Thread, I command thee to arise from the dead!
Thought I'd bring this thread back to life as just read through it after a chance meeting with Stan at ecotune during my lunch break. Went to a local place, C&C custom exhausts to see about getting my droopy tailpipe replaced and it turns out they share a workshop. So, went in to get a cheap cosmetic mod and have now left with plans for DPF removal pipe and a remap along with said new tailpipe. The guys at both companies were great.
The price offered was amazing going on what I've read here but I guess it may be cheaper for a humble 318d.
If anyone wants to know about the issue of whether or not there is more smoke then have a wee read at this thread where it gets explained. I don't actually understand the explanation to be honest.
