I have an extra stock cat that's clogged. I want to gut it and run after I get an ecu. I currently have intake and DP. Do you think I'll have a problem with boost creep or not? I've read a gutted cat won't flow as well as a midpipe. I have stock cat back right now but plan on getting a racing beat dual tip. Any opinions are appreciated.

 

I doubt you'll get creep, because the stock pipes aren't 3".

 

bump. Any more opinions?
