Exhaust Swapping Catted For Off-road X-pipe

[90GTFIVO]

I'm thinking about swapping my current Bassani catted x-pipe for a BBK off-road x-pipe I have. Couple questions:

1. Will I notice a significant difference in sound?

2. Will the air flow increase all that much, resulting in a better option for my setup?

1. I believe it'll be much louder

2. Being that it is a Bassani set up, I think their cats would come as sort of a "High flow" type cat, so I wouldn't think it would be much of a restriction. Unless it had 100,000 miles on it and they were clogged up or something.

i just did the opposite with stock catted h pipes. took off the bbk h pipe and put on the factory part. not a big difference in sound. flowmaster 40 series out back and i believe they are the deciding factor on how loud it is.
