Certain points when driving the car and revving up or deceleration, it seems like it should back fire. Like it would sound natural. I don't like popcorn tunes but I'd like a little sound every once in a while. I was wondering if I gutted my cats and ran the catless tune on openflash, what all would change. For better or worse. It just sounds unnatural with no pop or sound ever. Thanks!

A) it is gong to be loud!
B) it is going to smell!
As above I would not gut the cats but get a catless header and front pipe. That way you can go back or just go with the cat in the front pipe.
