Welcome to Just Commodores, a site specifically designed for all people who share the same passion as yourself.
Oh deer lord tin snips mind fielding this one?
Just went fishing through the Ford forums to see what they are preaching about on cat backs for their sixes. They are all fawning over XForce Cat Backs yet our knowledgable bretheren have been suggesting otherwise. Guess it goes to prove that you either trust the person giving you the information or you go to a bloody exhaust shop, listen to what they are putting on their cars and work it out for yourself. Me, I took snips advice, looked up the local suppliers asked them what the had on their cars, went and had a listen and chose KPM. Can I recommend you do the same and then share the decision with this forum so the next guy can learn by your efforts.
