Cutting off my cat and leaving my dual exaust

[Brendan Mangiulli]

If i cut my main cat off my truck and leave the resonators on the y pipe on, will it hurt anything i want to make my truck have a deeper tone and a little louder. I have a heartthrob deeptone dual exhaust on theyr already feedback is appreciated.

May raise hell with the 02 sensor, may need an eliminator.

You have 2 rear cats.... you can cut out the furthest BACK cat with no problem...



IF you remove both, you will need an XCAL tune to turn it off.....



Also if you have emissions testing, you know what will happen..

thanks but ur not talking about the tiny resonator on the back of the exhaust because i already have a catback exhaust system that i replaced it with. your talking about the bigger cat in the middle of the truck?

The ST has 2 bigger cats in the middle.... look there should be 2
