I replaced the silencers with a pair of Sports silencers from Melvyn Rutter. A nice burble at idle, a nice rumble when decelerating without all the popping and banging I got on my 4/4 which I hated. At speed, yes, noisy but not excessively and no droning.
I agree about the front bumpers and spots. It suits the car. Not a cheap mod though.
I agree with Jays. I too have replaced the two silencers under the running boards with a pair of Melvin Rutter's sports exhaust and I'm very pleased. No resonating just a lovely burble at tickover and throaty on acceleration .
