Someone with just the Akra slip on could chime in and state otherwise, but based upon what I've read/heard I just don't think you'll get very much out of the slip on alone. Inside the cabin, engine noise will overpower the exhaust whenever you get up in the revs. Akra designed the exhaust to work as a full system -- from a performance and sound perspective.
M performance on the other hand was engineered to work with the stock mid section. Axle back alone I think it's a much fuller sounding exhaust.
