I have a 4" mandrel bent magnaflow exhaust for a desiel, i know several people run this size on turbo apps but i would love to see some pics of how you guys do it! Please post up pics if you have a larger 3.5 to 4" exhaust set up!

What are your thoughts?????

 

Mine was a 3" dp to 3-3.5" reducer to 4" pipe with a bullet. Dirt track racer 81 may be able to get a pic for you

 

Thanks im running thunder 550 old 3.5 dp and i am going down to 3" right now. I want to go bigger but not sure of how you guys got around the support for the carrier bearing and stuff. I don't have a local shop to mandrel bend pipe esp that large.

 

PM colton, Charcold-bowtie, i helped him install 4" pipe and 4" magnaflow on his truck...

 

Yeah that support was a tight squeeze lol
