I'm not big on flowmaster anymore. Good sound? definately, but anyone i've had have rusted out at the pipe connections. My previous car, a 98' acura integra, had a flowmaster and it sounded AWESOME. everyone thought i did an modified engine swap or did A LOT of work the engine. lol, so yea i guess i'm leaning towards the Magnaflow SS cat-back. . . anyone ever hear one on a 4cyl tacoma?
