As per title, and also is this a good idea?

Thanks,

Same years? What are you hoping to gain?

Yes and not worth the bother.

Just put an exhaust and filter on your car and get the current ecu mapped.

I figured it would be a cheap, insurance friendly way of getting some more performance.
It would be off a 2003 and mine is a 2004 (both Wrx).

Is this because a remap would be better performance wise? If the above parts are circa £250 is it still not worth while? I have been advised a remap is 500 quid alone.

An open source remap is £300.
You don't need to tell the insurance company its been mapped or has a fancy panel filter and most won't increase the premium for an exhaust system, but you will need to notify them.

A custom remap is a far better option than the rich generic map you get from the ppp ecu.
