Will these work with the 2.4? Is it too large of a diameter, and/or won't fit?
Has anyone else done it on a 2.4?



Because I just saw a video, and it sounds ******* amazing.

 

yea i know sounds like a wrx kinda...very sexy but hard to get

 

search bro....

Yes, but will it fit?

That's for the 2.0 though.

 

wont matter... exhaust outlets are the same bolt pattern... youll be fine...

 

couldnt see why not they got same stock headers as us

 

Yeah, I know, but the thing is that the LE5 on the Cobalt isn't listed as being supported on the website. Do you know of anyone who has installed this on a 2.4?

I really just want this for the sound (because it sounds amazing on the SS/SC), but will I still get that sound on an NA application?

 

youll be okay... but dont look to be getting 31hp gain... just to tell you.. the header has some restriction to it...

 

X2 I want to know how one would sound on a 2.4

 

guys it will sound the same just without the whine...

 

Yeah, but with this amazing sound, I really don't care about performance, as long as I'm not losing hp.

Thanks for the info, I sent a PM to JBP to see what they say. Are they good with PM's?

hmmm i pm'd them too, i want this thing bad

 

He got back to me. He said it will fit, but you just have to move some stuff around like the A/C line.

SOOOO ORDERING IT

when I get the money, that is

 

actually, this is the best flowing header on the market...

it would fit a 2.4 unless you have extra **** in the back behind the engine that the 2.0 doesn't have. you'd also have to lose the engine plastic.

 

Yeah, it looks like there's quite a bit of room behind the engine. The only thing I'm wondering is what about it takes three hours to install? As opposed to a regular header which I hear usually takes 45 mins.

 

I bought a blemished header that required mods to the coolant crossover tube. Long story short I had it on and off a dozen times or so to take measurements and build a fixture for a new tube(nope it's still not finished I got sidelined with another project). You probably don't have to, but I dropped the front engine mounts to tip the engine forward and pulled the rocker/valve cover to make more room. One of the things that takes awhile is removing the studs in the collector and the head. With air tools it takes about 1 1/2-2 hours to pull everything, swap it all over, and put it back together. Hope that helps.

 

yeah, you've seen pictures of this thing right? it's a beast, and it's probably the tightest fit ever. i would recommend solid mounts along with this, but thats just IMO.

 

are there solid mounts available for the 2.4 well the auto version anyways.

 

What would solid mounts do?

Yeah, I think TTR just came out with them. But I thought they were just for traction.

 

yes, ttr just came out with mounts for the auto guys.

mounts would keep the motor from moving too much, because this header is such a tight fit, if your stock mounts were too soft, the motor would move to much causing the header to bump into the firewall, and that would be bad.

 

This header has to be installed from below...

It does sound pretty crazy though....

 

Gotcha. So where on the engine is the mount positioned?

 

it replaces the factory mounts.....

there's the main mount on the passenger's side of the engine bay, and two transmission mounts on the bottom.

 

someone needs to put this on, do a how to, exhaust videos, and how the hell it fits. then you would be king
