3 inch catbacks?

So I need 3 inch catbacks and I'm not really sure about what to choose. I wanted corsa but I guess I'm not getting them because they are 2.5" or whatever. Help me

I ordered the LG Super Pro Headers and X-pipe combo or whatever and it's a full 3 inch x-pipe. I understand that the catback attaches directly to the x-pipe. I want the corsa extreme exhaust but it says that it is 2.5". Does anyone know if these two are compatible?

Unless you plan on running over 700 rwhp I know a local guy with a 03 Z and a katech motor with 600 rwhp and it runs low 10's with a corsa indy 2.5". The 3" barely fit are all clamp and a PITA to install for no reason. JMO. Go with corsa extremes and don't look back bud!

Oh BTW I had the same Super Pro X pipe header kit from LG as well.

I have the LG Big 3 cat-back on my '04 convertible and am very satisfied with it. The quality was good, install was fairly easy. It includes some new flanges to install to your X/H pipe to get rid of the 2.5" reduction if needed. If you have the LG 3" X-Pipe it's a straightforward bolt-on like stock!

I have the STAINLESS WORKS complete header and CAT back system. Everything after the collector is 3" and it fits excellent. Probably over kill for my heads/cam 450 hp mill but it performs and sounds friggen excellent!
