66 Galaxie z code 390 4v, stock power robbing manifolds, slight hydraulic cam.

Exhaust is stock configuration except for being 2 1/4" rather than stock 2 "
Mufflers are Flowmasters. Tubing is aluminized.

What is interesting is the H pipe. My good friend Gary of 33 years has been in the exhaust business for 29 years. He is an excellent custom exhaust man and a real perfectionist when it comes to this kind of thing. When we built the system, and the job was done, I told him I wanted to hear it before the H pipe went in. (I was in the exhaust business for 15 years) We let the car down and started it, and at that point I made the determination that there would be no balance tube installed. The sound was EXACTLY what I wanted. Gary insisted that it get the H pipe. So we compromised. It got the H pipe, but it is non-functional. A dummy if you will.
