How will my catalytic fare against my 2 step rev limiter? i can get some nice nasty pops/bangs coming out the muffler so there is some good amt of pressure going through the exhaust system. Is/will this eat away at my cat???????

 

whatever you do, dont use ignition cut only for the two step... you risk blowing your cats to peices!


if you use FUEL CUT for the 2 step, you should be fine.

 

but with just ignition cut you get some nice amts of fuel to blow up and make lovely noises and flames
lol.
I actually am cutting both fuel and ignition equally right now but I still get some nice loud bangs/pops with some fuel clouds sometimes.
