I just read the thread questioning about yoshi exhaust slip ons....This arouses my curiousity, I have pretty much decided on the yoshimura carbon fiber pipe- I watched videos on all the different exhausts and like it's sound the best, why would a muffler come without a baffle is my question? Also with less restriction (the baffle out) wouldn't that mean more power? I am curious as to why something in the pathway of the exhaust could give you more power.... this coming from my knowledge of cars of course. I have a turbocharged supra and it has a full 3" exhaust and a big open HKS carbon ti muffler, which gave it a good 25-30hp opening it up like that, but it is a turbocharged car. I am in the dark on bikes. I do love a loud a$$ pipe on a bike. also will I truly need to jet the carb to get the best results on the small power gain and running properly? some say yes, some no (more yes). But I have no prob. spending a few extra bucks to achieve better proper results. One more question where do you get the exhaust gasket? Thanks again peeps, I appreciate you guys helping out a newb

I did have some questions in here fellas, thanks!

Back pressure will give you more low end power. Higher flow gives you more top end.

Both are limited by the air/fuel mixture and what the engine will allow to flow through it.

For the Katana, the largest part of restriction on the flow of air/fuel through the entire system is the motor followed by the header. The kat cams are very mild. Swapping the cams from like a GSXR around 89 model, adds alot more air flow so you can see more gains, but there is still only so much that will flow with the header.

Carbs are natrually asperated, so they only will provide so much flow based upon what the engine pulls through.

A turbo increases that flow by forcing the air/fuel mix into the engine. A larger outlet on the back side would probably mean more can be forced in from the front size.

Ultimately, the carbs are tuned for the flow you have. If you increase that flow, you need to rejet the carbs to provide the fuel needed. They are very sensitive, and so minor changes like a new exhaust can which has a small effect on the flow can lean out the air/fuel mixture.

That being said... the differnce between a restrictor in or out could be simply the difference of "lean but running" vs "too lean to get proper burn" and loss of power.

Hope those very generic and general answers shed some light on it.

I like my V&H exhaust. sounds great

there, fixed it for ya.

also, its Yoshimura

I also have a V&H SS2R...looks great and sounds fantastic without being overbearing.

exhaust

i too hace a 2005 600 kat i first put a d&d slip on and the sound was horrible. so i went with yoshi and love it. it gives a good resonance sound.sounds close to a low end rumble to a fast and furious car. i hope this helps.

you can do a google search . i found a vance and hines full exhaust for a 98 -600 . for only $320.00

If I do sway in the direction of exhaust, it will be yoshi, thanks guys

i bought a D&D for my 750. it's LOUD and the cops are running to find you from the other side of town. great for track days.
