I’ve done loads of motorway trips and there’s absolutely zero resonance in any gear too.

I was unsure about it when it was first fitted, but over the last 4-5k miles it’s really settled in and I’m liking the noise now.

Well worth doing, and it gets rid of the hanging ball sack...
Thanks for clarifying.
Which would you say has a deeper tone? Race or EL
I plan to use the bypass tubes.
