I am looking to get a new exhaust but idk what sizes. Since i have a 2.4l should i stick with the 2.25 piping or if i go with 2.5, will i lose power/torque? I know that i am going to get a glass pack instead of the resonator but im unsure of the muffler right now. I want it to sound loud, but no rice. What length should the glasspack be? Any input would be greatly appreciated.
