The new exhaust is done, and...

The tapping noise I mentioned? Well...
...it turns out that the metallic tapping noise I described hearing at WOT was actually caused by exhaust leaks, at the same location (between 1 and 2 feet before the x-pipe) and on both sides.
When doing this project, we decided to weld everything except at 4 locations, in order to be able to drop the portion of exhaust piping that is under the transmission (in case work had to be done there at some point).
The front two points is where the leaks were. The loud tapping I described was actually high-velocity air pulsing against the heat-shielding material. As a temporary fix, I had the kind Meineke folks further tighten the clamps (sleeves) already in place at those locations. The leak on the right side is now nonexistent, the other is still leaking slightly. Welding will be done this weekend; I figure that my worries about needing to access the transmission are unjustified at this point, considering the car still does not even have 20k miles yet.
This next piece is the part that is most important for those considering exhaust mods similar to this one: After almost eliminating these leaks, the exhaust note changed in such a way that...well..the thing sounds absolutely incredible (almost melodic) when not leaking, and the interior is amazingly quiet--even with the resonator deleted. Any concern I was having about excessive noise or drone is entirely gone. Y'all need to get up on this mod if you were previously undecided.

...NO problem, here are some sample pics of my Hi Flow cats I got on, and hopefully this week I'm getting my Magnaflow exhaust and tips put on also.

**Just make sure you have the correct size inlet and outlet for the CATs. I stayed all the way with the stock pipping size at 2.25" not 2.5". If you want the 2.5" just contact wholesalemagnaflow.com for the right part#.
Cheers!
