    I am gathering parts for the SAS swap on my 92 FS Blazer. I am buying a GM front D44(because everyone in Cali thinks their Ford axles are made of precious metals.) My questions are about the exhaust, everything else is straight forward. The great corrupt state of California and the smog nazis that run it require me to have biannual emissions testing. I have to have a catalytic converter on this thing. Will I still be able to run the exhaust on the passenger side and use a Cat with the pass side drop transfer case?
    Anyone have pics to share?
    Thanks

    No. You will not have enough room to fit the exhaust on the passenger side still with a passenger drop t/c there.. lol at the drivers side currently. That's how much room you will have after a pass drop t/c is there...

    I've got some Dough Thorley headers and Y pipe that were on the stock 454 on my SAS with passenger side drop NP205 and Dana 60. the exhaust is running down the passenger side just fine. The only issue I have is the Y pipe has hit the passenger side shackle.

    The exhaust will be tight. Wrap the pipe in header wrap to keep the heat down around the shackles if you need to.
    I’m working on a the sas on my 93 c1500 and I found the pacesetter shorty headers keep the flange closer to the block than most others.
