stock 68 383 rr with 2.5" X pipe, dynomax super hemi turbos through the hp exh manifolds. it was somewhat quiet but had a bad resonance between 2 and 4K, 35 to 45 mph, i had to add resonators just before the tips like the hemi RR had, they are magnaflos 22" or so long, very quiet now, when i open it up it sounds like the blues mobile jumping over the opening bridge!!
