alright i have a stock 96 mustang gt...i just bought a mac off road h and bassani cat back ive been waiting to have put on for a few weeks...well im talk to this guy tha works at a shop and hes saying i cant go catless because it will run to rich and mess up stuff like maf censer and some other stuff...and the exhaust will build up with black sut.....i mean i know it will probably blow some black smoke at first not having any cats.....i was just wondering what everyone elses input on this might be because i really wanna get this put on...but i dont want to mess up anything.....there saying they can cut it right after the first cat and weld the rest of my pipe on...so are they just full of **** or what?

 

anyone?
