yeah, the 3" DP is a big help when it comes to bringing out the turbo whistle. plus it is said to give another 5-10 HP. i know i felt a pretty big difference. intake makes the turbo a little louder, but not much. the more pipe you have, the quieter the whistle. something else i'm probably going to do is get thicker insulation inside the cab, which will drown out some more of that exhaust sound too. Oh, and the way it's set up, i can still hear the turbo whistle doing 70 mph over the radio and road noise.

What's going to make that engine run great is a nice warm block and the coolest air you can get without cooling the block too much. Most of the time the air isn't going to be TOO cool. That's where the intake and exhaust come in. Get an intake that can move all the air you need then address expelling that air. Opening up that downpipe is going to decrease your EGTs and subsequently temps upstream of it. Those things should help with HP and economy. Plus the sound is wicked awesome. I did my downpipe early this week. Took like an hour. One cut with the sawzall and old one was out. Two cuts at the firewall seam and a slight bend and new was in. Voila!

You could do a fake cat for looks purposes.
Some guys just gut them out and stick them back in.
The Down pipe will improve efficiency of the motor, thus actually making it cleaner.
Guys ever wonder if the 198 T-stat was put in cause the DP caused such higher EGT's?
hehe. =)
