I have a nitrous kit on my 98 stang, and when I went to the 125 jettings I destroyed at least 1 of the Cats. Before i go to get it fixed I need to have a plan on what do.
I was thinking that since I have to pass emissions here once a year I could do electronic cut-outs. I know it would sound terrible, but I could bypass the mufflers/cats and save myself 300 dollars everytime I spray on new cats.
I was also thinking I could get an off-road X or H pipe. LASTLY I could just say screw the cats and have straight pipes to mufflers and then they have turn-downs. The problem with this though is emissions. When I went last year they just plugged it in (my car wasn't even running) and they said "okay you passed" after like five minutes. I was wondering if they would be able to tell that I no longer had cats.
So it's basically either cut-outs or cat-less exhaust. I need your guys' help and advice on what to do. I can get exhaust custom made - and money isn't an issue. Thanks a lot.
