Yoshimura Signature vs Street R77

Slip ons are really known to make no extra power , and more than likely to loose power compared to the original stock mufflers . Yes , they look better , but bro , get yourself a nice full system , maybe a 4-2-1-2 like an Akrapovic , and a good tune . Would be real sweet on your grey sweetheart !!

More looking for the sound and weight savings. I also do not want to mess with my warranty. I had Delkevic on my black one which were ok but I thought I would go with Yoshimura this time.

Sticking to one bike or will you be getting something else to go along with the Busa?
They look exactly the same but the Signature just flows a little better due to internal design, according to Yoshimura. Now that my son is running his 4 into 1 Akrapovic… they are the way to go if you can deal with the one sided look which is kind of my only issue.
Yosh for the win, Suzuki and Yoshimura have had a long relationship and know how to compliment each other.

Sticking with this one Busa.
You will gain a bit of power even with slip ons…the stock cans are very restricted whereas the Yosh (or aftermarket) cans are not...all one has to do is look at the size of the exhaust tips in comparison.
...and you save weight which is like adding horse power.

I called Yoshimura this morning and they said the Yoshimura Signature series has an unremovable baffle and is therefore stamped EPA and CARB compliant. Yoshimura Signature series is not much louder than stock.
The street series is only CARB compliant and is louder than the signature series is not much louder than stock. It has a removable baffle.

I've spoke to Yoshimura as well. They pointed out that the only option for Hayabusa is their Signature Series.

They have both street and signature available. They are also on their website and ebay for at least GEN2 Busa's.

In other words the signature series is for those California guys lol

That's what it sounds like. They are an EPA approved replacement muffler.
No one is checking our motorcycles exhaust for CARB compliancy.

Good to know, we have inspection in NC yearly but it’s only light, horn, signals, mirror tires etc nothing emissions related

We have nothing in Georgia. Pay $20 and be on our way.

It’s like $13 for inspection here which you have to get prior to a plate/tag renewal

I actually didn’t like the one sided look, until I actually started riding correctly. Now I won’t ever go duals if one side is an option. Also cheaper.

No inspections here ever for motorcycles, cars once every two years have to pass a smog test but that’s it.
