The cat on my wagon sport is well on its way.

Will i gain any better performance for by putting a De cat on it. Or is it not worth doing as its not a turbo.

you'll have 2 cats on there anyway matey.

depending what age your car is they will either be 2 separate pipes or one joined together.
This means you will either be able to replace the one that is knackered with a decat pipe and still sail through the mot, or you will have to replace both cats with decat pipes and either find a second hand cat or replace both your cats for the mot.
Oh and you should gain approx 3-5bhp for each cat you replace.

have a look at www.imprezasport.net for loads more info on sports

Cheers matey. One of my mates who works at the clinic said it could ruin the sound of the car. and another said i d gain more power from doing it. just needed another point of view.

Cheers pal.
