ok, i was going to open my exhaust to custom 2-1/4 inch exhaust which is slightly more open than stock, go with a high flow cat, and delete my resonator all together. am i going to lag in the lower rpm's and gain in the upper? will i lose torque, cause thats not what i want. thanks alot. btw, the guy i know doing all the work wants 350 for the custom piping, high flow cat, and installation. this a good deal?
