i had the complete atr 2 and a half stock apearing exhaust with pit bull mufflers on my 87 GN!! believe it or not the car ran better through the full atr exhaust than it did running just the open 3 inch down pipe! very quite also !!! if atr were still open i would put thier exhaust on my 98 transam no doubt!! they used to be out of south carolina but i heard they went ouit of business its to bad they made very nice perf. products!!!
