    N/A 2.25" FI 2.5" straight through muffler. Will be loud but will make power. Use the search function, theres enough stuff about the exhaust on our cars in this forum to keep you reading for hours.

    stock piping runs 2.25" from the exhaust manifold through the catalytic converter through the resonator. After the resonator, it tapers down to 1.75" all the way to the end of the muffler.

    I enlarged my exhaust from the resonator back. The first half of piping was 2.25" and then the second half of piping I took it up to 2.5" and it hooked up to an HKS Carbon-Ti Muffler with a 3" inlet and gigantic @$$ tip. I have a TRD CAI also, and the dynojet at modacar in livermore, ca shows 128 wheel horse power.
