why would you want it to backfire?? the rlly car won't be backfiring, it's prob turbo'd lol and thats the pressure from the turbo booting out! who knows, do you have a vid of this rally car in action!

The main reason a car backfires is because a valve is not closed when the spark plug fires. If it is an intake valve, it will backfire through the intake. If it is an exhaust valve, it will backfire through the tailpipe.
There can be several reasons for this. The valves are adjusted too tight. Valve stems can be slightly bent and not allowing free movement up and down. Or the ignition timing can be off. There can also be dirt and sludge buildup that is causing the valves to stick.
Backfiring will also cause you a loss of power but if you want that then pm me and i'll tell you how to fuck your car up............ but make it backfire!

its not recommended dude.

remember le saxo on your drive is not the saxo on a rally track. Just concentrate on the proper mods and it'll run sweet as a nut and wont need any badass backfire. pow pow.

would advise induction kit, exhaust, manifold, decat, cams and a re-map. depending on the cams and how its mapped your looking at around 150-160bhp matey, don't do anything else to the ECU! especially a not so 'superchip'!

tuning mods to make it back fire easy:

1. turn fog lights on 10bhp
2. lexarse lights 5-8bhp
3. neon lights are the best as they add 15bhp
