Thanks for the replies guys, awesome to get help from the forum. I figured I would do some welding. I cut the aftermarket pipes exactly to the size of the old pipes, I used the pipes that go to the engine and welded the aftermarket pipe to the tt cats, from there I bolted on the new mufflers. The only stock piece left on the whole system is a little bit of pipe that swoops up toward the exhaust manifold. I cheaped out big time, not the best idea but I got'er done. Thanks guys for the help again!
