Custom headers and exhaust
« on: April 22, 2019, 04:52:44 pm »
If you send your engine to Hurricane Motorsports, do they make headers for your engine? Also, what size diameter is the side pipe 4 in?

The reason why I asked... Is my engine builder has a set of requirements for the engine for the headers.

They are... do the headers as a step, 2”to 2 1/8, with each segment 15.75 to 17.25” if you have enough room. If you use a merge collector you want the throat to be 3.25-3.5 with a 4” outlet. Standard collector should be 4”.  Best tuned lengths (end of primary to end of sidepipe) would be 34.5, 68.5 or 137.5” long.
