Ive been told id get good power increase by taking off the front cat on my 95 wrx, whyat exactly do i need to buy to replace it?

 

You need a de-cat down pipe.

Make sure you get one with a bell mouth, a great deal less restrictive than others that have a flat mouth.

I'd recommend a Hayward and Scott item. I bought mine secound hand off eBay for £75. New I think their about £195.

A very good mod to have.

 

you need a de-catted downpipe mate.
