Quiet 70mm single exhaust needed!
#61
Steel will dampen sound better then Ti. But see its a conundrum, light weight means thin walled tubing or material that magnifies sound, so quiet and light weight are in a direct conflict with one another. You might be able to find a happy medium that works for you, but I’m afraid you can’t have your cake and eat it all too.
And pretty lame a race track has noise restrictions, that’s a bit of a conflict of interest in itself

I am running a Forcewerkz Track exhuast. It is incredibly silent! It looks like a ASM Can with the same design as the EVS 70. To channel sound away at low RPM but then opens up around 4500. It have a deep grumble sound.

however, I also haven't heard anything about the power or the sound either
can you comment on how loud the exhaust is? not anecdotally, but with some kind of quantitative values - even an iPhone with it's internal dB meter?
how bout power? anybody with a before and after dyno?
how was your experience with fitment? are you rubbing or melting or anything?

I got a 101dB reading with my T1R 70EM single, toda header and test pipe. They measured at around 10m (33ft) on WOT drivebys.
The same day there was another S2k with a J's 60RS that passed the 95dB limit, he did have the resonated T1R test pipe though.
Stupid noise limits
