Dougs D453s in a 1974 Duster

I have just put a set in my 73 Dart 360. Was not really looking forward to installing them after reading some of the horror stories on here regarding install, but I can say it was a "piece of piss" . If you follow the instructions provided exactly as they say it is all good. I am a builder with a reasonable mechanical understanding & it took me roughly 5 1/2 hours start to finish with headers connected up to modified existing exhaust system. Look on dougs site at the foot notes for installation, it will tell you if they will fit coloum change. Good luck
