Um, not true......
I did true dual 2" pipes all the way back (to what resembled mufflers with a
pipe straight through them) on my '94 and it had NO TORQUE, was the worst
running SHO I have ever had the misfortune of driving. I took it the next
day and had the stock system pieced back together and re-installed.
What a great way to waste almost $700.
