Well done, guys - sounds awesome. How much to do same to '04 HSV Clubsport??

[ringram]

Both sound nice.

Any idea's on power loss between quiet and loud?

[wortec1]

No loss of power between the two settings........

[maverick964_uk]

top drawer guys!. Very informative.

When can you get down to Picador and set mine up with the active option on the exhaust.

Pretty chart

From where was that measured? Normal static trackday measurement as I remember is 0.5m @ 45 degrees (from the exhaust tip).

Yes, standard track day static position..........we want to do "drive by" as well but there is no official set up for this.

does the R8 in the video have the 20" wheels?

[maverick964_uk]

also where is the switch mounted for the active exhaust?

[quote=wortec1]Yes, standard track day static position/quote]

So at 4950RPM (about 3.4 revs) 95dbA loud or 86dbA quiet. So loud will still be OK for trackdays, unless it the driveby is an issue (e.g. Bedford) in which you can switch to quiet.

My old Caterham Fireblade was 96dbA @ 0.5 @ 45 and that was just about right for road presence without being totally antisocial.

So on paper that looks really nicely judged

Yup

[maverick964_uk]

does it have the lowering kit too?.
Are there more of a darker silver finish?
What is the ride like with those lower profiles tyres?

[greens vauxhall]

Std springs, wheels are shadow chrome finish (as old VXR) and ride quality feels no different.

[maverick964_uk]

got some pictures showing the wheels off???
these are the ones off the GTS yes?
