Went to a local exhaust
shop that did it in 15 minutes for 20 euro. They used a 65mm pipe that was tapered so the two cut ends where the resonator had been fitted perfectly.
Sound at idle was slightly louder but when driving you could now tell the car was announcing itself. For those that like a louder exhaust it was a nice note with the stock muffler still doing an excellent job. Droning in the car is to be expected but in the front not too noticeable though back seat passengers might have a bigger
problem.
