just an up date weather was great with the da being about 1900 . i had changed the muffler on my 3 in system from 21/2in inlet super turbos to 3 in . heres the findings from starting with the corsa to what is now corsa exhaust 12.75 @114.77 3 in exhaust with 21/2in super turbo mufflers 12.54 @115.77 3 in with 3 in super turbo mufflers 12.23 @116.40 the set up i have now is quieter than the corsa and seems to make more power too. anyone wanting a used corsa exhaust pm me with an offer
