I’ve just sold an aftermarket exhaust. It was very well judged with regard to sound and was quite light. I removed it when I converted the car to standard in order to sell. But life got in the way. So I will wait until next spring now. Anyway, I decided I actually like the standard set-up better. It means you get a totally undistracted (is that even a word?) sound of the intake and the rev matching just felt sharper.
Sorry, I know you were after recommendations. In which case I’d say tubi. If you can still get them and don’t mind the 2500rpm drone. I don’t like taitec. They look cheap and sound unrefined. Fujistubo sounds like a good bet. But apparently cheaper from JP. Although torque GT sell them.
