Anyone dyno'd car with catback taken off to see possible results of catback exhaust??

I was going to dyno test this when I get off-road pipes on to see how much to expect from borla stinger.
I did this on several other cars and it was always dead on the same as the good aftermarket bolt-on catback I would then install.

There was a couple of threads way back when the Z debuted. Gains were almost nonexistant.....and that was on an 01!, with the freer flowing 02 exhaust, I wouldn't even bother......

The Stingers sound good however

Thanks, that's what I thought but the 9.5 rwhp quoted sounded to good to pass on but I thought that seemed unrealistic to expect. Most I ever saw from a ctaback on any car is 7rwhp and you figure our's flows well to begin with.
