I remember coming across a post on the e55 forum. And one of the guys had pulled I think one of their resonators. I haven't got under the car but apperently the s55 has 2 sets of mufflers and cats/ or resonators. He mentioned the change in sound, obviously, but the preformance aspect of it, after all it is a blower car.
Will this through a code?

 

Hey

The removal of the resonators will not throw a code and actually (if it is dones correct) will not resonate in the cabin



This E63 also has an Eisenmann exhaust and at idle/ at standstill it is very calm

 

Removing resonators will be fine with no cel. Start messing with cat is were problems begin. I planning on get rid of mine also, if I do I will post a clip.

 

Looking to getting rid of mine on my E55 but I don't want to make my car sound like my old Saleen's... so with the stock exhaust what does the removed Res. sound like? So, what's the cost and anyone know of a good shop in So. Ca...

 

Post this on the E55 board. I know there are alot of guys in the so cal area that would recomend a good shop.
