You can get backbox fitted only, for around £120 at the cheapest
Full catback good quality varies from 600- 900 and anything up to 1200 for a Turboback

Forgive my ignorance but what is a turboback?

New exhaust form the turbo back to the end of the car so new catalytic converter, mid silencer and back box along with all the piping. Cat back would be from the catalytic converter back using the same catalytic converter.

Cyclone beat me to it.
The turboback new catalytic converter would be where the main power increase comes from- between 8-9BHP for the new Cat on mine, alone
Then 2 or 3 BHP for the remainder of the exhaust

A new Sportscat makes the engine feels like its been released from its shackles. Had one put on 500 miles from getting car new
