Default Just ordered a Invidia Q300 Catback, What else do I need to hook it up?

Hey,
I just bought an Invidia q300 catback exhaust for my 04 WRX and I'm wondering what else I'll need to hook it up?
I currently have a full Turboxs RFL system with a high flow cat (cat is gone though).
Would the invidia cat back hook up to my turboxs down pipe?
I'm about to buy an invidia down pipe anyways because I hate trying to get all of the bolts in/out of the Turboxs down pipe, and I don't like how it hangs down so low.

So if I have the invidia down pipe and catback is there another piece I need?

Thanks.

TurboXS exhausts are PROPRIETARY length. You MUST buy the conversion pipe to make it work. Why do I know this? I have the TXS downpipe + conversion pipe + catback on my car. The pipe is $100ish and available through any TurboXS vendor. Then your catback must have a flat flange in order to work.

What the guy above means it's called a turboXS catback adapter. If your exhaust tapers to 2.5 and has that stock looking donut space you need a 3 inch downpipe to catback adapter. You can find this on importimage and jscspeed.

You were right. I just got the cat back and it is almost two feet too short from reaching the turboxs down pipe.

Anybody know if I just buy the invidia down pipe will it hook up to the invidia catback? Is the invidia down pipe longer then the turboxs?

Please respond asap if you know for sure.

Thanks.

I knew about the downpipe, but what about about the axleback?
