              yep, for sure!

              will probably add 5psi to the base of ~40 psi, i currently have OBD1 340cc H22A injectors in...

              i was runing ~70psi base pressure with the 240cc B16A injectors prior...

              +5psi should be good for another 15hp at fly without increasing MAX duty cycle

                  The question was is there a noticable difference. I'm not sure, especially if you're running a standard exhaust manifold, because I think the benefits of a catback would be maximised more by having a good manifold than the other way round. I guess it depends how sensitive your butt dyno is; I'm not sure mine could detect such an increase - though I'm sure there are of course those amongst us who can notice and utilise the increase.

                    yeah you can feel the difference. For me in terms of response, engine revving out smoother, and top end power was awsome!

                        i think there is a noticeable difference. yes the outright gain in power is not that huge, but no one mod on a n/a b18c / k20a is going to make a HUGE difference without other ancilliaries being looked at as well. int his sense it is unlike many turbo cars where a simple cat-back and filter change may net quite large improvements in power and torque eg.r33 gts25t or s14/s15.

                            yeah comparing products... I had a Buddyclub B-pipe on, which I swapped for a Spoon one. And the difference was good... wouldn't say amazing, but definately noticable.
