These mufflers also come to the rescue of people who have long tube headers, no cats, and a wide open x or h pipe, and no resonators.. with that combination the stock mufflers sound like garbage and they also hiss like mad. the gt500's can handle the wide open race type exhaust system w/o going all cracky and crunchy (think popcorn in a tin can) and they dont hiss. Every other muffler that works is WAY to loud..
