMMP catback, because too big might not be good for us 2.4 guys, im hoping its 2'5 in diameter

 

the header will fit the 2.4 perfectly. The primaries are 1 5/8's (the ideal diameter) that go to a 3 inch formed collector that will fit up to the stock exhaust setup position. So as long as you dont have a custom exhaust yer good.

 

you might want to check your local emissions laws first... i think its actually federal law that you can't modify ANYTHING in the exhaust thats pre-cat unless the vehicle is out of the OEM emissions part warranty.. of course, my toolbag former auto tech instructor from 2 years ago is the one who told me that, so the accuracy would need to be verified. Generally speaking though, most states with emissions will still fail you for a pre-cat cutout even if it is the wingnut type thats bolted shut. Not saying its illegal in AZ, but you'd definitely want to get that in writing from somebody in the legal profession or something.

 

for $600, ill pass. can get a long tube header with a MUCH more direct exhaust route for $100 more, or a complete header and downpipe package for less or approx the same. for basically a shorty header, $600 is way too much. IMO those bends do more harm then good. everybody always preaches less exhaust restrictions on here, so that is an awfully not of bends in the very beginning of the exhaust system. there is no turbo at the end of that flange, so the exhaust gases do not need to be routed for a correct and even flow, so i just say get the damn exhaust gases outta there ASAP!!!! i feel the same gains can be had with any of the good shorty designs out there (cough cough* dyno comparison anybody )some of the primaries do a complete 180!

then again.. this is just my opinion

but it does look like a marvelous piece of craftsmanship

 

Im feelin the same way

 

the advantage with an equal length header is that when the cylinder exhausts it's gasses, a sucking action is caused as the after it passes the collector, essentially sucking out the exhaust gasses quicker from the next exhausting cylinder. and so on.

this allows the engine to breath much better.

it is much easier to produce an equal length long tube header then a shorty because of the space ristrictions.

now the major differance is where do you want to gain more power? Top end or Low end.
that's where you make your decision on a long tube or shorty header.

 

Player I like my power more low to mid, what header would be most benificial to me ,Thanks!

 

that pretty much is what i was going to say. but i mean, is this really a shorty header anymore? the primaries are super long... its more like a compact long tube 4-1.

 

^^^ i should also ask whats the primary lengths?

 

shorties are better for cars with a tight powerband, so you'd probably be better off with a shorty, but over the entire power band, you'll make more power with with an equal length 4-2-1 longtube. $$$$

so a good shorty will make more Torque up until about 5-5.5K RPM, after that a good long tube will make more power. also vary high horsepower cars will benifit more from llong tubes as well.

that means you, you should really think of a good equal length long tube header for the power you'll be outputting.

basically for headers it's like this:
4-1 shorty < =length 4-1 shorty ~ 4-1 long tube < 4-2-1 long tube < =length 4-2-1 longtube

also anther factor that fometimes make the lung tube better, is that they sometimes delet the Cat., or come with a larger better cat. the the stock.

 

Thanks Player! I just got a pm with the same response,Im goin to stick with the ClearImage header just got to find out if it is 1 5/8

 

a compact 4-1 long tube only makes power, cause it delets the cat. and it helps abit with the top end. that and they are rarely equal length. personally they cheap design and not worth the money, a good equal length short will make more power especially if you delete that cat as well with a down pipe.

as far as the lengths I don't know what they are.

 

no prob, good luck

 

When your at the shop next week using up all of Mev's time (that he could be working on my engine) just tell him to use the best thing for my header needs. Oh wait I need a header for a turbo system and I think that changes things?????

 

lol
I forgot about that, never mind stick withthe shorty
has the "designer" told you anything about the twincharge setup yet?

 

I'm not worried about it, if I can't pass here in chandler because of it, then I'll just register my car at my aunt and uncles house in flagstaff, theres no emissions requirements in flagstaff.

 

I know regular price is 670+tax, so GB price should be a good deal, more info if about pricing, order date deadline, and wait period for the Header,
ON JBP website, it says for one header 2 weeks, which is pretty good, if this GB goes through they will be pretty busy......

i hope this is ok,
they have a pic on their website of the header, though i would post to show

 

I'd like to hear more opinons on shorty with/without cat vs long tube before I add myself to this group buy.

 

you could buy the ZZP downpipe to mait with this, for added performance. or the XTC downpipe

 

what more is there to hear?...you decide what header is right for you.

Long tube equal length = more high end power and torque
Short tube equal length = mid-high end torque and HP
