Hi guys,

Just need some advice on what type of header is suitable for the .21 nitro engine I have.

The engine has a forward facing exhaust with a 16.5 mm outside (0.64 in) diameter

and the pipe is 19.00 mm outside (0.74) diameter.

Needs to be 180 degrees with level curve.

Center to center (ie. curve diameter of pipe) is not too important.

Looking on Ebay for suitable car/buggy headers, but it is hard to get the right one that will suit my exhaust diameter.

Any ideas would be great.
