Jim's right, for all of us to see the true potential of these cars, the exhaust has to be "uncorked" carefully!!

PHP(Pauls High perf.)Dynoed an 03 Cobra without a catback and got 25rwhp i believe.I dynoed a Mac catbach and got 18.8 rwhp.
You might do h pipe and keep stock catback and get similar numbers.If you do catback and get 18..If another guy does x pipe only, and gets 18,,That does not mean both will get you 36..
it does not work that way.
On my KB Cobra after adding 3in X pipe and Magnaflow catback without dynoing...I added Long tubes and dynoed and only got 8rwhp from the Long tubes.
If i did the Long tubes first i might have got 20 from that mod.
