Got a standard 4 into 1 manifold, but I guess that's not what you're looking for.

Single pipe outside, so presumably the same as you have.

Worth extending your request to the 4-1 race exhaust that has long primaries.  It has a slightly different effect over the 4-2-1 manifold, in that it is mainly of benefit at higher engine speeds, and the 4-2-1 helps in the mid range more. However, its a big improvement over the standard.

I used to have a 4-1 external collector exhaust and found this turned towards the ground where the four pipes exited the body meaning the silencer was low and grounded quite often.

I changed to a 4-2-1 VHPD system which turns straight / parallel to the ground as it exits the side skin meaning the silencer is slightly higher and rarely grounds (usually only when 2 up and hit a bad bump or speed bump too fast)
