[WARP TEN]

A good solution would be to get a Corsa exhaust, and if budget constrained, you might be able to find a used one. Marc Haibeck might have one, as might others on this forum. The resonance frequencies created by the LT5 and many other engines occurs primarily at two rpm points, about 1800 and about 3400, and they manifest themselves most noticeably under light throttle application. The Corsa system (like the stock system) utilizes Helmholtz resonators to tame them both. There is one in the center resonator that deals with one of the rpm points and there are Helmholtz resonators in each of the rear mufflers to tame the other. (I forget which handles which frequency). In the early days the Corsa was the only one to really quiet resonance other than the stock system. Today I believe there are other systems that do a fairly good job of it but not sure which. Others on the forum will undoubtedly chime in. Good luck with it. But I think getting a different exhaust system than the one you have is probably the most straightforward approach. --Bob
