I have a FMF Power Bomb Header and Titanium 4 silencer with the 2" end cap. I have a 12:1 686 what is your opinion on the best exhaust for the set-up? Lets hear from the big HP boys.[img]i/expressions/face-icon-small-wink.gif[/img]

 

Alba!!!

They are very loud...but very powerful.

 

I got a graydon exhaust for my 250EX (nothing compared to a raptor) and it actually helped out that little bike quite a lot, might wanna try one. I heard CT makes a good exhaust too

 

IMO it would be the MBRP drag pipe[img]i/expressions/face-icon-small-shocked.gif[/img], but I have this feeling thats not what your after.[img]i/expressions/face-icon-small-wink.gif[/img]

Honestly I think there are many good pipes out there, it just my FMF is not one of them.

If I was going to buy a full pipe system tomorrow it would be a MBRP full bore. Not specifically for the most power out put, but the whole package, polished stainless, fully welded construction (I really like that part), and no packing.

You could chose any one of these:Sparks, MBRP, Yoshi, CT That would be the top four IMO.

 

Thanks guys, I'm just trying to unlock any hidden HP without getting back into the motor.

From what I have gathered from reviews and others opinions... Sparks and LRD are great for full on no care, no consequence performance. Most reviews out there that take more than performance into consideration (such as forestry approved spark arrestor and lower decibal level) Seem to always put CT, Pro Circuit T-4 and White Bros (e-series and R4) at the top. Alba exhaust is usually the loudest in the reviews so I wouldn't even consider a pipe that tests at 102 decibals (according to Dirt Wheels mag).

My YFZ is still running stock exhaust, but my wife has a warrior with a White Bros E-series on it. Its louder than some (my friend has a CT on his 400 EX and its very quiet but still has a great quality of sound) but it sounds nice... The e-series looks cool and made the warrior a bit more snappy although it didn't perform miracles.

If I could buy whatever I wanted I'd go with the Pro-circuit Ti-4 at the moment.

Best bang for the buck is most likely CT... they aren't an arm and a leg and almost always rate at or near the top in performance.

 

I like the sparks it is kind of loud but sounds very clean. It is also HPC coated so it won't ever change colors like the stainless pipes do. I had an Alien for a while when I switched had a noticable difference but once again no miracles
