Hi,
I'm part way through refreshing my rear subframe bushes. Its a tougher job than I expected as everything is rusted solid and stuff like the brake back plates all need replacing. Anyway I'm making progress even if it is slow. Well that was until yesterday when I discovered my exhaust system from the manifold backwards had been stolen
I was horrified when I looked at the cost of a new system from BMW -circa 2.5k and the middle section isn't even available any more... It is a year 2000 Z3 3.0, this model seems to have 4 cat's- 2 on the manifold and 2 in the middle section. However there is no 02 sensor after the second pair. Unless anyone knows of a second hand 3.0/2.2 OEM system for sale I'm going to have to look at an after market system. I have a couple of questions...
1/ Does the car really need the second pair of cats or could I get away with silencers instead?
2/ Can anyone recommend an aftermarket system that is similar or only slightly noisier than the oem system? Prior ro this i had a 325i and when the rear silencer went i replaced it with a powerflow silencer, it ruined the car! There was a horrible resonance about 50-60mph and I want to avoid this.
Many Thanks
David
