I just installed an Accurate system on my dart sport from manifolds to the rear bumper. I spoke with Tom before the Chrysler Nationals at Carlisle this year as his listings went up to 1974. I have a 1975 360. He couldn't locate my manifold numbers in his books so he settled on a 318 head pipe setup, which went right on with the exception of the R/S head pipe. the bell that goes over the manifold wasn't quite opened enough so a trip to the local pipe shop to have it opened took care of that. I got the entire kit, with all the clamps, hangers ect. I got it in 2/14. Good quality pieces and fit. To bad the system stayed boxed up in my trailer since July, but has been a hectic summer for me. I wasn't going for performance but I don't believe it would hamper it much, I like the sound and stock appearing. Good luck with whatever you decide. Myself I'm pleased, my two cents.
