I wondered if I could call upon the great wisdom of this forum to offer some measured thoughts on a single-pipe s/s exhaust system I’ve just acquired, please.
A peep down the silencer shows a solid baffle less than 180mm from the inlet pipe entrance with hardly any perforations (maybe 6 rows) ahead of it to allow re-routing of gases. I worry that back pressure could significantly impede airflow and inhibit performance. Not that the car sees anything beyond spirited road use. The vendor (a prominent international supplier of parts for British classics) assures me that this silencing arrangement is completely normal. It just doesn’t seem quite right to my untrained eye, so before I fit it, does anybody have any thoughts please?
BTW I know many on here endorse mild steel systems, but a quote I received from a recommended vendor was more than 3 times the cost of this and I just couldn’t justify it.
