Fatboy 4

[R3Concepts]

Anyone running a Fatboy 4 pipe on there 450R? I would like to know what it looks like and how it compares to say a Sparks pipe. A customer is interested in it and I have no idea what it looks like or power it puts out.

I have the Duncan Fat-boy 4 exhaust. Sorry I don`t have any pic`s but as for the quality.fit and performance I give it AAAA++++. If you have any issues with jeting just give them a call more than willing to help.It does come close to the radiator hose, what I did, I used exhaust wrap like they do with cars,it supposed to burn the gasses better also protects your hoses etc.The header pipe is SS and the canister/muffler is Alum. The sound is Music to the ears,not real load but nice...This pipe will last, Good luck, hope this helped some....:cool:

Thanks Maine, thats what I was looking for. I had meant i had not seen one in person. I saw duncanracing.com and along with every other site they are out to prove their pipe is the best and we all know the holeshot says who has the best pipe. Or best rider? Or more motor? Ah hell its one of those.

Just an F.Y.I. Don't use header wrap or your pipe will not last even being made of stainless. The wrap will cause the pipe to chrystalize. Wrap the hose instead. Built many headers and have seen many fail due to wrap.

I also Have the Dunan pipe on my R and it really woke up the bike I love it.

How loud is it compared to just using the HRC endcap?
