with a standard bore and 11.1 compressin stage 1 cam k&n filter and jets would i be able to tell a big difference between dual exhaust and my yoshi pipe? where can i find a dual exhaust for a raptor i have done a search but no luck ..

 

Tim Barker sells dual pipes, and so doesn't Looney Tune Exhuast. Both system's give good gains.

 

Speaking of which, has anyone gotten a good dyno run on the barkers and another pipe? Just looking for a comparison to guage the credibility of the claims.

 

If you shoot a email to kenz cycle tech they will have some info for you.


I'll have some dyno runs on the Barkers around April 1. So maybe I can shed some light on what my raptor is making at the rear wheels...but I have no other pipes to compare other then the seat of the pants....

 

*This is my mandatory post I always post in threads of this nature to say I have the Looney Tuned Exhausts*
Ahem,I HAVE THE LOONEY TUN...ah well you know the rest,LMAO!!! [img]i/expressions/face-icon-small-happy.gif[/img] [img]i/expressions/face-icon-small-happy.gif[/img] [img]i/expressions/face-icon-small-happy.gif[/img]

 

ive seen the barker duals in person make 1 more horsepower than a sparks pipe, thats on craycraft 686's though. 10.75:1 comp. they are pretty equal pipe, both are excellent, ive seen the barkers make some cheasy quailty pipe though, but it is getting better, ive also heard teh lts give a little more torque. the bike that won fsws was running on the lte's, both are great duals though, the barker is more of a drag pipe, you wont like it for everyday riding.

 

yup....the Barkers are a great high end pipe...alot queiter than a Sparks by far.Also the quad than won in that Martin Luther King weekend race was a stroker and is now running the Barker exhaust.

 

Kingraptor dynoed his Yoshi versus the Barker's. On a low compression Kenz 727 the Barker's made an additional 4 RWHP.

 

Probably not. I doubt the Yoshi would be much of a restriction for that engine combo.

 

I also have the dual exhaust system from Looney Tuned Exhaust. I am really happy, infact we have the system on all our bikes. Check them out at lteracing.com
