same here

I have the Magnaflow 2-1/2" system on my '68 Mustang. Am disappointed how loud it is. Also, the right and left side pipes that exit the mufflers are not symetrical. The passenger side fits perfect. But no matter how I try, the drive side bears against the shock. My car does not have staggered shocks. Is the poor fit a compromise to also fit staggered shock cars?
I'm considering the OEM style resinators before the exhaust tips.
