Factory cat equipped (same as factory decat) - 196.5 BHP @ 6500rpm & 184.2 ft-lbs of torque
Cat delete bypass tube - 197.7 BHP @ 6500rpm & 180.1 ft-lbs of torque
Cat delete custom resonator - 199.9 BHP @ 5500rpm & 199.2 ft-lbs of torque

The interesting thing is the differences in performance.

Cat delete bypass tube - +1.7bhp -4 ft-lbs of torque (yes MINUS 4 ft-lbs of torque!)
Cat delete custom resonator - +3.9bhp +15ft-lbs of torque

I found this on a previous post on 944 site. which had an explanation why this occurs.

In synopsis look at the results, has any one made a hook up like this replaced the CAT with a resonator? Like to hear what to have to say ,
thanks again
