Im thinking about fitting a de cat downpipe to my93 wrx. My existing pipe (cat) i believe is leaking (if i can use that terminology!!) as when i had some brakes fitted it wa on the ramps and the burn around the joint wa noticeable. Is this a worthwhile mod and what change in performance etc can i expect?........cheers

Yep did mine about 6 months ago release 'hidden' bhp as the cat is restrictive, quicker spool up of the turbo.
Power increase depends on the car.
