I've heard some say the straight pipe is fine for power, though the larger diameter pipes are better for temperature... Then again I've had some say go with the four inch and not the five... I'm not into super quiet exhaust systems.. I currently run the straight pipe and wouldn't care if it were even louder.. Has anyone seen actual dyno results between aftermarket systems and factory systems with a straight pipe?? Thoughts on a four inch or five inch system?? I had thought the more free flow on a turbocharged motor the better... That is until I talked to the diesel performance shop that's upgrading my juice told me different.. Help would be very much appreciated...
