Yes, the top bolt of the cat flange should have a welded nut. The bolt however will back out just fine. The bottom two bolts you will spin the nut off as the studs will stay in place, bottoms are pretty easy to get at. Takes some clever arm routing but over all pretty easy. I also sprayed mine with WD-40 the night before just in case.

Cool thanks, I've gotten to the point of remove all the nuts and bolts but I can't get the cat and pipe out of the car lol. The bottom two studs are still on the adapter and the exhaust is getting stuck on the hook piece near the muffler. I'm starting to consider dropping the entire muffler... Is there another way around it?

I disconnected the cat pipe from the U-Pipe and got the u out first. Then i let the cat fall so the cat was actually facing toward the ground. With the cat facing the ground i pulled it straight back and slightly downward. Took a little jiggling but it does come out. Hope this helps

Does that mean you hammered or cut these studs off? Because I can't twist the cat at this point

Once i disconnected the u pipes my cats came out really easy, However if you have the stock muffler still on, there are some supports that connect the muffler to the cats that need to be removed as well.

I guess it's Christmas for everyone. Mine came in yesterday and will be going on this weekend. I like the idea of using High Temp paint... I may try that. With the unrestricted flow there shouldn't be any temp increases, I would think you'd see a decrease.

Ok, so the pipe clamp doesn't fit the bypass pipes since the bypass pipe end is a larger diameter than the original cat pipe diameter. SO, how the heck is everyone one getting the pipe clamp back on with the new bypasspipes? I put my cat back on the driver's side after I started up with a kluge fix with the bypass pipe that was releasing quite an exhaust leak. Anyone have a good fix?
