Why are you using simulators? Spacers work just fine

yup, and most of the time the simulators either don't work, burn out, or mess up your O2 sensor, which is not something that you want to be replacing unless you have too...they are not cheap

Never Heard Of Spacers, I Keep Getting A Check Engine Light For My Cats, They Are Hollowed Out So I Need To Get That Check Engine Light Off. Will These Spacers Take Care Of That And Were Do I Get Them? Thanks So Much

Scroll down to CEL eliminator. They work on benz, I've verified that myself. Why are you removing the cats? I just did dyno research and found that removing the cats doesn't do anything. On my best dyno, I performed the same as with all 4 cats on, and on most dynos I actually lost about 4hp with the primaries removed.

"Not really a simulator or fancy electronic box. Just an adapter to move the rear (downstream) O2 sensor out of the exhaust flow more to keep the check engine light from bugging you, should it be on for some reason :-/"
