Yoshi and PCIII?

I'm interested in getting the Yosh slip ons, but don't really have any desire to get a PCIII with it, for those who have the pipes sans PCIII, how has your performance been, any issues?

Thanks- I did a search and couldn't find many comments regarding this..

I have an 05-919 with twins yoshi pipes, no pc III... The only thing I needed after than was a set of blocking plates from a member of wt.
Runs fine maybe a little to quite for some....
no issues to date, it had 2000miles a year ago when I got her and now 5400, no problems....

Blocking plates fit on the top of the cylinders, one per side on the front. I think it was SemiGray that provided the well machines blocking plates. It replaces the smog stuff. Look in the mod section there is a write up, or do a search here....Also stops the backfiring on deaccelation....

Yosh slip ons

I have a set of Yosh slip ons they are ok. When you take the db reducers out they are loud but I also lose alot of power so it becomes a loud slower bike. Is this common with yosh slip ons?

Yoshi site states no alterations required to their slip-ons.

Does anyone know the diameter of the opening on the Yoshis? I want to put a dB reducer on my D&D, but they don't make one. Hoping I could use the Yoshi reducers...anyone?

Which cans do you have? Turn-down-tip? PCIII? I have the newer version CF TRS without the turn-down-tip and have not bothered to install the db reducers, might they help performance? (I have a PCIII)

Attached is what's currently shipping with new cans. Mind you, they done have the turn-down-tip, so the opening is just a 1.834" hole in the end cap. The large flange you see is 2.319" in diameter and retains the insert behind the end cap (which is removed to install the insert). The actual pipe that the insert is made of is 1.253" outside diameter, and roughly .665" sticks out from the flange 5.739" behind for a total length just over 6.5". It does taper slightly in the last 1.665", to an outside diameter of 1.086".

I hope this is helpful, I don't know what the inserts look like for the turn-down-tip version.

If you dont mind me asking what you pay for your yosh pipes? I really like the CF ones but there very pricey, even the ones on ebay are way up in price.

The best price I found was at biohazardcycles.com and I'd been looking for about a year, $630 shipped. They list on eBay but I went the conventional website route.

I have the stainless newer version (without) turn down tip. No pcIII and stock air filter. Its the insert if removed for louder sound just seems to make the bike slower.

Interesting... I'll have to play around with some different configurations. It has felt like I am needing to down shift more often to pass but since our riding season is so young and I hadn't ridden since last December (before the can swap) that is was all in my head. Maybe now.
