best pipe for 400ex

Are the DMC and duncan Racing double barrel exhaust the same? They sure look like it. The new white bros. R series looks like a polished Pro-circuit pipe too.
Before my 400 I had a 300ex I put on an FMF mega max and jet kit couldn't tell much difference not for the money. Biggest bang for the buck is drop a tooth on your front sprocket. This makes your engine turn more rpm at the same speed, more rpm more power, up to a point. It will slow your top end speed down a little but I never rode 60 mph in the woods or climbing hills

The DMC and Duncan Double Barrel are the same pipes. The difference is the DMC has a stainless steel headpipe and the Duncan has a chrome plated steel headpipe. You gain alot more power with a piston and cam than you do the pipe, but if your going to really modify it and get the most out of the bike, sooner or later you will need a hi flowing pipe.
