exhaust install problem

Today I started on my TBE/uppipe installation. So far its been easy but VERY time consuming (I spend the better part of 9 hours working on my car today). Now there is one bolt I simply cannot shake loose. The bolt thats holding down the downpipe bracket will not come off. Does anyone know the best method of getting this bolt off? After this I have to swap the uppipe and exhaust then put it all back together! Also, should I get new manifold gaskets??

Liquid wrench is a nescesity on this project. You must use it on the bolts or you will be very frustrated trying to get them off. I dont which bolt your talking about exactly but i had trouble with one of the bolts supporting my DP also. Just use alot of liquid wrench.

1. Best method of getting tough nuts/bolts is to use a LONG LONG LONG extension. Doesn't have to be anything special... even a long metal pipe would work. Just stick the handle of your ratchet into the pipe and it should give you enough leverage and torque to get that sucker off.

2. Like they mentioned above, use LOTS of Liquid Wrench, PB Blaster, or WD40

3. New gaskets are ALWAYS recommended if you are taking apart pieces that are exposed to lots of heat (engine parts, exhaust parts, etc...). You may be able to wing it with the old gasket on there if your car is fairly new.

I'd be a little careful with too much torque on bolts that have been in a high heat environment, they tend to snap easier.

You can also (carefully) heat the housing around the bolt with a hand torch. It will expand the housing and help loosen the bolt.

New gaskets are always recommended.

.. I think I know which one you're talking about. My friend was helping me and ended up hack sawing it off. Only damage was to the stock DP.

PB Blaster is also the shit. We buy it by the case on the farm (we have mostly older equipment).

PB blaster, I always wanted to try the styrofoam cup test thats on the label, but never had a cup around when I needed one, great stuff though.
