me to but i just dont like the way it looks, my brother dosnt either( he is the one getting the trx450r)

[jb500ex]

if you plan on doing gncc's make sure it will meet next years db level

[Sportrax10]

Curtis Sparks...

Not sure if im getting it right away though...

[norrisboat]

sparks or dmc for me.

[FASTeR]

Check out bob murray at Thunder Alley Exhaust (http://) he built one for my yfz, using a real reverse cone megaphone pipe, its nowhere near as loud as the 120db tc, more like 106-107 depending on the meter, which is perfectly legal for gncc's. And wont cause trouble at the gnc's, he can make it as quiet as you want tho. 360 for a bare steel system +70.00 for ceramic, this pipe is head and shoulders above my sparks full system for the yfz, which Is gone now!

sparks full exhaust is on order

[lukester720]

i think i might be getting the ct full system. I made some phone calls to pretty much all the pipe manufacturers in dirt wheels and got info from them all. About 4 or 5 of them will not have hp numbers till the end of this week but so far the ct is in the lead with 8 hp max increase with hmf a very close second. Duncan told me that they don't dyno there pipes that just do seat of the pants. sparks told me 3.5 hp full system. The only obvious lie i got is when i called trinity and the said they would bring the 450r to 51 hp max i about crapped my pants laughing so i called them back later and the guy i spoke to said they haven't hade ne in the shop yet but will have one monday and have numbers by friday. yoshi and most of the others said they would have #'s by the end of the week. If you look through the old dirt wheels mags ct has been at the top for dynoed hp #'s in the last 3 exhaust shootouts i've seen including the z400, raptor, and the 400ex although there pipes have been amoung the heaviest.

i hope this helps.

[r450rr]

i think i might go with fmf or pro circuit.. just depends on which one i can get cheaper

[jb500ex]

the ct's are usually the loudest also

Actually they were some of the quitest in the shootouts because they used the spark arrested pipes the ct's were in the mid 90's if I remember right. The shootouts are posted towards the bottom of the dirtwheels website.

[sjw1176]

where are you guys ordering the ct pipes from

[lukester720]

www.ctracing.com they also have the phone number on there. The guy I talked to was pretty cool. Hmf sounded teal good too!

[jdt]

LRD will be my choice, hands down.

[jb500ex]

that must be as of this year because they were always the highest

[lukester720]

I believe your right jb. The 3 shootouts I was talking about happened in the past year. Check out the shootouts on the dirtwheels website that's where I'm getting my info on that subject.

[Andy479]

I had a full ct exhaust on my z400 and it was great for wide open riding but I lost a TON of bottom end.....they are mainly top-end pipes.

[holeshot19]

DUNCAN RACING got my 400ex pipe two year ago and it still looks brand new and flawless quality

You can not judge a pipe on peak horsepower alone. You must look at the dyno itself, some pipes might make 1 or 2 less peak horsepower but will alow the bike to rev 1500 -3000 more rpm, which ultimately will make your bike go faster in the end. You have look at what power curve will suit your riding best before using peak HP as the deciding factor. For instance if you ride woods or tigh trails, a bigger HP rating at a lower RPM would be OK, but if you like dunes and tend to Rev your motor, you would like a pipe that will allow your bike to rev more.

I saw their new ad in ATV Sport and they now have a lifetime warranty now.

[Foxrage]

I think im going to get a TC pipe....They are awesome low end pipes and thats what im lookin for

[Andy479]

tc pipes do give hellacious bottom end but they are like $530 + s/h.....thats nuts....you'd think they'd be cheaper since they use less materials since its a shortie!

[Foxrage]

I think they are like 320 for the 400ex cant see them being more for the 450r....if thats the case ill buy one for the 400ex and make it fit.

[sparky450AR]

that white brothers carbon pro is lookin pretty sexy to me, but the price is nutbogglng:eek2:

320 slip on, 530 full system

[Foxrage]

so they do have a complete system for a 450r now? I know they never had a complet for the 400ex. They always said stock headers were fine....slipon will work for me...L8er

I know what your saying I still have a couple more calls to make this week on some other pipes before I make my choice. I have been trying to get the low, mid and high rpm hp ratings on them like hmf is 7, 7, and 4 through the range which is great IMO also producing a ton of torque. As I find more out I will leet you all know.

[robby26wi]

baldwin has pipes and headers in stock...his own

[4FIDDYRHRC]

Whats up with the LRD pipes anyone got any info on them? Anyone got one? They say the more you do to the bike the more power they will bring on especially if you have an LRD pipe. :confused:

[Varmit57]

I had a LRD on my Built 440EX and loved it, Had tried a White Brothers and some off brand, the LRD was definatly the best for that motor. It had everything that you can do to a motor exept stroked.

Altough I'd like to hear from someone that put one on a 450r before I mke up my mind.

I will call them at the end of the week. I will post info on what they say they should have some #'s by then.

[sjw1176]

so does anybody have a pipe on there 450 yet

[granticimo]

I do have a pipe on mine and I have a duncan. I need someone to post my pics for me. give me an email and i will send you the pics of it. It looks good! It sounds good and it feels a lot better than the stocker with the hrc kit pipe.

ya whatever:blah: :p

i don't think they failed a single quad at Tx. and there was some pretty loud stuff there

[Varmit57]

I just ordered a White Brothers Slip-on to get by.


I think that I'd like to try one of Curtis Sparks full pipes when they come out....

what slip-on? we wanted a wb or some other one, got our 450r in Monday at the dealer and picked it up last night:D

[Varmit57]

"White Bros E-Series S-Bend Muffler,Fits 2004 HONDA TRX 450R ATV from http://www.motoxoutlet.com"

I've never bought from them before but I thought it was worth a try...

[sjw1176]

granticimo
email me at sjw1176@adelphia.net
so you have the hrc kit cam in yours plus the fat boy pipe, how was it to jet..... was the pipe alot better and louder..any info. will be great.

thanks,
steve

[400Ex_Rida]

That new wb carbon pro better do something special because $700+ is way to much. Has anyone heard of this new exhaust that gives the yfz 50% horspower increase? The advertisement is in the new dirt wheels mag. That would be a interesting choice for the 450r.

EARHHHH!!!

Don't even think about it bro! that guy is off his rocker. No way that guys are doing porting, flowing, jetting, new intakes, pipes etc and getting 55 HP total and that clown says he is getting 52 from just a pipe?! Please...

Maxx

[rebelxug]

I have mine with the HRC kit in it and I think for the time being I will stick with the replacement baffle that comes with the kit.

[Andy479]

Im pickin up my 450r this Sat. w/ the hrc kit installed. I have a HMF full exhaust ordered, do you guys think I will have to change the hrc jetting?

[FASTeR]

from what i understand from hmf's own site, it will definately need a rejet.

[Matt102]

No, no, no. The ad in dirt wheels is a pipe, port work etc. kit. I thought the same thing as you. You have to read the whole thing.

[FASTeR]

I did http://www.hmfengineering.com/honda450rfs.jpg

[4FIDDYRHRC]

What is the S/O jet?? :confused:

[FASTeR]

Slip on

[twisted threads]

so does anyone have any more info on pipes? My little bro is getting his R this weekend and were trying to figure out what pipe to get. How loud is the HMF??

[rollie]

WB -series or hmf

No, you will not have to rejet, HRC jet is 185 and hmf is saying 180 , should run fine.

[Varmit57]

Picked my 450r last night (SWEET!) and put the WB slip-on tonight and rejeted it...

I have to say that this thing rocks!.... and the motor is still stock!:D

I ordered a Hot Cams stage 2 for it, should be here tomorrow. That sould wake it up even more.

The dealer where I got the quad from tried to sell me a HRC kit for $299 but I got the Hot Cam for $130 and the Jet kit was $12. I replaced the pipe any way and it came with an air filter. For me I think it was a better way to go!

I would say yes. Just because the HRC kit has a 185 and HMF calls for a 180 doesn't mean you won't have to rejet. If the pipe makes more power you will more than likely have to rejet. You are allowing it to flow more than the HRC kit exhaust flows so you will need to richen it up.

[Fast450R]

I have the HRC kit installed & a Curtis Sparks Pipe & air filter is on its way. They said to set the pilot screw about 3 turns out, hrc needle in the 3rd clip position , & a 190 main jet. The person i spoke to is running this on his 450R.

exactluy what i was going to say....cant go wrong with baldwin:)

[Andy479]

I thought HMF made Baldwin's pipes??

[crap-banshee32]

baldwin makes baldwin pipes

[Andy479]

just looked on thier website, dont look like a HMF to me! $490 is pretty $teep for me though.
