I’ve had several different exhaust configurations since I’ve owned Josie. All of them were acceptable except when I was running glass packs with straight thru’s. That configuration was so loud it was embarrassing. I picked up a pair of Flowmaster 10’s from a guy in Livermore. He had it running on his SRT Magnum and removed them for a different type of exhaust.
I’ll have them installed next weekend when the storm blows over. I don’t want to take Josie out in the rain since I don’t have my new weather seals installed (except the trunk, that’s done).
One thing that trips me out with the exhaust from the older cars in the 1960’s is the diameter of the pipes used. Mines are about 1.75″ and the newer exhaust looks to be 2.5″, definitely larger diameter than what I have now. I guess back in the day that was a normal setup.
