Exhaust Noise Problem
Discussion
got two Supertrapp's sound like they are the ideal solution for loud american cars.
"SuperTrapp is the only U.S.D.A. Forest Service Approved spark arrestor without restrictive swirl baffles or fragile screens.
The exhaust outlet is formed by stacking the individual diffuser discs to form a series of annular openings. The precise spacing between the discs provides a barrier against noise and sparks without restricting the exhaust flow. The number of diffuser discs required is proportional to engine size. The exhaust noise will be minimized when the least number of discs is used.
As the exhaust flows out radially between the discs, the noise is first dissipated and then diffused over a quiet 360° pattern. After leaving the discs, the exhaust path curves inward toward the centerline and is rapidly cooled by mixing with the surrounding air. Only 1⁄2" side clearance is required between the disc’s outer edge and any heat sensitive areas."

I use these:

This don't go in the tips.
They are a more permanent solution, and are placed in the pipe upstream from your mufflers. Probably an hour of labor at any good exhaust shop.
They don't restrict exhaust flow to any significant extent, and before and after dyno testing on my car revealed no loss of power or torque. Sound reduction was quite good. Brought my overall sound levels down from truly obnoxious to reasonable.
