Pipe for 2006 TRX 450

[gal22279]

I am looking for a pipe for my 06 TRX 450R. I have been looking at the following brands.. Curtis Sparks, Rossier, Alba and HMF. Any insight or suggestions?? Thanks in advance!

DASA, Rossier, Rage, Yoshi TRC, or Ron woods (if you're a duner).

You forgot Sparks...very good bottom to mid range a great top end. Just a good all around pipe

The Sparks does not even compare to the DASA, Rossier, and Yosh TRC.

I know its a popular pipe, and many run it, but dyno numbers don't lie.

You can search this site and come up with 1000's of results on which pipe everyone likes.

Sparks has very good numbers and many people run them. And how does it not compare to others:rolleyes:

Sparks: http://www.wppracing.com/images/spk600.jpg
44.95hp , 30.52 torque

Rossier: http://www.wppracing.com/images/re600.jpg
46.80 hp , 31.69 torque

Same exact bike, with the same exact setup, just a pipe and jetting change to get the A/F ratio's the way they should be.

ENJOY :).

Is there a graph for the Big Core???

Nope...this is a stock bore machine. Just like most people around here run.

"the big core is not recommended for stock motors. Your bike needs to be "ready to race" to see it's benefits (i.e. aggresive porting/bb/stroker/large cam)"

In other words, if you're build doesn't meet the above requirements, all that big core is doin for ya is making more noise. At least thats what I've heard.

To each their own.

I have heard some sparks pipes, and I will admit that they sound great.

[400exrider0004]

Yah they do sound great. Actually I didnt know about the big core thing and how it would be recommended to run with a race type motor. Thats good to know.

i just got a sparks big core for my 07,i have not yet installed it but man its sweet is powdercoated candy red and i have to say its fit and finish is the best ive seen.pretty sure the big core makes em pull harder on top end and are alittle louder,most people i know that have them only have the hrc kit,and thats all iwill be doing to mine hrc+sparks big core.guess i will find out,pretty sure i will be happy.

How does the rossier compare to the DASA?

[ghott]

They are extremely close.

I have yet to see any tests done on the 06/07 bikes...

But on the 04/05 bikes, the DASA outperform the Rossier by a small margin all accross the power band on every dyno graph I've seen comparing the two.
