    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

  • Returning Visitors

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

I just bought a sweet 4 to 2 exhaust from a guy, chrome and all in excellent shape, and started to take my old stock exhaust off and low and behold the idiot that I am cross threaded the #2 exhaust bolt on the top side. Now it wont even thread in. I tried chasing the threads with a tap and I honestly don't think there are any threads to chase. Is there anything i can do. I don't really trust myself to drill it out and re tap it. Any ideas that wont result in me paying big bucks to a machine shop to fix it?
 
Have you looked into purchasing a 8 mm X 1.0 pitch Heli-coil kit?
After you drill it per the instructions, add two of the inserts.
It is best to also apply red lock-tite to the threads of the inserts when you instal them.
You stack the inserts one over the other . You have to insert the first one deep enough to allow enough room for the second one to sit flush with the exterior.
Do not leave a bolt in the inserts until after the lock-tite has dried.
DO insert a test bolt BEFORE it dries to make certain that they are in sync and quickly remove it.

Something tells me that it's NOT an 8 x 1.0 kit he's looking for. :-k

Not sure which one it will be, but it's either going to be an 8 x 1.25mm or 8 x 1.5mm.

.
 
Correction as no one has posted for certain, just get an 8 mm by whatever the stock pitch is Heli-coil kit.
Bring a good example with you when purchasing. Standard (coarse) pitch for an 8 mm bolt.
 
I heli-coiled more than 1/2 of my exhaust bolts.
never thought to double-up.....
After the 1st one, they are easy to do, hard to screw up.
just follow directions.
and change the gaskets !!!
