well i got my dp chip (40,80,120) last night and today i got excited about modding my truck so without much forethought i got out the sawzall and hacked off the exhaust right before the muffler....my ? is anyone who has done this,how did it affect power,mileage,egt's,etc....i took my wife for a ride and she did'nt like it so i might be looking into a 4" exhaust.........btw the turbo sounds awesome now
