so i wanna buy this exhaust from a guy, but he has a coupe with a 5 speed manual and i have a auto sedan. im prety sure seeing its just the header and dp it will fit, but we've been trying to figure it out with no luck. heres a link to what it looks like
OBX Header 06-08 Chevy Cobalt 2.4L Exhaust Manifold: eBay Motors (item 190349377171 end time Dec-08-10 22:30:52 PST)

 

Bump.
Anyone?

 

I believe auto's have issues with space underhood (since the auto traney is larger than the manual)

 

Not entirely correct.

The automatic 2.2s and 2.4s have the engine clocked forward towards the core support.
Which does cause fitment problems of some downpipes (flex pipes will rub on the front swaybar).

However with exception to the JBP (it wont fit 2.4 autos I know this for a fact) and possibly the ottp long tube and zzp longtubes (no information currently posted on fitment of these headers on autos) I believe all shorty headers will fit the autos. I have a zzp shorty and it fits fine. But I know my zzp 3 inch to 2.5 catted 5spd downpipe rubbed on my front swaybar bad enough that I had to take it off pretty quickly.

 

even tho i have the stock, smaller sway bar?

 

Most likely. I have a smaller swaybar than SS/SC's do and it rubbed on mine. Not all will. So you can always try and see. But if you do a trial fitment be sure to go for a drive. though mine would actually knock the swaybar on startup.

 

any way i could make it not rub or wear?

 

Not without rewelding. though its worth a shot to test fit it if you can

 

i dont think a test fit is possible. i'll b buying it off a guy for $60 and we're prolly gonna b meeting half way so i can get it. i'd test it right there in the parking lot but it will probably be cold and i dont wanna lug around my jack. its old and reeeally heavy.
anyone have any other info?

 

Go with a clearimage header and downpipe mine doesn't rub at all and i'm a auto just like you.
