Looking for some friendly advice! I have bought a 52 plate WRX with PPP and am thinking of getting rid of one of the CATs. i still want it to pass the emissions test so which exhaust upgrade is best for my needs? saw a Ninja front pipe with sports CAT but thought id check with you guys first.

cheers
Jim

 

You can get rid of your up pipe cat and replace your down pipe cat with a sports cat, like the Ninja and you will still pass the emissions test. As you have PPP I think your centre cat will already have been removed.

 

ok thanks for that mate
