VXR8 with Walkinshaw - drone :-(

[SteveMJ]

I had a a Walkinshaw sports exhaust fitted at the end of August (thanks Rich24 :-) )

I find that there is a bad drone from 1600 rpm to 1950 rpm which corresponds to 50 mph to 70 mph on a Motorway for example, or in urban traffic. The auto-box tending to hold the revs around this range unless driving hard; in traffic most of the driving is light throttle

I use my VXR8 for a daily 90+ mile commute so spend much of that at light load so get a lot of this drone! It is reducing my pleasure of the car and V8 soundtrack.

Any suggestions would be appreciated.


Thanks, Steve
