Im running a white bros. E-series (s-bend) Slip-on with the prodesign,proflow filter kit, and K&N (dynojet) jet kit.(dj144&dj146 mains) still just a touch rich but runs very smooth great power all the way thru. I'm also running 12t front sprocket. Hope this helps.

 

GYT-R slip on made a big difference on my bike. Some people dont like them I think thats one of the best slip ons out there. It really woke up the raptors bottom end. I dont know if its just the slip on or my other mods ( jet kit-pro flo filter) but its like night and day. I going to try the GYT-R header soon.

3sportsman,

I would have suggested the GYT-R too, but the poster wanted a 'quiet' slip on.

I agree that for a slip on, the GYT-R is one of the best (once jetted properly), but it is way loud.

I have heard alot of them and they are all loud even when you take out the stock baffle. Thats what makes it run better because it gets more exhaust flow. My stock one was so restrictive you cant even see light through it when I took it off. Mine is loud and I try not to **** people off when I ride but I would never go back to the stock pipe.

 

I have an e-series that I run in areas where noise is an issue. the benefit is that it comes with 12 discs (8=stock) and you can add more if you want to liven it up! 16 discs is about the same outlet of the GYTR.

 

i use a white brothers e-series exhaust and i am very impressed that it can be tuned and the power i get

 

I was very interested in the white bros E slip-on.... anyone run the quiet core in there E series, does it still make good power? Thanks for all the comments!

 

the quiet core is good but takes away low end torque wich isn't really a problem for the raptor

 

On the white brothers disk pipes dont it click real loud with the quiet core in? I know it clicked like hell when I had one on the polaris srambler. But that was a polaris.
