How much HP gain you think I would get if i hollow out my cat?

I went with an ORP.
But you'll see some gains and definetly a difference in sound. At least with my ORP, it was a whole new sound!

 

You won't see a very big gain, but hey, every little bit helps right?
As far as sound, yes you will hear a difference. Not only will you get a deeper, more gutteral sound from the engine, you'll get this rasp that will bug the heck out of you.

 

mione is guttedand i have a flow master....i get tons of compliments on how good it sounds...I don't have that rasp sound.
