Hi there,
I've seen on a youtube channel a review for one Astra J OPC from Netherlands which had valve exhaust system installed , the man sad that everything is on 3" , deleted cat, deleted middle silencer, no brand exhaust or similar.
I wonder if someone here installed such a thing and how it was connected, as far as i know that valve needs to cut off one pipe and let another free, but VXR has only one pipe until the backbox
I've asked the guy on instagram he said he would send some pictures on how he did it but nothing yet.
I have the same setup on 3" pipe with only backbox but it's a little too loud, and police doesn't like that, was looking to either fit a valve system or install a sport silencer after the downpipe.
