Re: Any benefit of extractors on BA 6 N/A
i've got pacemaker extractors, and was quite pleased with the gain in throttle response gained. i couldn't really perceive any huge difference in power though but the car did feel a touch more torquey though.
i had the cat back on for a while before the extractors, the improvement in note was great. but no difference to performance whatsoever. the cat back was $520 from ford, it is a herrod 2.5 inch cat back and i fitted it myself (an easy job).
and the the extractors were also $520 fitted, i had this done at a shop because this required welding and moving the cat to accomodate them. ($80 labour included)
i'd leave the cat there, as there is no real benefit in replacing it and it's expensive. this is because it is quite new and won't be restricting the flow all that much like an older cat. however a high flow cat would be better but the difference you won't notice for the $300 extra or whatever.
i'd do the whole exhaust in one hit. but if you don't want to part with $1000 i'd go the the cat back for the improved note at first and get the extractors later. IMO.
once again, i'm happy to field questions.
