Is this what I need?
 

I am wanting sometime hopefully soon to change some exhaust parts on my 03 blob WRX. At present I have a Revolution backbox and a centre section I think (resonated or de-resonated I have no idea, its just a straight pipe :wonder: ), it joins onto a CAT looking thing about under where the gear stick is and has an oxy sensor sticking out of it, but now want to get rid of a CAT or 2 or 3?

I was on Revolution's web site and saw these Revolution the upper high flow CAT at £299.99 and the Lower downpipe no CAT at £119.99.

Just wondering if I've got it right and if these are the bits I need.

Oh, it HAS to be MOT friendly.

If I could figure out how to put photos in threads I would show one of under my car so you could see whats on it.

Thanks.

Anyone?

At least one reply would be helpful .....:norty:
