Whice pipe is the best one...

[Josue24]

I have to change the exhaust for my 450R but I'm not sure of which one is best to replace it with. I've been told that Lexx and HMF Competition are really good. What would you guys recomend.

Thanks..

[JParisi48]

dasa, curtis sparks, or rossier if u live somewhere sound db is no issue.

[tjsdaname]

rossier or motoworks.

I personally am gonna switch to motoworks from sparks

wtf i have 666 posts/ im creeped out so im just postin again...

[lil_billy_300ex]

I really like my HMF comp series

[patrickj75]

Baldwin makes a good 450r exhaust as well.

[Dirtjunkie85]

I currently Have motorworks SR4 full system, it added more power than my old Yoshy pipe. Consider the Lexx Exhaust for the price, I hear good stuff about them for the price. and they have 4 interchangable tips.

Call Toby at Moto-xperts. His new exhaust is pretty much the best around and he can show you the dyno #'s to prove that. Even when compared with the other "best" exhaust systems that will be mentioned on here.

Thanks everyone for your advise. One of the reasons why I metioned the Lexx was because is pretty economic, but I also want to have good performance so I'd like to start with something good

[leev26]

I've always had real good luck with HMF. I have heard good things about Toby's new exhaust too.

[HurleyBraaap]

what about big gun pipes im also lookin for a new pipe and i saw the big guns and they look really sharp just dont know how they hold up or performance wise?? :confused:

[reptikes]

First off... no pipe is getting you over 5 horsepower when properly tuned. The majority of the big name pipes are giving a 3.5-5 hp gain.

For the 450r i would in with a Curtis Spark or Rossier maybe even a Dasa.
I currently have a new Silver/Black HMF and would trade it in a heart beat for a Sparks or Rossier!

Doesn't sound like much ... BUT I'd say that an exhaust offering roughly a 15% increase in power is pretty good.

:ermm: How do you do your math? 15% increase from a pipe?
That would be the only exhaust sold. At any price! :macho

Do you need a map? What's the average horsepower on a stock 450? Now, the previous comment stated that pipes offer 3.5-5hp increase.

Let's just say a stock 450 has ~32hp
And we'll say we've got the best pipe that supposedly offers a 5hp gain

Here's that amazing math:

5÷32=0.15625

15.625%

Now, I didn't say whether or not a pipe is offering that kind of increase. I was simply analyzing the comment of "3.5-5hp gain".

[hilltop_83]

I am going to get a new exhaust this winter and im leaning toward Dasa, Baldwin, or MXP, if any body has any dyno f those with a stock engine post them up please

[Black Sheep]

There is no such thing as "the best pipe" The best pipe for me may not be what you like in a pipe.

Pipes are a way to fine tune your engines power in a way that works best for you, your engines mods, and your style of riding.

I see people everyday riding with the most expensive and loud pipes and none of them even have the skill to ride past the stock pipes potential.

I didn't read anything in your post about your engine mods, type of riding, or what type of power you are looking for so I'm not even gonna guess what pipe you should get.

Don't rely solely on dyno numbers. While dyno's are a good reference tool I have yet to see a dyne win a race in the dirt

[hilltop_83]

some people are touchy on this site...i didn't say i was gonna get the pipe with the best dyno, i was gonna look at that and then talk to a guy that has been helpin me out gettin my quad set up and go from there

Easy Hot Rod...

I was not referring to your post. I was making a general statement about exhaust and dyno's.


Talk about being touchy :rolleyes:

[HurleyBraaap]

Ok hows big gun pipes bc i really like the look of them they look sharp... Hp isnt a huge deal for me. Do they sound good too?

[sandspanker]

I just bolted on a full motoworks exhaust yesterday. fits is very good. Very good sound my stock exhaust is louder with the baffle out of it. huge increase on power all the way through. with just a HRC cam and HRC needle 185 main.

My bad! I wasn't using 32hp as my base. I stand corrected. :o

[fatboy666]

check ebay. i just bought a fmf factory 4.1 full system with megabomb header for 200 bucks. always good deals on there.

there were a few real cheap big gun systems too.

[armstrong88]

Poor guy's prolly sorry he asked! LOL:eek2:

I have one. Its a decent pipe. It seems to be more of a lowend pipe thou compared to my LTE exhaust.

[450rstroker]

i have a full eddie sanders im lovin it most the pipes r with in a few horses so just go with wat you want i got the eddie sanders cuz i dont see hardly anyone with that pipe

[250ex_dan]

have any of you ever herd of bills pipe or something like that..?

[racing12]

i bought an nMotion pipe off of NeverLiftRacing. My quads ported and polished, stage 3 cam, and 13:1 piston. runs very nice.

[dstracing]

Go to a race and find the fastest guys who get to choose their own pipes- i.e. not running what their sponsor chooses.

[Jonhyboi]

I'm using a HRC combo with a yoshimura slip on. Works good for me.

[2muchquad]

best pipe doesnt exist;)

[Lquad71]

motoworks.
best fitting pipe i could ever imagine
very nice power
the best customer service i have had with any company ive ever dealt with
Motoworks!

[440ex. ehhh!!]

just upgraded to a 450r from a 440ex and i LOVE the full system HMF loudest quad i`ve ever heard. but then again, there are not many i have heard, most people around here ride bikes. :ermm:
