Welcome to Just Commodores, a site specifically designed for all people who share the same passion as yourself.
put me down for a set if you could get your bank details to me via pm or something? and how much extra for postage, does this come with everything i need to just take old ones off and replace them apart from the value springs of course? should i pay first then wait for mailing very keen to get these in the car asap lol thanks steve
ive installed these today, which was a straightforward job
buick engine seems sweeter, more willing to rev
still need to get cat back exhaust currently got extractors 2.5 sports cat, but 2 1\4 whisper quiet system
also got cai and memcal (do memcals actually work?) i noticed no difference
also a lpg vehicle (suck through type, very restrictive diameter intake) i took this off and noticed a big performance difference on petrol
im hoping for a bit more from the exhaust still
overall i think its a very well engineered product and is worth doing at that price for surehowever with any motor performance upgrade its all about the sum of its parts, no one thing gives massive gains, everything has to be done to work together (synergy?)
im curious to hear about other peoples results from the rockers
