HKS I think it sounds better, and bling bling carbon on the back end. But if you are thinking about cost being a problem then go with the turbo xs you will get better gains from the turbo back over the catback system. The second the "don't get the HKS downpipe, cuz it is not a bellmouth and for a lil more you can get the helix unit, which is. This is important if you are going to upgrage your turbo in the future because the helix type pipe will help the wastegate breath (ie. little to no boost creep)

I would go with the HKS Catback, I'm going to be ordering mine on friday!!!!!!!! I can't wait!! Yes yes we all know the HKS downpipe isn't the best, but i'm short on money, and I have one, it's a pretty good deal for the money. Anyways I'm going to have the mechanic at my work to open up the wastegate side by welding another pipe on it. So it'll be better than a normal HKS downpipe. HKS makes the most power in the catback systems.

Does the hks replace the mid pipe like the txs does?. If he bought hks with the helix downpipe would that make it a turbo back? I am debating between the two also, but i want to do the helix up/down pipe and hks. I just want the most power. Everyone says that the hks produces the most.

Hks catback with helix dp would make it a turboback.

Dyno proven to have the DownPipe that shows the largest HP gains then any other DP on the market!! Better gains then the TXS also!
Something to think about....

Yeah the HKS is a super nice exhaust and offers really good HP gains for a Cat Back too! 
I like the way that the Carbon-Ti looks and sounds! That thing is sweet to look at...

Personally, I would go with the TXS. That's the one that I am really looking at. It sounds better, and you will have a downpipe that is made by the same company for their catback. TXS also has a stealthback which runs from the turbo back to the axel and you can put just about any muffler and tip on it. The HKS only has a titanium tip. That muffler has a carbon fiber wrap around it, but it still looks bad a$$. Hope this helps!

Basically its a hks catback but taking off the axleback and swapping with a rfl from txs... wondering if it would work for both of us
