I've got a 3" Dynomax cat that doesn't offer the same 4 bolt flange that my stock 85 cat offered. For a couple years it stayed put where it was supposed to be so I never worried about it, but this weekend it seems to have dropped and it's scraping everything now. Has anybody else had to do a custom mount to keep their cat up? I don't want to drill into the floor, so any opinions (pics would be great too ) would be very much appreciated. Thanks.

When I put in my catco 3" cat, it didn't match up to the flange either. One bolt would and the other one wouldn't. I just put one of them in and tightened it down really good. I haven't had any problems yet with it...

 

My cat doesn't have any bolts. Its a 3" universal cat.

Hey Jim, I'm taking mine in to have a custom hanger put in. One of my clamps is within two inches of the ground. I'm going to need them to tuck the exhaust up and then secure it in place. If you like I'll get some pix for you once it's done.

Pics would be great. I got under there tonight, and the pipe where the intermediate pipe goes into the cat (ala my reducer piece) was loose. I pulled the cat up into place with wire (nothing like cob jobs) and tightened the bejesus out of the clamps. So far so good, but I suspect it won't be long before it starts to fall again. The problem is, I cut the intermediate pipe right next to the bend, so there's very little pipe inside the other pipe, so it comes loose too easy. Hopefully soon I'll get around to bringing it to a muffler shop so they can bend me up a custom exhaust. I want a 3" catback with a resonator right behind the cat, then over the axle, split and 2 pipes in the stock location, just like SLP's loudmouth.
