Just how loud will this be? I decided I will just be having a shop install them because I wont have the time to do the install for at least another week or two, and they didnt have the hi flow cat for this setup in stock, and said it would take 4 to 5 days longer than what they already stated (3 to 4).

Will I be deafened compared to hearing the stock exhaust?

Also, where could I pick up the cat to bolt in place of the ORP for relatively cheap?

 

It won't make it much louder. You'll hear more "under the hood" sound while driving (not as quiet inside anymore), but overall, not hugely louder. A small difference.

Hmmm, well alright thanks. I was under the impression that it would be a lot louder

 

Hell, mine isn't much louder than it was stock, even after the CC305, ported heads, MAC headers, and ORP. Still running through the same Flowmaster exhaust.
