hey whats up i was just wondering if anyone has tried gutting the cats stock appearance but they look to be pretty big in size so anyway just wondering imput

Not that I know of. It's better to go to test pipes being that the stock cats are very heavy.

I know of several people who have done it but I would rather just spend a little extra to get some resonated test pipes

you can do it, but i dont konw how much it would help.. you will create a very turbulent flow through that area

Only gutted cats I've hear about are the RT Cats that started the process on their own :dunno: Invest in some test pipes....
