Good 3.5" or 4" catback? quiet & flows well

So Im going from 363rwhp to 550ishrwhp and need to upgrade my exhaust.

What are the options out there for 90MM or 3.5" or 4" catbacks?

Any pics of the routing?

Theyre all loud at that point. I think your best bet for quiet would be to buy a domestic muscle car muffler from summit(ie) and have it custom built. Otherwise I know the apexi GT is a big one.

exaust

This is an HKS 4". I spoke to Random Technology about a cat for this ( I would obviously have to cut a section out of the piping). They have a 4" cat which is about 10" long. Will be doing this when the time comes to install.
P.S
I have 1 available for sale.
