Suggestion

If you've never had it off before (and used lots of hi temp anti-seize when reassembling) you may as well just plan on breaking or cutting most of the bolts/nuts.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

I�m just not set up for it. I got them on jack stands. Removed the rear bumper. Removed the heat shields. first mistake- I tried removing the long bolts. Stopped once I realized they wouldn�t come out (bad design) Next I learned I needed to removed the six. It felt like they were moving but I believe they were just circling. I put it all back together. except for the heat shields and bumper. The hell with that knee busting and back spasms job. Ill pay my mechanic. i thought this was going to be easy. NFS.

POST 2Original post

PB Blaster overnight. Let them soak. Impact gun works wonders. If no Impact gun longer wrenches or bars. Replace all the nuts and bolts and use anti seize for the next guy. Dont give up. If you do go to a muffler shop not P car shop.

POST 3Original post

Use your jack handle(if you have a floor jack) as a cheater pipe for a breaker bar. (or a ratchet in a pinch) If you don't have an impact wrench, think about getting one. You'd be surprised at how much easier it can make a LOT of jobs.

POST 4Original post

If I were closer buy me a beer and I'll stop by. Maybe some other RL Member will offer up thats a little closer. DIY work on our cars is, while sometimes a challenge, its always rewarding when you getter done. Hang in there.

POST 5Original post

Muffler = 5 bolts and no need to remove bumper. It also helps if car hasn't been driven year round in salty winter road conditions. 😎

POST 6 / ORIGINAL POSTEROriginal post

So these three bolts are the culprit? I thought they were moving but almost like they were spinning. Not coming off.

POST 7Original post

Quotes source post: 15776989

Those three are nuts. If they're spinning then the studs or nuts are stripped/broke.

POST 8 / ORIGINAL POSTEROriginal post

I agree that�s why I hate to do it but it�s going to the mechanic. I take a beating after a while on the old knees and lower back. i took the bumper and heat shields off so I can at least enjoy a thorough cleaning in there. Can�t wait to get the Fisters on.

POST 9Original post

Northeast winters are brutal on the exhaust system hardware. If you've never had it off before (and used lots of hi temp anti-seize when reassembling) you may as well just plan on breaking or cutting most of the bolts/nuts. If your mechanic does the job, ask him to please use anti-seize (copper based/high temp) when putting it back together for either you or the next guy who tries to take it apart again.

POST 10Original post

I think the new Fisters will ease your pain.😎

POST 11Original post

I had a similar experience and have yet to get them replaced. Sprayed the crap out of everything with PB Blaster overnight, got the bumper and everything else off (not a big deal at all), and made no absolutely progress in getting the nuts moving on the brackets. The 3 bolts on each side for the muffler mounts came off super easy, which I guess is one good thing but if I can't get the brackets off, that doesn't really get me anywhere. Fisters still sitting in my garage. I bought a new full set of brackets/bolts since there is a 100% chance that the bolts will need to be cut off. My plan is to just let my local shop do it. I try to do as much as I can myself but there are some things that just aren't worth it.

POST 12Original post

And for the next time you (or anyone else) needs to remove them, have the mechanic reassemble them with the long vertical bolts with the heads downward, nuts on top, copper antiseize. With the factory orientation, it is impossible to remove those bolts to take off the mufflers from the brackets. If they flip them, it makes it an easy job. I suspect it made for easier factory line assembly, but it is one of those head scratchers when you do the service work. If they�d installed them the other way day one, it�d make later service work easier for everyone.

POST 13Original post

Quotes source post: 15776996

To reinforce this - the brackets in the picture (held to the muffler with two long bolts of different lengths), have studs on them. The studs are prevented from moving by spot welds in the bracket (if I recall correctly). Those brackets are bolted to another bracket that is bolted to the engine. You are removing three nuts from the inboard side of the bracket. If they are spinning, (in my opinion) your best bet is to replace the brackets. Some people press/drill the studs out and tack weld bolts on. I prefer to replace with good used parts. Personal preference only, both are equally functional. If you need a set, keep in mind the 996.1 and 996.2 parts are different and do not interchange. The studs are in different locations. I have a pair of each kind in the garage attic if you need them and can�t find them. Message me if you do. On one car I had to sawzall and grind my way to getting these off. What a hassle.

POST 14Original post

My guess is it could also be a safety issue....for the car following behind (in case the bolt drops out).

POST 15Original post

get this from Gert @ Carnewal with the car this far apart, coils and plugs too

POST 16Original post

Great idea (essential up here in the North). That being said, you can buy the same parts for a fraction of the cost on eBay or Rock Auto.

POST 17Original post

^^ That's a crazy high price when you consider you have to ship them from Belgium... Buy them locally and save some $$. I bought my Third radiator kit from Gert. as the exchange rate was excellent at the time, and I saved around $200 from what I could find in the States (even with shipping). There are things you can save some cash on but I don't think the exhaust clamps are worthwhile.

120 Euro? That seems crazy expensive for some clamps. Design 911 has a full set for $48. https://www.design911.com/Mounting-K...GT3/prod13006/
