Muffler impossible/difficult to remove? - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Autocon · 07-31-2014, 02:44 PM

So my buddy and I tried to remove my FRS muffler last night to install my new Nameless Axleback. There are 2 bolts you have to take off and we couldn't get a single one of them to budge, not even slightly. I felt like if I could even pull any harder to try and get them to loosen I would have pulled my car off the jackstands.

Has anyone had this issue? We don't have any power tools, just hand tools. Any tips for removing them? Since we couldnt even get the first easy accessed bolt off I dont know how we would ever get the second one which isnt as easy to get too.

I know I could take it too a shop, but I kinda wanted to do it myself and I would rather not pay someone 40 to 50 bucks to, for the most part take off 2 bolts :/

lots of PB Blaster

WD-40 and a breaker bar. There's been a few posts with people having the same problem. Mine was easy though. Didn't even need a breaker bar.

WD-40 and good ratchet. I ran into the same problem but WD-40 freed it up. Still required a good amount of force with just a ratchet

Suggest loosening while not on jack stands if you can...leave it on the ground until you break them. PB blaster will probably all you need though...stuff works magic.

Damn, perfect thread to view at work before I head home to install my Nameless AB. Question to the OP, what was the mileage on your car?

also loosen the bolts while car is planted sounds like a good idea, ill try this.

good luck to OP

I had to use a breaker bar and my car only had 4800 miles when I was installing the exhaust.

J_kennington · 07-31-2014, 03:08 PM

There's no reason to lift the car at all for an AB. Even my 300 lb friend did his without lifting it. Keep it on the ground, use a breaker bar. If you don't have a breaker bar. Rip a fence post out of the ground and use it.

WD-40/PB BLaster and MAP Gas torch.

Seriously invest in a map gas torch. Can't tell you how many times it's saved me with broken exhaust bolts. Best 50 bucks ever spent. Especially if you like to burn things LOL

Also 2 Piece Floor jack handles make excellent breaker bars.

Or if possible use the double wrench method.

My exhaust came off at 22miles, so i had no need for any of that -- but wd-40 and pb-blaster is very useful.

Had to use PB Blaster and a torch for mine as well. This is after only 5 months too. I replaced the bolts with SS ones and used some anti-seize.

Sportsguy83 · 07-31-2014, 03:22 PM

If the car is lowered, it can get impossible to do it without lifting car.

Shady195 · 07-31-2014, 03:23 PM

My old man used to rag on me about using anti seize all the time. It took a few knuckle breaking moments that could have been easily avoided had I used anti seize... I now use it religiously.
