Can anyone recomend a good exhaust system for the yfz450

 

Well, I am running the procircuit titanium-4 full exhaust. Its awesome, and gave me a lot of power! It was like night and day!
I have heard good things about the sparks exhaust too, so maybe check into those. I have also heard that the gytr's will give you more power, but not as much as other pipes, same goes with fmf.
Up to you, there are a lot of exhausts out there. I just liked the looks, and the weight of the ti-4, and the promise that it was going to be an awesome power upgrade!
I think one of the best exhaust out right now (not usre if its available for he yfz) is the WB, carbon fiber race E-2. That will run you like $995 though.

 

Read this pipe shoot out and think twice about everything else you hear from the forums before
making your decision. Remember the YFZ450 engine is just about identical the the YZ450F after doing
the cam mod.


YZ450F pipe shoot out

 

You can't go wrong with a Curtis sparks pipe. Trinity is also ok but they have power pros make there's

 

note how well the gytr system stacks up to the others...
thats what im running with no complaints...
there all going to be fairly close...do the cam mod and add a k & n and youll be rockin'

 

I had the GYT-R and changed to the Sparks. I like the Sparks alot better. It has a little more bottom end and pulls harder all the way up.

 

Thanks for the input , I gotta go with sparks...
