Yes its sad, I'm having trouble taking off my stock rusted POS exhaust to replace with a Helix.....I've gotten the muffler off but the bolts connecting the to the Cat are really stubborn...I've used heat and my superhuman strength but nothing...any tips?

 

put a big breaker bar on it and then kick the shyt out of it.

...works for me

 

You can get a product at Napa called PB Blaster. Pick up a bottle and soak the bolts in the future. This stuff works much better than anything else I have tried.

The other suggestion is to get as much leverage as you can. I find that a big enough breaker bar solves everything

 

PB blaster and Liquid wrench both work wonders. You can also try to find something that will slip over the handle of the wratchet to gain leverage if you dont have a breaker bar.

 

great ideas, but make sure u dont overspray onto ur o2 sensor!

 

I run into this problem everytime i do an install. Everytime its an easy job dragged out an extra hour b/c of rusted/tight bolts. Kicking the rachet gets the job done if you can placing a pipe for leaverage works best.

 

i get too angry and decide to pay someone else to do it.

 

yeah... as I'm sure you know: quick, sharp blows work better than constant pressure (trying to muscle it). you can even try to secure the wrench and hit the handle with a rubber mallet or something.

 

Those bolts can be a b!tch. Mine wouldn't come off till I took it to my mechanic and used his torch to put heat on them.

 

I duno how bad they are but most of these bolts i have seen are pretty destroyed by rust to the point that you can't even get a wrench to grip em so I usually just take my cars to an exhaust shop and have them torch the bolts off (they can do it without wrecking the flange) and then when you put it all back together get some stainless bolts/nuts and you'll save yourself some trouble should you ever have to pull it off again.

 

I had the exact same problem, I just took mine to a muffler shop to have them loosen the bolts. Better than trying to force it and break something.

 

Dam u beat me

 

Buy an corded electric impact wrench from walmart for 70 bucks. Up to 270FTLB of unscrewing torque

 

All good ideas. One more: My dear old dad always says soak the bolts overnight in Liquid Wrench. That often helps.

 

Liquid Wrench is always your friend.
