Id go with the Akra system. They both make great power with a tune. Id give the Akra a slight edge.

Akra for sure...fit, finish, power...yosh isn't close to the same quality. Posted via Mobile Device

Nothing at all wrong with the R77, but I'de go with the Akrapovic. I'm going with the Akra full dual cf on mine soon, and the muffler is shorter and fatter on the Akra full single(black 11 is the full single). Neither pictured is my bike.

Yes I agree, I like the single short stubby can look on the Busa. Any idea how loud the Akr is compared to the Yosh R77

Where do I post for a sponsor here to give me the best price? Is there a certain section I post asking who will offer me the best deal on the system?

Thanks

MotoMummy has the best prices I've seen on Akrapovic, 58 Cycles prices are good too. Akrapovic and Yoshimura both have baffles/quiet inserts(most mufflers do)that will quiet them down 2 or 3 decibels. Akrapovic is not a loud exhaust and neither is the R77, baffles or not. If you want louder try Two Brothers, their Black series cf mufflers look really good.

I heard an Akra full system on a new R1, all I can say is AWESOME! Sounded like a true race bike.

Motomummy good prices? 1399.00 :cookoo:

The best I have seen is $1112.39 to my door

Unless a sponsor here wants to help a po boy with a motorcycle payment??

I have the R-55 and if I were to do it all over again I think I would go with the Akrapovic. Beautiful sound and quality!

They've went up dramactically recently then. Them and 58 Cycle both had the full single cf for under 12 and the full dual for under 16. 11 shipped is a great deal!

I have the r77 slipons because I really don't like the look of the single can on a Busa and I couldn't buy a full dual system at that time. Were I looking at both Yoshi and Akra though, I'd go with Akra every time. I love their new shorter, stubby cans.

I buy all my stuff from MM Corey is good peoples I like Akra but went with the R77, Dual exhaust is about as played out as Charlie Sheen's career

Akrapovic is a better made product imo. It also sounds better and deeper as I had one on my GEN 1 which previously had a yosh. The Yosh brand name is like going out and buying a Tommy Hilfiger shirt.....it use to be the **** before everybody got them and the market was created and people started producing better products

  Anyone running the Akrapovic Racing FULL Exhaust System 4-2-1 on a GEN2

Yes. Below 8k rpm it is quiet-ish, above that it speaks to my soul. I believe the power delivery is slightly better than the Yoshi, but that is barely perceptible.

Post directly on sponsors sections or put (ATTENTION SPONSORS) in the Heading when creating a thread. They will most likely chime in within a few minutes.

Looks to be a good deal in the classifieds section for a yosh system.
