Well the test drive went well- the power curve is different.. a lot more from 3500rpm and up to redline. It has a great sound but there is an annoying vibration sound that seems to be coming from the tip. Gonna put the bigger resonator back in - the one that says Daewoo on it.
Edit- so the vibration sound is gone im told it has something to do with back pressure.. Anyways with the one resonator and the delta 40 with inlet and outlet on opposite sides the whole thing mounts up well.
The butt dyno can definitely feel it through the rpm range.. Ive yet to open it up i got plugs and wires to do to fix a hesitation .. So after next tuesday ill post a sound clip and pic.
