HKS on Sedan with DROOOONE
#18
I just installed my HKS and the drone is HORRID between 1,800 and 2,400 RPM - cruising around town in the 25-40mph range is driving me batty - I did not install a gasket between the midipipe and the HKS - could this be my problem??? any other suggestions would be appreciated - if I can't get this fixed the stock unit will be going back on this weekend.
