Hey guys, it's been a while since ie been on here I'm not sure how many I the same people are still on here.

Anyway, I planned on changing my exhaust and decided to irritate the neighbors by cutting my exhaust off just after the pre cat O2 sensor, eliminating the cat, post cat O2 and flow master. It's very loud and it sounds amazing.

Without the post cat O2 sensor it seems to be running very rich and burning 7-8mpg not to mention the CEL. I tried to order the O2 SIMM from fastman, but he said he has been out of them for months and isn't sure when/if more will arrive.

My question is does anyone know of another company I can purchase one from, does anyone have one laying around they never used that I can buy, or is there another way I can fool the computer to get my mpg back to decent (was 11-12) thanks in advance!

Also I plan on putting a high flow cat on so I'd still like to do some sort of fix because I hear our PCM doesn't like the high flow cats either.
