Don't forget that dyno charts don't take into consideration the 20 pounds you're saving by switching from the god awful heavy stock cast iron exhaust. Handling VASTLY improves.

I dynoed my 2003 ex 250 with a muzzy K&N pods and 110 jets with a Dynojet kit . It was just under 30 hp with 13 ft lb of torque . It ran great.

Yep, 29hp for our racebike.

cool thanks for the feedback, i still dont know where to go with my exhaust ive seen the slip ons make as much power but i want a 2 in 1

Get the Muzzy, it is the best pipe out there for the old gens.

just got offered a new..old yoshi 2 in 1 400 bones

The older MUZZY w/ the more horizontal muffler is better, so get it. They make the new ones more angled up tolook modern (i guess). But they drag the ground around corners.

this one?

yeah hadnt seen it here. what cha think is this a reproduction?

dunno... I was hoping R&T would lend his expertise on this. :)

Oops I meant the older Muzzy NOT the Yosh.

Stick w/ the Muzzy (even the new one) over the Yosh. It doesn't cost much more than that and is a MUCH better pipe. Stainless Steel pipes too, not painted.

What about the sexy area p?! Lol

still waiting for the area p, i was bored and wondered what the dyno charts look like on other options

would pulling my baffles help as opposed to buying the aftermarket exhaust, weight loss isnt a big concern for me

:rolleyes:

15 pound weight loss on a 300-odd pound bike SHOULD be a concern for you, that is assuming that you are replacing your exhaust pipe for performance reasons? Or are you a squid just looking for something noisy? It's not all about horsepower when it comes to anything with a motor in it. It is about the POWER to WEIGHT RATIO. You honestly won't see more than a couple HP (if that) from a new exhaust system, BUT coupling that couple horsepower with a dramatic weight reduction is ultimately where the performance is going to come from, particularly on an engine as underpowered (compared to other bikes) as a 250.

well yeah i am a squid( regardless of the majority of the forum members opinions on this issue) and im probably bigger (weight) than the average 250 rider. my bike is jetted and i allready have say 2/3 the performance than with a spendy pipe and my question was to someone who has experience with this issue. save your b.s. for one who cares what you think. i was hoping to hear from one of the fellas who gets their hands dirty. i think i can poop 15 lbs out in the morning if i need to.

again anyone out there pull their baffles after jetting?

oh and i believe the bikes wet weight to be more like 360 or so and with my say 220 whats 15 lbs?

I dynoed my 2003 ex 250 with a muzzy K&N pods and 110 jets with a Dynojet kit . It was just under 30 hp with 13 ft lb of torque . It ran great.

even without the muzzy the 110 have produced the best a$$ dyno results for me,
what are yall doing with your needles, and if anything with the pilot jet and floats?

Don't forget that dyno charts don't take into consideration the 20 pounds you're saving by switching from the god awful heavy stock cast iron exhaust. Handling VASTLY improves.

you sound like your paid by someone selling a product that saves a amazing 18lbs blah blah blah, the way half yall talk around here makes me laugh

FYI 18 pounds is about 5% of the wet weight. +3 horsepower is somewhere between +10 and +15 percent which is a very large amount.

dude wtf has this got to do with what i was inquiring

some people may run around at 150lb body weight with their -18lb exhaust weight and one gal of gas in the tank and its relevant to my question how

if i could save 18lbs unspung weight speak up . i allready run a mt 75 so what % did i save there einstein

is it really cast iron ? please dude post something about changing your oil and ignore me

all you people with squid comments or whatever you baptists wish to preach go on ask alex to open up a saftey forum or a tampax forum
and leave the people with geniuine performance related questions alone

Whatever... Good luck

The exhaust is worth the $$$. In weight and HP. It makes a HUGE improvement even if the numbers seem low.

I would love a 2 in 1, but i'm really curious about seeing what the stock system can put out/ I know your bike has alot of machine work done on it iirc

No machine work at all. The stock exhaust chokes even this small motor. Not worth messing w/ IMHO. The Muzzy will tuned to give a very good pull all thru the revs. The stocker will not do this. It needs to be turned into a boat anchor, it would work better.

sorry i was reading someones mod list and thought it was you, Now that my intake has been opened up i agree that improvements can be made. If I can free up the stock exhaust and gain a decent % of the gains possible with the muzzy id be happy. Found a neat article might try something along these lines

I'm thinking maybe use a different material than the stock stuff , gonna have to think a bit:eek:

Lots of fail in this here thread. That is what we call an ALL SHOW NO GO mod. It's like you're waiting for someone to tell you what you want to hear, but when people like myself and Greg_E, and R&T tell you the importance of HP to weight ratio, and the awfulness of the stock exhaust system, you start cussing us out because it's not what you want to hear.

Pulling out the baffles will give you maybe 5% of the results of a full muzzy system. You will hardly shave any weight off, and you'll have a touch less back flow. I say go for it. Then when that doesn't work, come back to this thread and re-read it when you want to get serious about an exhaust upgrade instead of Tim Allening your way through an exhaust modification.

Well put and not as rude as I kept deleting from my posts.

I could not figure out how to explain what you just said to him w/o coming off as a dick. :D

i am serious about upgrading my exhaust..thanks for coming back to let me know what a idiot i am.

btw tool time rocks

oh i havnt seen a jetted bike with pods with a stock exhaust on a dyno, but my ass dyno tells me that the muzzy or areap or whatever isnt gonna do much except lighten my wallet but as you have all pointed out the handling will vastly improve

come off as a dick if you prefer, i've appreciated your input

Nate, have you bothered to look at the dynos for the area p exhaust? Your ass dyno is pretty inaccurate if you haven't

even without the muzzy the 110 have produced the best a$$ dyno results for me,
what are yall doing with your needles, and if anything with the pilot jet and floats?

. I ran my 2003 on the dyno with the needle from the dynojet kit in the center slot. Like I said DJ #110 main jets. It was very lean with the K&N pod filters. It had a BAD flat spot when you would open the throttle. I think I got to #38 pilot jets did nothing with the floats.

I have watched a lot of 250cc runs . people with first gen 250s running for land speed records at Maxtons Monster mile . and Drag racing . From what I have seen . Just pulling the muffler goes faster than a Muzzy. But I don't know what they have done to there bikes. But bang for the buck You cant beat something for nothing that makes horsepower and noise. And the flames are cool .

ok thanks racer x, we need more like you around here... from what i understand it's their intake that really has the restriction and yes ive looked at the area p dyno charts. My ass dyno works ok lets see a comparison between a jetted, podded bike with stock exhaust. My point is the exhaust is a waste of money imho

So this un godly heavy stock exhaust is cast iron??? and with less back pressure i will gain 5%?? thanks bro

I'm sorry if I missed something, whats the zipcode the at maxton ill come out?

Gosh I don't know the zip code of the airport that we race on . The hotels are five minutes away and there zip is 28352 . The next meet is this coming weekend 19-20th.And super street bike fastest street bike shoot out. With speeds approaching 250 mph.

If you want to do any serious modifications the exhaust is the best place to start. But alone it is not much good. But as a complete package of intake exhaust head porting the stock exhaust is far to restrictive . and heavy. For riding and resale a muzzy wont help. As a matter of face . I still have the muzzy from my 2003 . I put the stock pipes back on and sold it for the same price. The customer did not like the noise.

well i think the intake is the best way to start $ wise and since it needs done anyways with those 400-500 buck pipes...

anyways my intakes done how much for the pipe?:D

What did you do to your intake to improve its flow?

FYI - you can't do anything to it in most Orgs. as far as the intake goes.

umm removing the airbox....

LOL, OK!!! Serious mod there. hehehe

i do thinks it's a serious mod when compared to stock, if you don't well laugh some more

and i think what i've been talking about lately on the thread i started is getting similar performance with out spending as much money which you must have so, laugh some more

I am going to use the one I have for another project .But I think I paid about 400 for it.

Wow, why the attitude? I thought you were talking about real intake mods. Sorry for the confusion.

Yea, going to pods if jetted right work great and is cheap. Some Orgs. don't let you do that either though.

My bikes don't have alot of $$$ in them so i don't get what your saying.

ok just returning what i thought was a shot, so umm you do have a super looking bike

i do consider it a real mod, and the bike thinks so too

also it's a mod that can be done cheaply and doesn't require machine work

I guess the confusion is that I only race motorcycles, I don't ride them on the street too often. So I tend to only think about racing and winning.

As a racebike, which I thought this section was discussing, you should get the MUZZY on the older gen.

M4 on the new gen, but the Arie P seems to work great too. I just have no 1st hand experience w/ the AP.

Remember, I'm talking about racebikes and winning roadraces, which I have some experience with.

cool, no this thread was started out of curiosity about the 2 in 1 pipes potential.

now i'm just a poor boy who's curious period

This kids young but he's not dumb..people if you want to flame me here, go ahead but anyone who reponds about what a fool i am i.e. I got a muzzy blah blah area p blah blah if you had your bike jetted when it was done you got no clue what just improving the intake side of this engine does . And if you ride a 250 you probably don't have 1/6 msrp to throw at a hp or two...jets= cheap, pods= cheap($60 or less if you want the foam bull$%@#)..the exhaust= 400-to what 600? Gimmie a break

BYE the way i've seen a dyno run with the the slip on's making comparable power to muzzy or area p..I,m gonna look for it again

LOL, OK!!! Serious mod there. hehehe
if it was'nt a "mod" why am i having to run such a big main? It became lean for a reason after taking that stock box off perhaps..but for some strange reason it's still flowing well.

The reason i ask baffle questions is i still have the 112 jets and it hit pretty good on top with them..not as well as the 110 jet with my crappy cast iron...LOL

and i got 115"s maybe if i just took the exhaust off completly i could use them
