alrite i have the obx stainless steel headers for the 2.2 and i keep blowing the gasket that is between the header and the downpipe!! the obx gasket was crap so i replaced it with a headman headers one which i also blew. i was just wondering if this could be caused by too much back pressure b/c i still have the stock cat on.

any help is appreciated

 

i dont know why it doest that buy i have the same damn problem man... but now i cant get a replacement gasget anywhere

 

Are you using the right torque specs?

 

i have no idea if im using the right torque specs. what did you torque yours too? i just tightened them as much as i could.

 

That's your first problem

 

Anyone know what most torque specs are on the gaskets, that way i know ahead of time. Doin an install tomorrow.

 

How do you blow the gasket on the exhaust manifold? Was it just shitty material and deteriorated? I've had my obx gasket since back in 03 and never had a problem.

 

I wonder if its the one between the header and downpipe, I just wanna know the recommended torque on them

 

its the gasket between the header and downpipe, not the manifold gasket. i just got a copper gasket so hopefully that one wont go. i still need to kno the correct torque specs though. anyone kno them?

 

Yeah, Anyone before I put mine on tomorrow.

 

i just emailed obx so hopefully they will respond. ill let you guys know. seems like people need this information.

 

Thankx man.

 

The correct torque specs are:
- Exhaust manifold self-locking nut (header to manifold): 23 Ft.Lbs / 31 Nm
- Shroud bolts (heatshield): 16 ft.lbs / 22 N.m
- Exhaust pipe flange nuts (pipe to cat, cat to pipes, etc.): 40 ft.lbs / 54 N.m
- Flexplate bolts: 54 ft.lbs / 73 N.m

i don't think that's what he needs... he said it's "between the headers and downpipe" so it's probably the triangular gasket...

like this:

no... your both wrong. it is triangular, with the two exhaust holes and the three bolt holes. obx still hasnt returned my email > but i replaced my old gasket with a new pacesetter copper gasket and so far no leaks. woot! hopefully it stays this way. i just tightened the bolts till they were real snug.

 

alrite i just got the the email from "dave" at obx he recommends 75lbs for those three bolts.
