2015 vxr8 gts

[10alex742]

Hi all looking to see if anyone knows the answer to a question I have, I have a 2015 vxr8 gts supercharged and it has the standard bi modal exhaust, on start up it sound great with the exhaust valve open but when you hit around 1400 revs the valve closes none of the cars modes leave it open past this is there any way of making the valve stay open all the time as I don’t really want to spend the 3k on a cat back exhaustwhen with the valve open it sounds great. Thanks
