I've got a D&D on my f4. If its loud your lookin for, then thats what you want. It'll rattle your teeth from about 7k rpms on up.[&:] It's got a real deep idle that I really like, especially when my bike and the pipe get good and warm. It came with my bike so I cant compare it to anything else, but I can say that if I were to spend the money for aftermarket exhaust, I would have gotten something a little quiter, cuz it really screams. If you put on a lot of miles, I would say get something else thats not so loud!!

 

l run Bridgestone BT021 on the rear and BT020 on the front, due to comuting everyday. Got 4000 miles from my old 020 rear so hoping to get more from the 021.
As for my can, l had a custom made carbon fibre oval can made 30cm long, looks sweet and sounds just right.

 

I got the metlzer m-1 sport techs and been up to deals gap a few times and they felt very good. Gave me lots of confidence. And I have a two brothers carbon. I just chopped it in half and the sound is o so sweet.

 

Damn all of you guys have sick parts on your bike.

I just have a Hindle exhaust, which I'm going to take off 4 inches.
Make a shorty out of it.
As for rubbers all I have are Bridgestone.

 

i run pirelli diablo on the front, and pirelli diablo strata on the back. I also have a yosh rs3, and i love it.

 

For tires i use Bridgestone battlax BT 014 (F/R). As for the exhaust, Laser Hotcam

 

Haha, its pretty tough to ask whats the best... pretty subjective. Seems like everyone loves the tire that they have now... lol. I have dunlops, they're not wearing like I hoped they would, but for the price I paid for them I'm happy. They seem to handle pretty good when they're warm too. As for exhaust.. already said earlier bout my D&D
