After owning the car for 14 years I finally found the "Perfect" exhaust setup.
I always wanted free flow exhaust, with rumbling sound at idle, and a nice scream when gowing WOT, but I didn't want the loud booming sound when cruising.
After years of trial and error, I have found a combination that does the trick.
I replaced the headers with repro HiPo manifolds.
I installed a H-pipe.
I installed two Dynomax VT mufflers (the ones that opens and closes).
I put two resonators behind the mufflers.
At cruising we measured 72 db inside the car.
My friend did the same with his stroked 289 and is also very pleased.
I just wanted to share this for those who seek the same solution.
