[YENKO DEUCE REGISTRY]

I forget which muffler is on my car, but the sound is perfect! There is no resonance in your ears when you are cruising or idling - but enough sound to let folks know that its running. However, when you jump on it - the sound really wakes up. The video on the Pypes site of my car is ok, but you need to listen to one in real life before making your decision. They angle cut the tailpipes for me and installed them exactly as factory - and only crossflow muff's for Novas in '70 (and resonators).
