2000 S80 T6 exhaust mods
 

hey, im getting ready to have a guy weld me a test pipe for my t6. will a free flowing exhaust (no cats) and a three inch downpipe cause issues with different back pressures and fuel trim controls as far as drivability concerns?

1. Do not go without CATS. Why? Because is some places it is illegal also it will cause problems without them.
2. Your a T6 you have two downpipes so you will need two 3" downpipes.

3" mandrel bent downpipes to a 2.5"-3" mandrel bent catback system with free flowing CAT and muffler such as a BORLA or MAGNAFLOW.
