i have been debating about an X pipe with or without cats for sometime now. I have read some reviews that some Mustangs with slight built motors have destroyed high flow cats. Some claim the insides have been blown out. Is this a real concern? The only reason I am considering cats with the X pipe is because of the smell issue I keep hearing. I know my wife would complain if it smelled bad. I have a 2004 GT slightly built. Any opinions out there on this issue of the inside of cats blowing out?
