@orthojoe wins the day for the best most informative and succinct post.
it's worth noting the dundon center muffler has been tested with a '15 GT3 @ laguna with side deletes and passed sound at a 92 db day.

Granted the biggest sound deadening unit are the sides vs center muffler but if you have valved side deletes and force the valves (with a gps device) you'd still be passing the exhaust through the longer route of the center muffler so it must have some affect on sound level??

I'll add that if you have side muffler deletes, but they are valved, the GPS box will still do something since the exhaust flow will be traveling a longer path through the center muffler, but you would still have no chance of passing a 92 or 90 db day on an otherwise stock exhaust.
