YRV and Sirion M100 tailpipe

Bob, I was going to have to replace my exhaust system very soon as the pipe just in front of the silencer was about to rust through and silencer forward is one-piece. This happened at 4 years and now at a further 6 years. I bullied Daihatsu into replacing the first system for free outside of warranty. The first system had a straight pipe outlet and looked boring. The full replacement Daihatsu system had this 3 inch rolled-in stainless end which looks a bit interesting.

The new stainless system has the same type of outlet. Two straight-through baffleless silencers are fitted, one in the long front run to replace something that looked like a small silencer and one in the usual position at the back. This provides a very quiet system, at least inside the car, which is what I wanted.

Even though the very experienced and excellent TIG welder who did this job used to work for Renault F1 I didn't want any messing with the lambda sensor and its shroud, so a flange was put on the stub front pipe after the sensor.

Am I happy with it? Well, yes. The system is beautifully made and....bless my soul, even after a few days there is absolutely no sign of rust, which was the only reason for changing the system anyway.

There may be some benefit from the freer-flowing exhaust, perhaps a slight power increase at high revs which I probably wouldn't notice, or a slight improvement in the already impressive mpg figure.
