Sir Niky : Good mods equals a K&N Filter, a cold-air intake or long intake tube, mandrel bent long headers (just get these custom from Brodeth, SMT or Mufflerland), a full 2.25" exhaust and a good muffler.
If ever I'll follow that set up, how much would It cost, and do speedlab have all the things needed? and BTW po, how to get to speedlab? Please please give me a detailed instruction sirs
