More sound basically.

You will more than likely get the engine management light on, because the post cat lambda sensor will see too much exhaust flow. You can get a spacer to bring the sensor out of the flow more to trick it.

Not sure on that one. I had 205/55/17 fitted to my old Vectra, and swapped them for 225/45/17 and never had any problems. **

1) I've tried several setups on my 2.2. Best performance was standard air box with larger intake scoop and bottom half De restricted.
2) as post above
3) as long as all 4 tyres overall circumference is the same you won't have any issues. Just remember that speedo may be out if you deviate from stock sizing.

What is a spacer??

MikeS

like an extension to the lambda sensor but the sensor actually sits outside the downpipe
