250-500cc Pro Circut pipe

I received a second black factory pipe with my 300 when i bought her new. the shop mentioned that it was a free flowing unrestricted race pipe. question is, can i expect any benifits by fitting a pro circut platinum pipe and silencer? note that i also have the high compression race head fitted with pwk38 carb.

cheers.

I have an 09 with that exact setup. 1st mod was the carb. 2nd was the PC pipe and silencer. Awesome mod. Livened up the bikes bottom and mid even more. Very noticeable over stock for me. 3rd was the race head.
I play with the gearing 13-50 for Summer singletrack 13-48 (stock) for winter desert. It is awesome. WIth the singletrack gearing, it really gets out of its own way in a hurry!
I would say run the stock pipe until you mash it...and you will. THEN replace it with the PC system.

i only have desert here with lots of salt bush we tend to break ourselves before the bikes in th big dunes
