    back pressure... I worked in the Fuel& Exhaust lab at Chrysler for 35 years and did tons
    of testing... if you notice now days the muffs on most new cars is back as far as possible
    to gain a few things... more HP due to the lesser back pressure and its easier to control
    the sound
    Great insight, thanks.

        That is being an equal opportunity offender.
        Why think when you can be doing something fruitful?

                    I noticed a difference when I ran the 3" exhaust over the 4-Link and all the way out the back; much quieter to the ear. It limited my access to the coil overs though and I mounted my trans cooler back there so exhaust is back out the side in front of the rear tires. I think I'm gonna have to send my uncle a 'Basics of sign language' book so we can communicate during DW this year.

                            I think getting the pipes out to the bumper makes a huge difference. On the other hand... there is this approach...
