Hey guys. This is my first post. I traded in my '06 Civic Si and bought an '11 Toyota Tacoma SR5 V6 4X4 this recently past monday. I have to say I love it so far.
Now I'm already looking to build my own custom exhaust. I was wondering what size piping is best for the 4.0 to exhale through without hurting my low end torque. I want a nice sound but more importantly some better performance. I plan on constructing my exhaust from the cat on back using mandrel bends and plan on doing 1 in and 1 out. Keep in mind I do plan on adding some other mods in the future (intake, headers, and maybe a chip or piggy back) so i want the exhaust to compliment my future modifications. Any help would be appreciated.
