100 cell high flow cats

Fast Intentions sells the lead pipes with cats but I believe they will only sell that section to customers that have already installed their cbe. They don't sell individual components as far as I know. I doubt there is any clearance issues. I'm not sure about compatibility, someone else may have a better idea. I already have a fast intentions cbe system. All that I need to do is cut off a section of the lead pipes and have the new cats welded in. Pretty simple.

This is where I stumble a bit. The times I used to have to go to muffler shops years and years ago when I lived in upstate NY (because of all the salt on the roads), plus the times I changed my own exhaust parts (or trying to diagnose leaks) inching around on a garage floor on my back, taught me that this is an area of the car: 1) that I don't want to deal with, and, 2) requires exact-fitting parts. I once ordered a cbe for a car I owned from a company that insisted it was designed for my car, and lived with it banging against the frame for a couple of years in one spot, and the muffler hanging much too low in another...only to find out that they had sent me the wrong part.

When you say, cut off a section of lead pipe and weld in new cats, I wonder, what happens to the flanges that are supposed to mate together...precisely? I see on various websites that these Z-specific parts are often tig-welded, which is far beyond what is done in muffler shops -- they just use oxy-acetylene torches. If parts are welded instead of mated/bolted...especially if it's in a location not supported by hangars...you run the risk of cracking said weld down the road.

I think you're overthinking it. The 100cel cats are small.. the shop will just cut out a section of pipe and tack the cat in place while the exhaust is still on the car, then take out the pipe for finish welding. It should fit fine when they are done... they literally do stuff like this every day.

Thanks for that. The other thing I'm wondering, is if you move the cat back, it won't be able to reach operating temps, no? Florida isn't one of those states that tests, but this would be a major headache for those states that do. Plus, even with the 100-cel cats, you'd probably have stink to tolerate if they don't get hot enough.

You're right...I'm overthinking...
