Accurate Exhaust Products -Review of Complete System

I just finished installing my complete accurate deluxe dual system on my 67 Barracuda. I had a similar experience. Could use more detailed instructions. I plan on starting my motor for the first time Friday. Very nervous about it!
To expand on my 67 Barracuda dual install, I called TTI first looking for headpipes. TTI told me they could do headpipe for my left manifold casting number but could not provide one to the right manifold casting number. In frustration, I called Accurate and talked to their engineer-Tom. I have him my casting numbers and he said he had headpipes for both and guaranteed they would fit as he was the one who designed the system. Knowing that Ma never made a right side dual system for the 67 273 cars Tom assured me his would fit. It shipped that day and I had it in my hands the next day FedEx. It was the complete deluxe system and I was in about 1K all in delivered. The beauty of the system is how nice the headpipes fit, especially the right side. The whole system fit but it took me a couple days to get it on the car. I recommend them highly and for these rare hard to source exhaust systems you get what you pay for.
My experience and opinion FWIW------DR------:-)
