Buddy Club Spec II + Helmholtz? - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Ok so I originally got the buddy club exhaust as sort of a temporary thing till I could order up the nameless axleback and downpipe. Well and I was curious to see how loud it was and how it sounded... Anywho.. After having it for a while iv grown to like it quite a bit. My question is to you guys that got the nameless downpipe with the Helmholtz resonator. How well does it cancel out drone? I know it will be louder but do you think it would kill off a significant amount of drone from my super droney exhaust?

After reading some stuff about Helmholtz resonators (not only in relation to this car) you are coming to a conclusion that this thing in the mid-pipe is rather for eliminating unwanted "drone" produced by the header and has little-to-none impact on everything after it in the exhaust system i.e. axleback and its muffler... But that's just my current impression from reading different forums. Would be also interested to hear from someone who really knows how these things work and sound - such as Jason from Nameless.

Yeah see I had heard that some of the cat backs more prone to droning had benefited from the Helmholtz being in the system before it. Yeah I'll see what Jason has to say about it
