Boring '6/Rallye MPG question

[Piggy]

I've been quoted £900 for an LPG conversion in one of these before, that should take about 9 months to pay for itself. And Piggy, its not speed alone I'm bothered about, its the noise to go with it

thats very cheap, that would concern me.

I am fully trained in LPG systems fitting, and was trained by the UK importers of LANDi, they are now in serious high end stuff, evos, porches, etc...but there are still little places out there doing crappy polish kit, single point, venturi stuff....its horrific.

for a good reliable kit with a valve saver system, I would expect £1500 min.

And as for noise...get ya self a GT series turbo, a straight through pipe and tell me you dont like it!
Plus I cant see how you wouldn't like the sound of a 600 sports bike at 14000rpm!
