I have the full ti graves system on my 2001. I love it. The fit and finish is awesome. I got gains of almost 12rwhp with just the system installed and NO jetting. Torque is at 77.9 at the wheel.
If you want a full system from Graves drop me an email and I'll get you a awesome deal on it. I'm a Graves dealer.
Do a search because I took a pic of my dyno sheet and posted it. It's a pic...but you can see the gains.
see ya,
dave
