Hmmm, power delivery would be a lot better IMO if the cat was deleted. Imagine that, no more restrictions. May sound better as well. I would take a free-flowing exhaust any day!

However, there might be drawbacks when the cat is deleted:

1) Maybe too loud for some.

2) The cat should be re-installed when it's time for a smog check.
