I just bought a Magnaflow cat to go with my Magnaflow Cat back system. Was wondering if the performance Cat will make my car sound and perform better then my stock -shot- Cat. I'm positive it will but, a estimate on how much louder and better would be nice. And maybe some tips on how to successfully remove my old cat from the rusted Y pipe.

 

i'm in the same situation here... i'll be putting mine on in the next week or two.
