[pekeboy0314]

hahah that is a fat cat

[butterflyowns]

thats one sweet looking cat

[feos2203]

Nice sound dude,but what the performance? ;-)

[Vectusr6]

Not sure really. Not many people can get the max performance out of their bike in the first place. I doubt anyone could honestly be able to tell a difference in performance with pipes only.

I do like the sound/looks.

Supposed to be 3-10% improvement.

You can tell after you've riden the bike alot, like some can feel the little upgrades, but some are just not that fine tuned to get it.

Sounds awesome.

but don't forget it also uses up more fuel than before...plus its louder...which is nice!

[Whipalchemy]

lol the cat legged it

[ghostrider51500]

Good way to get the cat out of the garage. He looked scared. I would be to,I have the M4on my bike...Reminds me of a yoshi exhaust.
