Anyone got any thoughts on which is better and why? I personally hollowed my cat out, and it was obviously a pretty big bottleneck as the performance increase was noticable. Previously I'd considered getting a high flow aftermarket cat, but my question is: "Why bother?" It just seems like you're spending cash on something you could do yourself. Granted there are emissions differences, but as of last summer Florida no longer has emissions testing. Sound does reverb a bit in the hollow cat, but it's either gone away or I've become used to the sound. Other than that, what's the difference? Any thoughts/comments are appreciated.

 

good question i would like to know. i hollowed mine out also

 

just get a test pipe...and keep your stock cat for emissions

 

ive done the same... and wondered the same. still no one has proven that an aftermarket cat works better

Get a test pipe. Less turbulent, flows better.

 

I heard rumors thats its illegal to change your cat unless its bad....

 

who cares? It's not like anyone will know

 

Wont emmisions know?

 

Just keep ur stock cat....when you go in for emmisions just take it off Simple and ez!

 

Seems like most of you missed the point. I was wondering the difference, if any, in performance. Emissions isn't an issue for me, as Florida no longer has emissions testing. I've already hollowed my cat, so there's no need for me to get a test pipe. I'm simply wondering about the difference between the two, not how I can avoid breaking the law or beating emissions. Thanks for any input.
