Thanks. Kinda got my hopes up that I could get ride of the rusty rattling cats with no side effects. Should have known better!

Yea , hacks rarely prevail in the end. But if you use your head, many have done well doing it the right way and end up with a good job done for nothing (if you can turn a wrench) with extra cash in their pocket. Yep, you can make a little bit.

So what you did was drill a hole on these item so the nipple goes through and use two of them together to make them more "spacey". right? is this the right thread 18mm product for a f150 1998 4wd 4.6L?

If you found you were wrong on the back ones, could you please explain? Thanks

Is that to say running only a front cat will be within specs in CA and NY without visual inspection?

rgfoote

with 2 cats on each side, where do you put the anti foulers? front or back cat?

Turbonut

Normally the foulers are placed in the downstream O2 sensor as that's where you're trying to fool the computer in that the cat is working fine.

If you have two properly working cats, you don't need to fool the PCM....

Missouri doesn't have inspection stations
