As recommended here I had 3" exhaust run to the mufflers. I have 3 chamber flowmasters from there followed by 2 1/2 inch flowmaster mandrel bent tail pipes. The dyno shop thought the 2 1/2 tail pipes would be OK since the cooling of exhaust gases would allow for a scavenging effect.

I notice the sound from the exhaust seems to come more from behind now. Revs were noticably better around 6000 rpm. I've decided to take back to the dyno to document any real gain. I'll let you know.
