Upgrade your downpipe and exhaust at the same time, the stock downpipe is very restrictive. Go 2.5" from the turbo back, use mandrel bends, and if you insist on a muffler go with a glasspack or a muffler that you can see through one end out the other.

On my Caddy, I used a 2.5" PP downpipe. When I took it to my local exhaust guru, he suggested a 2.25" system with a large magnaflow muffler. he said 2.25" was the max. size that would fit easily, and was way larger than the engine actually needed. What I noticed is that the turbo spools much earlier than before, and the sound is sexual.
