Making 03 raptor 660 Faster
 

How could i make my 660 faster im get a monster dual exaust system or what exaust system gives me the most hp? So how else can i make my 660 faster? Like i want to go faster than 700s.

Exhaust, intake, jetting. Those will get you a very significant power increase.

LOL Wont take much to beat a stock 700 but for what you are looking for I suggest talking to the guys at Modded Raptor - For the rider that can't leave anything STOCK! to get you going in the right direction!

If it was mine, Id put on a HMF competition series pipe, (slip-on is good, but full system will give you twice the power increase over a slip-on) K&N air filter, and adjust the jetting. If that is still not fast enough for you, maybe a gearing change?

So the HMF full system has more hp then the monster duals?

No the HMF does NOT have more HP but the duals weigh more so its kinda off setting!

What exaust do you suggest?

sorry, when I recommended the HMF, I forgot you said that you are getting duals.. if you're going for lightweight, the HMF would have a definite advantage, (like Dodge said) but Im sure the duals would have more potential than a HMF system. i guess it just depends on what you ride.. if its roads, than I think the duals would be better, but if its mx or dunes or somethin similar, maybe look into the HMF

I like simplicity and dont want or need large sound one system that is getting allot of attention these days is Motoworks and I would highly recommend them.Motoworks

barker dual exhaust ;) mod for mod a 700 is going to be super hard to beat though, they just respond to mods so well. and imo if you start going in the engine u need to get a new crank asap cuz the stock ones of the 660 just suck ass.
