Whats going on guys? Im in the process of removing my facotry t45 out of my car because it seems to be stuck in 4th gear? Problem is, Im trying to get my factory H-pipe off, and the bolts for the drivers side between the exhaust manifold and H-pipe are EXTREMELY hard to get off and wont budge even after using an impact gun and torch. And then the passenger side I havent even figured out how Im going to get to those bolts next .... any helpful suggestions?

 

Are you getting them red hot? If not, they may not be getting enough heat. The other thing to do is to spray them down with PB Blaster (that **** is Awesome) and let it sit for a couple hours to break up the rust, heat em up again, and then nail em with the impact. If that doesn't work then...

 

^^ PB blaster ftw. tried to turn the bolts on mine, wouldn't budge. sprayed it down, tried a week later and it popped right off.

 

I would have started cutting before I came in here and posted in forums... cut cut cut buy new. Spraying with penetrating oil after heating works well also, something I used to do on diesels a lot.

 

Pb blaster and the torch works for me. If it doesn't, well, I have a big assed breaker bar that I use. 32" long with a 1/2 drive on it, not much can stop it. Worst case, just use the torch to cut the bolts out and put an aftermarket pipe on.

 

thanks everyone, ive actually been using liquid wrench, but ill try it some more because i was looking to be able to bolt the H-pipe back up for inspections. i figured while everything was torn apart id pick up a nice x-pipe as a grad present to myself haha
