• Hello,
  
  I'm wondering what was the stock exhaust size for a 1996 AAZ motor? I've got 2.25 inch exhaust in my caddy, wondering if I need to go bigger to fit the AAZ?
  
  Thanks,
  Bill

• 2.25 is plenty. This isn't a high-revving motor.

• I did a complete s/s in 2'5... ( Techtonics tuning )
  
  Gas was like 1-7/8 tiny...
