Put in an electric cutout on the dp, pre-convertor....You then open it up when you want free flowing and then close it when you dont want noise. Pretty simple and inexpensive? My friend has used a cutout on his 1G forever, he still has the stock exhaust on it? opens the cutout and away he goes....and his car is over 400hp, other than the front mount you would never know the car is fast, it looks bone stock down to the factory 90 wheels....

summit sells one, its on backorder until end of this month I think....but its the best built one out there with a 3 year warranty....cant beat it
