Will changing the exhaust system to a mazdaspeed muffler make any difference?
ur question doesnt really make any sense but exhaust systems do improve performance a little bit because they reduce the back pressure from the engine by having a high-flow cat converter, larger diameter piping, and a less restricting muffler, u can improve exhaust flow, which takes the pressure off from the engine, giving u an increase of 5-10hp depending on how bad ur exhaust system was and how good ur new exhaust is but the key components are the headers (piping coming straight from the engine) and the high flow cat.the muffler makes an insignificant difference
Unless you are prepared to invest between $500 to $800 minimum to redo the air intake, headers, catalytic converter, pipes and muffler as an entire system.you are just throwing your money away. One piece will do VERY little for you unless you just want the look or the sound. Save your money.
