Another Exhaust Question
I know there are plenty of Exhaust questions on this forum, but I haven't found an answer to my question. I am going to put a Flowmaster Force II CAT-Back system on my car. What I haven't decided on yet is if I should use the recommend kit for the 3.8L which as a reverse 'Y' pipe bolt-on or get the GT kit and make a custom 'H' pipe so it is a true dual pipe. Skill wise I am fine either way, what I am concerned about is if I make an 'H' pipe, will I loose all my back presssure and therefore loose my low end torque? The recommend kit uses 2.25" pipe and the GT kit uses 2.5" pipe.
