Quince exhaust pipe

[Mallett]

Dose any one know where to find them, or do I start cutting and welding pipes on? Trying to go loud

The bottom pic is the Quincy adaptor with the rare plate originally designed with vacuum cleaner pipes. The first 2 look like Quincy the evolution being 2 pipes then 2 in to one. They work best with a filler block.

Thanks for that, what’s a filler block, a shim to attach it to the motor? I’ve read all about them on the Quince pages. I have also seen a couple on kg Mercury’s in private collection’s.

A filler block is a machined chunk of (usually) cast aluminum made to fit in the exhaust cavity between the engine block and the base plate of the pipes. It provides a distinct passage from each port to each pipe. They are machined to exactly match the port and block contour on one side and the pipe and base plate on the other side. The filler block gets bedded in place with some high-temp goo but not as permanent as JB weld for instance. Pipes without the filler is just a silly exercise. Wanna make noise ? Find a piece known as a Quincy dump which doesn’t need a filler block, it just replaces the stock exhaust cover. Early on, Mercury engineers found some free horsepower by just dumping the exhaust to the atmosphere.

"Fox News" isn't.
