I just swapped my stock TRDP exhaust with a standard exhaust from a forum member here. No issues with the swap as long as you swap the full exhaust from the muffler back. As stated above, the standard exhaust flange bolts to the tail section using 2 bolts. And the TRDP exhaust bolts to tail section using 3 bolts.

took some pictures with both exhausts side by side before we reinstalled them. I'm sure he will post up the pictures after he wraps up his Thanksgiving festivities
