Exhaust sound look performance ?

[luckyluciano]

So between Cobra 6 2 6, Rush, Two Brothers, & Basssani, which are the best based on above criteria? I'm leaning on Rush or 2 brothers for sound & performance.

What do you think?

Based on this sound clip it's Two Bothers. Maybe the go pro helped?

Check these TwoBrothers out from taxfree4..............that video is his installation. This video is out on an old airstrip. Just disregard the GoPro that has Parkinson's........I'll probably get these based on this video...:yes:

He's got the Torqloops installed so I have no idea how they would sound by just replacing the muffs...........probably damn close.

I took a 2017 B w/ 2 brothers ($1200 option) for a test ride. I do not care for the drone, it got inside my head. I don't think I could get used to it. I assume it do not have loops.

We have heard the exact same thing from several of our customers. What one person thinks is OK, it is not for others.
Without the crossover removed you are going to have drone to some degree.

Let's not forget there are variable factors which may contribute to or eliminate any drone or drone-like hum even without a crossover pipe i.e. type/ height of windscreen, shielded/non-shielded helmet, earplugs. Acoustically, there can be multiple factors which may/may not be the cause.

Whether the exhaust drone bothers you or not... removal of the CATS & cross over pipe will eliminate any exhaust drone completely.

What is the reason or cause for this drone? And do most bikes get it? I never heard of this before my F6B.

The best guesstimate IMHO is the way that the exhaust resonates through the F6B's cats and the baffles in the silencers. It's a harmonic issue with the way the gases pulsate as they make their way through the stock system; while at maintained certain speeds and acceleration.

Based upon demonstrated empirical evidence; the harmonics are further enhanced by type of helmet and selection of windshield; as well as rider's vertical positioning while on the bike. Many variables involved. One configuration normally is not applicable to others experiencing the cacophonous cacophony of noise and irritation to the aural senses.

That statement right there might make me keep my stock system!!! Too much cacophony goin' on.................:yikes:
