Tyre Roar -v- Exhaust Scavenging Resonance
The exhaust scavenging resonance is not intrusive when you drive on B’grade coarse chip bitumen – esp. when it’s the older & coarser type. Roadway roar drowns out the resonance just nicely. Although, I’d rather some exhaust resonance than tyre roar.
If the resonance is that concerning, perhaps a modified exhaust system could be an option.
Having said that, I’m always amazed how guys pay big bucks for ‘custom exhausts’ only to find it mucks up the scavenging, reducing the vehicles performance. The word ‘custom exhaust’ does have a nice ring to it.
Cheers.
