dual exhaust slant 6

My wifes 63 Valaint has 2 1/4 out of the manifold to a splitter, then those 2 pipes go to 2 flowmasters.....then 2 1/4 all the way out, on both sides....w/ chrome tips. It sounds like a smallblock ideling....man, its sweet!! Overkill??? Maybe, but I LOVE it.Drove it to Vegas in 09, and raced it.....the drone for 18 hours straight would have been a downer , but I am a car guy, loved it.
