02CL-TypeS

I got a set of XS Power headers for my 02 CL-S that are supposed to be installed tomorrow. I went to my local hardware store to get new bolts/nuts/washers in a higher grade. I've read that you are supposed to get 10x30mm bolts and nuts/washers.

I'm so confused though b/c I took the hardware package they sent me with the headers and the bolts were not 10mm! They were 8mm and 35mm long! WTF? I have an appointment tomorrow to get these installed and still don't have the correct bolts

BTW, do I need 1.5 or 1.25 thread?

The shop that installs them should be able to replace them for you. I can't remember the exact sizes for them off hand. Do a quick search you may be able to pull up some results.

10mm fit better and fill the entire hole. Anywhere from 30mm-40mm are fine. Thread doesn't matter as long as the nut matches. You'll want 9 of them.

thanks guys. Anything I should tell them before installing the headers since thye don't come with instructions?

10mm X 1.25mm and 35mm long.

If you can find lock nuts, I would get those. Get the ones made for exhaust. (not nylon locking)

Have them wipe down the pipes with brake cleaner so when they start it up, the pipes won't be stained with grease/handprints.
