I saw Exhaust Depot's true dual dumped exhaust with the crossover pipe and Flowmaster 40's in a previous post. I don't quite want that much noise. I was thinking of going with a similar set up using Magnaflow di/do muffler (pt # 14398 or 14468). I think this muffler serves as a crossover pipe and muffler. Does anyone know? Also will this kill my lowend torque?
