the b and b resonator is most likely costing you 15-20 rwhp. i ran a b and b setup on my zr1 a while back as a comparison t0 my 23/4 in set up with 3 in super turbos and a ladder style crossover ..with my set up she ran 409.9 rwhp and 373.3 tq with the band and b with resonator she ran 390.6 and 368.2 tq. then installed a 3 in x pipe and she went 404.7 rwhp and 368.1 tq. all runs were done within 2 hrs of each other. we figured out that for my car that 3 in was just alittle too big for me with my present engine combo /.
