So I'm doing the TII swap and I'm slowly piling up parts in my living room. I started thinking about the exhaust and the difference between the TII and NA.

From my research, it seems the everything except the diameter is identical from the cat and back. So theoretically, I could bolt up the N/A exhaust if I needed to. But I'm wondering how it looks from the Turbo to the cat?

What piece do I need to get the N/A catback to link up with the TII motor?

I am planning to upgrade to the Racing Beat unit when I get the cash.

jspec downpipe or stock turbo precat and the stock pipe that connects to the cat.

you can snag a downpipe off ebay that will bolt to the stock cat for like $100.

Thanks dude. The only eBay downpipe I was a le to find was 200. I'll keep an eye out for it. Any particular brand you may suggest if I don't go the eBay route?

i got a custom downpipe in the for sale section that goes from the turbo all the way to the cat back.
