The for sale section has a WHOLE bunch of used stuff you can get on the cheap. I got my downpipe for 90 shipped. Right now theres a dude with just about everyting you can think of for sale up there.
Beat ya on the first one lol. And I have a 3" DP and a PLOG. Noticed the biggest difference with the DP, the PLOG will just be a big help when I get my tune didnt notice much when I put the PLOG on.
