I have to admit that a V6 has a certain appeal as well.
When I were a lad,there was a bloke who had a custom MK2 Cortina kitted out with a cologne V6 and no silencers,just a straight through set of pipes-IIRC they were something like 3inch bore.I remember him telling me he used scaffold tubes....
You could hear that car from just about everywhere,especially when it was on throttle.
One of the guys I work with had a Vectra V6 with some sort of sports exhaust fitted.It was a nice sound but a sh*t car!
