Turbo-Back: Replaces the flattened OEM downpipe with a stepped mandrel-bent down pipe and OEM style flange that bolts to the back half of the system. Use when a few engine modifications are planned.
You may be required by law in certain states to run a muffler, but it’s not required for the truck to run properly. Running a 4” turbo back exhaust without a muffler will often be much louder than with a muffler, but this is merely personal preference. (To verify if a muffler is necessary in your state contact your local DMV.)
