diamond eye?
If you're talking the system from Rip I have a close copy. I run a 4" system with the same Allied straight thru muffler. I mostly like the sound out the tail pipe except for a couple of items:
I have a nasty drone around 2,100 rpm.
I have governor springs and the exhaust has a "hiss" when I get on the throttle and engine rpm climbs to 2,500-3,000 range.
I purchased another Allied muffler to (hopefully) cut the drone.
Don't forget to add the 5" SS tip.
