Anyone know any mods to give more power/torque/response etc. that wouldn't affect the warranty? I've got the WR back box, but is there anything else? Preferably something that makes it drink more petrol as 18 mpg is far too economical!

hear hear !!

Depends if you've got a sympathetic dealer.

I know of people who have the replacement downpipe and are real pleased with the results. This can also be fitted in conjuction with a replacement air filter.
