exhausts on I6
I have currently got a 2.5" mandrel bent with standard muffler and resonator and a high flow cat. My car is an auto and the exhaust note is not to my liking, it is too flat and it drones like all hell inside. Will changing the pipe to 2.25" but keeping the muffler, resonator and cat make any difference? Like a more defined note?
Also what change in power am I likely to see?
