Hey guys, new to the site, but I built a 70 duster 383 big block, the motor is stock except for a Holley 750 double pumper hooker headers with a 31/2 collector, it was rebuilt years ago and runs amazing, anyway, my whole exhaust from the header back is 31/2 and with dynomax race bullets it's incredibly loud, are the 31/2 hooker aero chambers any quieter? I have side pipes and want to dump the exhaust before the rear with turn downs, any thoughts?.. Thanks
