I tried to search. But what size is better for the stock ko3 turbo? My mods are forge dv, eBay front mount intercooler, Neuspeed catback and intake, ecs n75 race valve, and a stage 2 tune.

What size is your cat back?

I personally think bigger is better when it comes to downpipes. 3" is my vote

They work great. Just don't use the gasket or bolts they supply.

3" ftw, Ebays are cheap and fit well. I had one and was just fine, as mentioned though, dont use the gaskets or bolts.
