Hello BB'ers. Tonite's discussion concerns exhaust system replacement. Seems I need all components from the Cat back. However, I do not have a torch, except a propane job. I can borrow a sawzall and purchase some metal cutting blades. In addition, I have a dremel tool, but would also have to purchase some cutoff discs.
I'd like to purchase the Volvo kit and replace things myself, but I'm afraid I'll have trouble. I'm wondering if I should just take it to a muffler shop. I'd love to do it myself but I'm afraid I might be biting off more than I can chew. I suppose I could beg the local Indy to do the work for me if I'm desperate. I hate bringing parts for them to install, however.
If you can offer any tips for a DIY'er, I'd appreciate it. If you can inspire some confidence that would be helpful too.
Thanks,
Marty Wolfson

Thank you everyone. I will keep you posted on the progress of the job. Sounds like a MW do-able project.

I have used the Dremel tool with a ceramic cutoff wheel for this job and it has worked great. I generally cut the clamp at the first muffler and then just throw the whole mess out from there...no more cutting after that. In cases where I can't get that first muffler off the cat, I use the dremel to slit the muffler sleeve and then peel it back with a hammer an chisel.
All of this is not so bad if you are going with the cat back replacement.

It is a pretty easy job once you get the system disconnected from the cat on back. If you have a saw, then you can cut it off. I always purchase the muffler patch stuff so I can use the material in the tube in the joints. I think the hardest part is getting the "rubber band" that holds the first muffler up attached. I finaly figured out how to do it with 2 screwdrivers. I purchase the entire kit from FCP, then lay it out on the pavement next to the car so I can visualize how it comes other. Then I attach it all, but I don't crank down the pipe fitters until I have everthing lined up so it doesn't clang around. Then just tighten everything up.
Budda-bing budda-boom.

Hi Marty,
This job can vary a lot depending on the rust due to short trip driving or your road salt. I've done it a half dozen times at least, on 240s a lot older than a 93, so I can tell you to go for it, without hesitation.
I've used both the Starla kits and the Volvo kits. The Volvo cat-back kit was absolutely the dreamiest under car exhaust work I've ever had to do. Everything fits right and the kit is complete. Caution here, I've just read a couple accounts on the forum where the Volvo kit is now an over axle scheme. I have not tried that one yet, and don't particularly want to.
You should be able to snap the clamp bolts with a wrench, or if badly rusted, large vise-grip pliers. Torch not necessary. Worst case; hack saw. The only clamp you need to remove is the one in front of the resonator, then just drop the whole assembly as a unit. I usually wind up coaxing the pipes apart, once the clamp is gone, with the help of the two pound maul. Anything with a bit of inertia will move the pipes apart until it drops. That is the most difficult part, and not bad at all.
Then, assemble the new parts loosely on the ground. A bit of balance required, but you can guide the front muffler onto the cat pipe with an arm outstretched holding the axle pipe, holding the rear muffler up on your chest. Once connected, the pins on the rear muffler are locked into the hangers, and the second most difficult part is left.
Getting the ears on the front muffler (resonator) hooked to the bracket under the car is tough, unless you can boost the muffler toward the floor with a jack. Then I use a pair of large screwdrivers to aid in stretching the big hanger o-rings over the resonator's ears.
The Starla kit goes on the same, and it does fit well too, but when you pay close to half of the dealer price, the oohs and aahs just are not expected. I wish I could be more specific about the differences.

Art, Thanks for the reply.
You said: "You should be able to snap the clamp bolts with a wrench, or if badly rusted, large vise-grip pliers. Torch not necessary. Worst case; hack saw. The only clamp you need to remove is the one in front of the resonator, then just drop the whole assembly as a unit".
I take it that so long as I don't have to remove the Cat, then a torch is not necessary as that is the only item that is bolted onto the exhaust flange. Is this correct?

Hi Marty,
Pardon me. I read "from the Cat back" to be the parts behind the cat; those I've referred to as a "cat back" kit, beginning with the front muffler. Really only four parts are usually replaced; two mufflers and two pipes.
Whenever I remove a cat, I'm in for a session with the Dremel tool as a means of removing the rusted hardware. Though I have oxy-acetylene, I work under the car on jackstands, not a lift, so it simpler for me to use the cutoff disks with the rotary tool.
Still not a daunting task, but I'd take two "cat back" jobs to equal one including the cat.
