Another 09 yz450 exhaust question.

Did a search but did not find an answer. I know the 06yz450 exhaust is a good option for a 09yz450. But I have a friend with a 07 stock exhaust. Will the 07 stock exhaust fit and wake up the 09 yz450?

Yes it will.

The '08 and '09 are the ones with the restrictive cone design muffler.

I'm using a fmf mega bomb to a stock muffler, it picks up the mid to top and it feels more snappy, Im happy with it

I just gput a Dr.d on my 09 like three days ago and it really really opens the bike up!!! check out my little review thread, putting the new sprockets on tomorrow and then im gona do a test

i put on a fmf 4.1 muffler, 165 main, 9oz. flywheel, and a 50t sproket on my 09 yz450f and now the thing is absolutely perfect.....:eek:

The direct answer to your question is yes the '07 exhaust is better that the stock '09 but it doesn't even compare to the performance of the '06 system.
