So the main reasons that I want slip ons is to get more of a Harley burble (as much as you can with slip ons only on an M8 engine) but also to increase the sound, not super loud but just so that I get to hear and enjoy them whilst riding. I don't really hear the exhaust note a great deal at the moment (stock pipes) and can hear the actual engine noise and gearbox more. Obviously I know that you hear more exhaust note behind the bike, but it would be nice to hear it whilst riding too.

So I've gone round and round between the Vance and Hines Twin Slash and hi output, although tbh the hi output are out of budget but IF they are the ones I want I am prepared to wait. From listening to numerous videos (I know not ideal) I do like the sound of the Twin Slash better, especially at idle. I like how they 'burble' more and sound as though the bikes only just ticking over. I also think under load they sound more 'traditional' whereas the hi output have a slight 'race' sound to them. So I thought I was dead set on the Twin Slash but then I hear a lot of people saying they're not loud and no louder than stock, although on the flip side some say they are louder than stock just not obnoxious.

I was under the impression that the hi outputs were louder but I contacted V&H yesterday and they told me that the Twin Slash are louder than the Hi Output which took me by surprise, especially when I listen to the video I've posted below where the hi outputs sound louder and more aggressive to me. The video also demonstrates the 'burble' on tick over on the Twin Slash I'm referring to.

V&H also threw another couple of pipe into the equation that are the loudest slip ons they do, the Eliminator 400 and the other I've forgotten I also asked V&H about the sound level at idle, and they told me that no pipe is loud at idle unless you change the cams.

The Eliminator are a similar price to the Twin Slash so they're do-able, but from videos I think I still prefer the 'burble' of the Twin Slash.

So long story short, I think I'm going to have to take a punt so what I want to know is whether the Twin Slash and Eliminator 400 are:-

1) Noticeably louder than stock but not obnoxious?
2) A fraction louder than stock but not that noticeable?
3) No louder than stock just a deeper tone?

Any advice would be much appreciated.

West End Motorsports and John Maxwell both have extensive touring exhaust comparisons posted on their YouTube channels. That may help you decide although nothing beats hearing them up close and personal
