Alright so I recently bought a TD04 turbo off a wrx that I will be adding to my 01 legacy. I was snooping around on nasioc abut catless downpipes and some other minor things about the project. What is your input on downpipes? I was going to try to cut on cost and possibly go with an ebay special, OR go with a higher end dp ie: Invidia, Cobb, Grimm Speed, etc. Secondly, should I buy a bell mouth or divorced, I want as much turbo whistle as possible out of it. *I plan on running headers w/ catless up pipe to the catless dp then to a 3" straight pipe back. Give me some feedback on your setups!
Here is the post I was reading regarding dp's: http://forums.nasioc.com/forums/showthread.php?t=445812
