I've got an '09 4.7 GTS (auto, twin pipe) and I suspected the exhaust valves were not working because I noticed no difference in exhaust noise in sport mode above 3000 rpm. Long story short, I had both tailpipes off, lubed, heated, hit, and now they're nice and freely moving back and forth. Gave it a drive down the street and got a lovely deep note over 3000 rpm, with a gurgling when coming off the accelerator that unfortunately stops when you drop below 3000rpm.
Short of buying an MC shift, is there anyway to get that noise all the time (not just over 3000 rpm) but in sport mode only (i.e not jamming screws in the ends of the vac pipes)?
