Description: 05-10 Jeep Grand Cherokee 5.7L Hemi Exhaust System by Magnaflow PN 16631. This system features T304 stainless steel with single exit and polished tip. Includes resonator and muffler for clean sound and minimal restriction for optimum power and perfomance. Its quieter than stock with the cutouts closed and much much louder when open. Expensive but I think its the best sounding exhaust for the 6.2 and probably would sound great on the 5.7 also. Reply. More posts you may like. 6123U.
