I guess the only problem that might be effecting performance would be the bottle neck effect at the stock muffler because everything else is 3" pipes. Once again, AFAIK, only stock, OE mufflers are alowed for saabs here in Germany. Thats why I have to have the original muffler on the car. Not my choice, just the LAW!
