When I got my 914 it had a Monza free flow exhaust. The 4 tips pointed up at a slight angle. Looked cool but invited water ingress. Rusted out. Replaced with a Bursht tuned exhaust. Didn't look as cool, tuned made a teeny bit more power than free flow, and never had any rust issues. The only issue with the Bursht was it got the left rear valves hot and had to re-adjust them every couple of months.

When it was all tuned well it would go 0-60 in 9.5 seconds. Otherwise it took over 10. Don't know what it was but after Dumont's tuned it I always had to reset the dwell with my Sears timing light to get the 0-60 under 10.
