I picked up a used, take-off 4" exhaust (previous owner upgraded to 5") for my '98 Dodge Cummins. It's complete, minus the down pipe from the turbo. Anyone know where to get a 4" down pipe for a 2nd Gen CTD that doesn't cost a ton of money?
I'm going to ditch the muffler that came with the 4" exhaust & run a 4" Aero Turbine XL, the 4040XL. It's the Aero Exhaust diesel motor version. They have a built in resonator that helps eliminate the 'drone' that you get with other exhausts. My '99 was straight piped & it resonated BAD at specific RPM's.
