[BIG_BORE_660]

I am looking to buy an aftermarket exhaust for my 03 Raptor. I was considering the HMF slip-on. I would like to pay between 200-300 dollars. I want the pipe to be really loud!!! Any help would be great. :thumbsup:

Re: 660 Exhaust

If your looking into just slip ons the t-4 by pro circuit is a great pipe for 250-275 new and it is loud as hell. The white brothers pipe is the same way, but i think it costs a little more. I have the dr D slip on on my rapter..i found it on ebay for 250. I love it, it gave me power all around and it sounds great..it has that great tone but it's not so loud that it bothers other riders around you. If your looking for a full system i heard the yorishima one is a great one, and the tle duals sound amazing but a little exspensive.

Thanks I'll check on them

I have a Dr D and it sounds great but my buddy bought a Big gun and that is one sick looking exhaust and it sounds great too.

mine is a yoshi slip-on, its really loud and pretty good performer for the price. i need less than 5 mins to get neighbors complaining about my bike beuing so loud :grin_nod:

I just added a yoshi rs3 slip on and this thing is loud. It also came with a silencer which of course I took out and replaced with a $10 spark arrester screen direct from yoshi. After that it was even louder. My friend has a gytr slip on and that thing is pretty loud but there's people on here that say the gytr is crap. Good luck. :thumbsup:

im using the fmf powercore 4, its not as loud as the white bros pipe...until you get on it, then your neighbors wil be glad you are leaving

I have the Yosh RS3 full system. Loud as hell and looks awesome.

why is the gytr crap? I bought a gytr carbon fiber slip-on for 20 bucks, so i guess even if it is crap-it has to be better than the stock muffler right?

They work well, they just don't hold up long.

 

[Spaz_22]

They sound weird, and they don't perform as well as equally priced slip ons. Also, almost anything is better then stock. after markets are lighter, louder, free up your exhaust and add more power

 

[twistedwedge]

If it was recently re-packed should I expect it to last for a while? Wish I had more of a budget, I would have bought something else..

Just keep an eye on it, and don't tighten the clamps down too much just enough so that a backfire won't shoot the pipe off the bike.

Alright, Not to invade on his question but what exhaust (single exhaust) gives the most HP. My buddy recently got a Trinity and he does nothing but swear its the best exhaust hands down for delivering the most hp gains. I ordered a yosh but received the wrong one and sent it back.. Now Im really considering looking into somthing else. Im looking for any info to help me shut my buddy up or at least believe him. Lol Ive heard Sparks is really good and also the Yosh. Anyone know?

ct racing makes the most dyno proven horsepower as far as singles go

I have nothing but good things to say about the CT racing pipe. It has the disc's not the open end cap. Its loud when you want it to be(up to 103 db) easy to reduce the volume by taking out discs..with a little loss of hp. Just had a hell of a time jetting it..but I think thats normal with a raptor 660. I think its about 1-2 hp more than a yoshi or sparks (so I've read and heard) but heavier.
