hi, just got a new exhourst system on my VP S2, 2.5" catback 'ultraflow' straight through muffler, with a supadog res...im not sure if i can notice a differnce in performance yet, but its bloody loud! im looking at what next would be the best thing to do, i want to improve take off... would extractors, CAI, ecu chip be best?

westy that exhaust that you have just put on wouldnt give you really much at all,you probably wont be able to notice it and i would suggest that it may have knocked a tenth of a second at most off your qharter mile times,probably at best 1 to 2 kw,s,put a set of extractors on,descent air filter system and a cai and thats about as cheep a performance boost that you will get ,after that it gets more expensive but if you really want to FEEL the extra performance then it will cost you big dollars
cheers

change your diff ratio. changing to 3.7 or 3.9 lsd or locked will give you heaps better take off!

hmm how would it have made my car slower? seems like a good flowing exhaust system to me?
from what ive read CAI and filter system is an easy and cheap mod will there be a good boost from these?
