Help removing muffler bolts
 

I was wondering if there are any tricks to removing the bolts on the muffler?

Called a torch!

PB blaster, wait 5 minutes, and use a 1/2" wrench with breaker bar if necessary. Thats what worked for me when I did my sway bar install.

im going to have to try PB blaster, unfortunately i dont have a breaker bar, just a 14mm spanner

I was having trouble too but my dad came to help. He put a wrench through the other one and boom it was done. Spray some WD40 and make sure u have an extension to creat leverage.

You can bang it a few times after you apply your favorite lube... (Pun intended? Lol)

Yep PB Blaster works great. I sprayed mine on while the car was cooling and about 2 hours later, sprayed more and got to work. I was able to get 3 off, but for the 4th, I was so physically exhausted because I didn't have a breaker bar, I called my dad in for some fresh muscle and it popped off and all downhill from there. The most annoying bolts for me were the right exhaust hanger. You have to get it at a weird angle with an extension so you don't have must room to work with yet alone break the bolts, but again PB blasted it and with some slight of hand, it came off. Oh and watch your eyes. My dad and I both took bolts to the face when trying to put them back on. Painful. Good luck!

I did my exhaust at 27,000 miles which is lower but if you have a higher mileage car, you may need the torch.

im doing mine at 30k

it looks like im running down to the store to buy some PB blaster today

so far that seems to be the product everyone recommends

If you still have trouble with the PB Blaster, let it sit longer. Let it soak overnight if you have to.

If your jack has a two piece handle, you can use part of it as a breaker bar if your ratchet fits inside it. I've done it in the past. I've also very carefully put my jack under the wrench and slowly carefully used the jack to turn the wrench.

If you have an air compressor, an 800 ft-lb impact gun works wonders. Even so, use some PB blaster. That stuff is great.

I recommend buying a breaker bar. It's one of those tools you will use over and over. Next time you are at harbor freight, they have a 36" for $10. Money well spent.

Absolutely. It will become your new best friend working on the car.

Piece of pipe is cheaper

+1 on the breaker bar, used it when i put my AAM ti-short tails on

1/2" breaker bar and a piece of pipe to slide over it if u need extra leverage. Worked like a champ.

Also. If your not bleeding. Your not doing it right. Lol

I used a grinder and cut a couple of mine off. They were on so tight that the 2 of the bolt heads rounded and 2 of them just snapped off.

Use pb blaster! Say bye bye to the struggle and even the demon bolts on the cats came off with ease!

Don't do this. Using air tools on the exhaust is a good way to damage the O2 sensors due to the vibrations. While the vibrations may not make it all the way from the muffler up to the front, with our expensive O2 sensors is it really worth the risk?!

:iagree:

I love peanut butter blaster!!!!!!

I had less than 22 thousand miles and have never driven in the rain on my car. I sprayed the bolts with a penetrating oil and let it sit over night and my bolt heads still stripped.

I guess some are just super tight. But changing out the exhaust with a cat back system sure does make the car more fun.

Good luck!
