I have just ordered an OBX header w/ cat from helix...
http://www.helix13.com/mini/products/exhaust (at bottom of page)
...and while researching info about header installs, I came across something about the stock header bolts not being suitable for re-use. I.E. - they are only meant to be installed once, after that, the little teeth that grip the header are worn out and thus, loosen very easily.

Has anyone else heard of this? Should I consider getting new header bolts? I know mini-madness sells locking header bolts supposedly for this exact issue. Thanks!

 

It's always a good idea to use new bolts in this application . ARP is an outstanding supplier and easily sourced.

 

I use locking header bolts which are reusable. Can be found here: http://www.mini-madness.com/index.as...ROD&ProdID=270

 

Thanks for the feedback! I'm defnitely leaning towards the locking header bolts now.

 

i also use the locking bolts from http://www.mini-madness.com/index.as...ROD&ProdID=270, and have not had one problem with them. Sure is nice not having to worry about a leak or loosing a bolt.

 

hogwash.....tighten them back up......i've had the stock ones on & off probably more than anyone and never had an issue....but Yes you should replace them.....ive just been to lazy......hehe

 

I didn't replace mine either...oops. I haven't had a problem though.

Well, the header came in. I Can't seem to get the springs compressed enough to thread the nuts on the bolts that came with the header. Anyone have any ideas?

 

scratch that. Bolted it differently.

 

Does anyone know the OEM part number for new header bolts?

 

07 13 6 800 269

 

I did re-use mine but buying new ones is a good idea.

 

I am also interested in the OBX/Random set-up. Any photos?

 

sorry. No photos of it in the car.

I also reused my header bolts, but have a 2nd set in the closet if the need should ever arise.
