Hi,all I can say is Wow.This is an exact copy of what I first built in 1983 for my customers.The 2 mufflers into one collector with the Burns center insert I first built in 1991 for a 2.8 short stroke on a 76 Turbo case with 3.6 heads.66 x 95mm.Made 374 H.P.at 9300 & 248 ft.lbs.of torque.Motor had 45mm slides and Motec.I used a mathematical formula where the step to the larger pipe is determined by the CC size of the engine.I will send a photo to JB of my exhaust and maybe he will post it here.I only ever supplied these to customers and never offered them for sale as I wanted to keep an advantage over the competition.Trust me Jb has a great product here.I am retired and had thought giving the info to someone to build these.No need to now.Fred Apgar Apcar Inc.
