Topic: Exhaust for a 22RTE

[AZ 4X4]

I have a 1986 Pickup with a newly rebuild 22RTE and rebuilt turbo. The vehicle does not need to run through emissions so I am not going to use a Cat. What size pipe should I use and where should it start. I have the factory down pipe as of right now. Thank you for your help.

My 22r-te, when i build it someday, will be getting 2.5" all the way back from the turbo. Not sure it is necessary but hey, Easy breathing
