My 04 BCGT sounds fantastic for the first 30 seconds after startup and also under heavy acceleration but not so great when the exhaust bypass valves are closed.
Anyone worked out how to manually open the exhaust valves ? Would like to have them open when blasting around a mountain road etc.
Looked at the Capristo system for $1,200 but it is total overkill for what i want.

Can i wire something up to the electronics ? Or do i need a vacuum based system to bleed off the vacuum ?
If i hook up a simple vacuum bleed off system, will the original sytem keep on operating to try to close the valves ?
Any advice gladly accepted.

You can unplug the vacuum hose on exhaust valves n plug up hose. She will roar non stop for u afterwards.

 

I know that - I am after a way of switching from stock to fully open wihtout crawling under the car - a switch or a remote is how I am thinking.
