Both stock head pipes are leaking throw a round hole near the finned flange at the head.

I was wondering if theres any quick way of fixing it? welding?

the mufflers I have on the bike have grown on me and i was wondering how easy it would be to replace just the head pipes for new ones. Can i uses the ones on Mikesxs and if so which ones?

heres a pic of the bike and mufflers

stock head pipes have inner and outer tubes, the hole is there to allow for condensation while the machine is heating up, theres also one in the bottom of the pipe to allow moisture to escape. If you have blow by in the inner pipe it will come out the hole. I would replace the pipe with mikes 07-0757 head pipe. Although you might need to shorten the pipes to fit your mufflers.

Well, you can use an adapter to connect the muffler to the inner pipe available at most auto supply stores:



Here's what the inner pipe looks like:



Here's how it works:

I still don't have my edit back....

The adapter is part number 548520. It's a 1 1/2" to 1 3/8" adapter.
