HELP: Cat Deletion.

[CtGuy93]

I recently bought a 92’ mighty max. 2.4. And I’m trying to delete the catalytic converter. Just wondering if anyone had some tips to getting the right size piece of pipe. Theres a bracket on the backside of the cat flange and I’m not sure which approach I should take. Flanges or Ubolts? Also, I’m keeping the muffler. Thank you!

Is there a reason you want to delete the cat? If it's not plugged up it probably isn't hurting performance. While I haven't done it on one of these trucks, if you have a straight piece of pipe coming out of the cat, you can "gut" it. Jam a crow bar or rod in the end and break up the catalyst mesh. After its broken up, start the engine and rev it, and the pieces should come flying out. The advantage of gutting it, is that you don't have to modify the pipe. Just bolt it back together.

Hi and welcome to mightyram. As Giovanni has suggested, most guys will simply knock the core out of it but I'd be tempted to do it with the cat removed from the exhaust system first. You may get unlucky and have a fragment lurking in there and end up somewhere further down the exhaust like in the muffler. The rattle would affect your sanity.

The reason being is that the forward flange after the cat is cracked at the pipe and is loud as heck. Being that it’s old enough, in my state I don’t need to pass emissions or inspection and having a straight pipe will be the least expensive way to fix the noise. But my problem is the design. I did some observations and head scratching but I think I’ve come up with some solutions. I’ll report back with what I’ve got! Thank you for the welcome!

OK that explains everything. If it's no longer required for emissions and it's already toast, there's not much point in investing in a new replacement cat.
