my cat is empty so i need to hang 2 new cats on the car, it had shorty headers that step down to slip over the stock cat tubes, then an after market s/s cat back. i an having my friend that works at GHL make me a new cat section from another cat section , but i was wondering what are the sizes of the stock cat tubing and what is the common size of the cat back systems. although i am stuck with the step down at the headers i would like to try to go with a bigger size tubing to match the cat back. sizes any body?
