Slip-On or full..................

[Shipdawg]

Hey guys I was just wondering what would work better? a slip on or full exhaust? I know that a full will add more horsepower and torque but will i really be able to notice a seat of the pants difference between the 2? I only ride trails and am lookin for a good exhuast. I already have the hrc kit. thanks.

Depends what else you plan to do to the motor. If you dont really plan on anything else I have read the DR D slip on is tough to beat with a HRC bike. If you plan on changing piston and more get the full pipe.

[Shipdawg]

that is all i plan on doing to it. I want to keep reliabilty and not have to run race gas and spend 5 bucks a gallon for it either. thanks for the input. Also, I'm thinking of installing a trailtech heavy flywheel.

I have the HRC kit on mine, and just ordered the Dr. D yesterday. I should have it by the begining of next week, I'll let you know how it works.

how does the dr. d perform on a bike without the HRC kit.....i dont plan on getting any engine mods in the near future except for maybe the HRC kit....would i need a full pipe...or can i just go with a slip on? Do you notice the diference between a full pipe and a slip on?

[kwatts400]

From what I've read, the Dr. D + the hrc kit is a pretty good combo(Dr. D. adds low to mid, and hrc adds top). I was thinking about the HMF as well, but the db level with the quiet core is a good bit less with the Dr. D. I don't know if a full system is offered for the Dr. D.

I would do a hmf full system with the hrc cam.

yes its silly fast

A slip on is a waste. Spend a little more and get the full system. the headpipe's where all the power is.

I agree.

Yep, full system all the way!

Stock head pipe is a pretty good head pipe from the factory.

The normal rider will not reap any benifits from a full exhaust

hmmmmm. as stated above " I would do a hmf FULL system with the hrc cam" :huh , and now you don't agree that a full system is a good idea?

agreed, i am really happy with my HMF system, it made a night and day difference.

[TRX450rRoostin]

thanks for the advice guys!

[450 Racer R]

All of your power's in the head pipe. The slip on just gets rid of the stock muffler and replaces it with a straight through design. If you're gonna keep the stock head pipe why not just modify your stock muffler? I seen on here a while back during the summer that someone posted up pics of their stock exhaust with the baffling pulled out. Not the spark arrestor. The baffling inside. That's what has it so corked up. It flows through two little holes. Sure a new slipon will give more power, it has less back pressure. But a new head pipe is the answer. And if price is an issue... get a f'n job

[Shawn H]

I have had mine on the dyno and there is not that big a diffrence with a aftermarket head pipe? :eek2:

Im not going to argue with ya:rolleyes:

[TRX450rRoostin]

who is saying anything about price...i was just curious if its worth it....

[Shipdawg]

yeah....exactly. i am just wonderin if i am gonna feela seat of the pants difference between the 2. because if i'm not then theres no sense in spending 150 to 200 more for a head pipe when that money could be used for something else. money is not an object either. besides all the riding i do is trail and maybe some play drag races. so if a the difference be tween the slip on and a headpipe isn't really noticeable then i don't want it. just because a dyno says that i have 2 extra horses with the HP and i can't really tella difference between the 2 then it means jack **** to me. thanks for your input......just lookin for short answers.

[TRX450rRoostin]

so is the dr. d good for a stock bike....without the hrc kit....

[kwatts400]

It won the dirtwheels pipe shootout for the yfz 450, over the fmf, big gun, hmf, and others. I'm guessing it will be pretty good for the r.

[450 Racer R]

anything that has a straight flow through design will be good.

[ckasper18]

Go with the full pipe but make sure you check where you ride about the db limits my buddy just got nabbed $175.00 fine for no spark arrestor and too loud of a pipe riding on a frozen lake no spark arrestor what does the dnr think he is going to do melt the ice.

[TRXRacer1]

Oh god, are you guys serious? A full system is a waste unless your gonna build it for high RPMs and are going big bore. It's amazing what buddies systems have done, lol. I know pipe design is tuff but it wouldn't hurt if we learned a little about it people.

I meant to type slip-on. sorry.

[devil6]

From what i've read, the stock pipe with the hrc cap will flow as good as any slip on u can get. And the pipe isnt the limiting factor, the cam is. So unless your gonna switch cams, don't get a full sys. And that the HRC cam is one of the most top end oriented cams available,so it wouldnt be good for trail riding anyways, look at hotcams stage 1 or 2.

[bobbo97f150]

I would spend the extra $150-200 on something else. That's what I did. I've owned bikes with both full systems and slip-ons and there is not that big of a difference. Especially for the riding that you want to do.
