cool Thanks for the info..... anyone installed the TRD upper and lower sway bars by them selfs or do I need a machanic do install them?

Hey, running the xD without a muffler would cause issues. Air/fuel ratio would be off cause you wouldnt have any back pressure in the system. Long story short you'll lose power...

thanks have added it
