Ya, no big -- that's why they make so many different types. I do tend to doubt claims of 19lbs saved with a full exhaust. The stock headers are light -- it's the up tube and brick-like muffler that's heavy. If a full system drops 19lbs then ya gotta wonder how thin those tubes are and how long they'll hold up to heat/cool cycles.

I've had great success with 2Bros on all my bikes. When my Busa was mostly stock it made 162hp on dyno. Adding 2Bros full exhaust + PCII and small tinkering with the valve clearances yielded 174.5hp on same dyno. Had similar gains with a jet kit and 2Bros slip-on on an old Kan-a-toona.

In the end you gotta decide what you like best.

 

yeah, on second thought, ive had it with full systems and pc-ing bikes. i might as well just get a slip on that looks awesome. like the cbr needs any power anyways...

 

sato makes a great slip for the 1000rr. when you have a full titanium system its going to drop alot of weight period. the honda headers are very good to begin with so if you end up getting a good slip on it will save you some money.

 

I've recently been looking at the blueflame slip-ons as well. They do fit the under-exhaust style well, and I hear they're made well. Now that I see they sound good too, i might go that route come spring/summer. Anyone have any thoughts on Yoshimura exhausts ?

 

Yoshi = good

 

thanks for the comments guys. yosh exhaust looks weird, kinda like a dried out opening. hahaha

 

I tend to disagree. I'll be installing mine either tonight or tomorrow night.

Oh by the way, I also have two brand new Yosh slip-ons for sale if anyone wants one.

I have 1 stainless and 1 titanium...prices will be very good I guarantee!

Shoot me an email if interested todd@thecyclesource.com

 

nice plug for your site hehe

 

Guys - my first post.

Just installed my Yosh RS-5 slip-on on my CBR 1000 today. The pipe connects below the exhaust control valve, so I took the controller, cables and servo spindle off the bike. After my scoot around the neighborhood, I thought there was a slight burble just off idle. What do you guys think? Should I try to fabricate something to put the exhaust control valve back? Does everyone remove it?

 

Leave it off. Burble could be low idle due to loss of back pressure from factory restrictive can. Too much slack on throttle cable can also cause off idle burps.
