It doesn't make it hard to ride at all, but it is a good pipe. The carbon fiber sleeve is just bling and can crack easily, especially if you don't repack it often (carbon fiber does not do well with heat). You can get the normal factory 4.1 with a stainless midpipe for a lot less money and get the exact same performance.

The best exhaust imo.
Great sound,Great looks,Lightest exhaust,Great power increase.
unfortanatly the carbon muffler gives a sweet look its also pretty sensitive.
Need more repacking then usual,when you crash its possible game over.

My '08 450 has pretty much the same pipe (accept it's Ti) and runs well. Good power, not uncontrollable.

i was just going to asy what KJ sid but he beat me to it, carbon fiber holds heat in and doesnt disapate it like metal does thus causing you to burn through your packing fast and when all you packing is burnt out you can gets super hot and CRACKS, $900 down the drain! go with titanium or SS. i like the SS myself and i have a SS Dr. D but titanium looks trick too just more expensive
