CAT SIM/CAT Delete...Where?
Anyone know where to find a direct "plug and play" SIM adapter for the Cat-Delete setup? Somebody mentioned before about some Viper brand SIM, but heck if I can find anything. I found a generic one on ebay, but I'm not rollin the dice on that one.
I've found a ton for the EVO out there, but nothing much for any euro's...

A buddy of mine will do the work for free (trading favors) if I can get a SIM in place so the check engine light isn't goin crazy.

the 'spacers' that you use for this mod are called spark plug anti-foulers...you buy 2 of them for every O2 sensor you want to mod...take the two foulers, screw them together, then put one end in your exhaust and the O2 sensor in the other end...you are now done
you can pick these up at any auto parts store pretty cheap...

If you are talking ZERO gain when using a high flow cat vs. a stock cat, that makes ZERO sense. The stock front cats are pretty restrictive. Freeing that up has got to make more power.
What does everyone thing? How can there be no gain?

I assume you are talking about the stock front and rear cats vs. running straight pipe around? One thing I was told was that if you just run a straight pipe (up front) you could "lose" hp and tq. There needs to be larger diameter tubing in place of the front cats, which I assume is for backpressure.

this statement does not make any sense, you do not get more back pressure from larger diameter piping, you get less...

I agree and said the same thing to the guy at exhaust pros. He attempted to explain it but it seemed backwards. I'm sure there are articles on it around. He showed me pictured of other cat delete systems that were "straight pipe" and they all were at least double the diameter of the exhaust pipe for "backpressure". I dunno?![Confused](https://mbworld.org/forums/images/smilies/confused.gif)

I dunno. They're the ones that talked me into going with the high flow cats vs. straight pipe. Sounds like after the dyno run it was good advice. I would like to think there is some method to their madness.

That makes no sense. You sure as hell won't make more power with a high flow cat than with a straight/test pipe.
