i think this may have been a pre-mature post it looks like (from doing a little reaserch) the s trim and sq trim are really a sq s-trim sq standing for super quiet
lol how much do u think a kit sor the sq should go for used i offered a guy $1100 its a used kit idk how many miles but ill find out b4 i buy it if i buy it but its a complete kit for a 99/01 cobra i figure i can use some of the parts i need from that kit to put it on my 96 cobra and what ever else i need ill get from superchargersonline.com what do yall think?
my sq was loud at idle, but you really couldnt hear it once i got moving. idk maybe my exhaust was too loud (lm2, o/r H). but at idle its got a very very noticeable whistle.
but like stated above identical to the s trim as far as performance goes
