Question regarding the J's racing 70RR, so this exhuast will bolt up to the J's CL7 header and thus eliminate the cat and the piping is from the header all the way back correct. If this is the case other than being illegal performance is what you would expect no restriction, as straight through as it can be and with the ECU reflash you can expect power throughout the rev range. I am seeing atleast 20+whp there. With the 70mm piping of the J's if you plan for future upgrade like say cams, S/C, etcc.. this exhaust would be best suited for.

You can always buy a highflow cat (or use your existing one) and get the exhaust shop to weld the compatible flanges (and piping if required) to match the length and angle of the J's racing test pipe.

Good to know. That's kind of suck when you basically need J's Racing testpipe to fit the header
