Thanks for the help everyone. I knew it sounded fishy, but since I don't know much yet, I thought I would ask...
I like the idea of everyone called 4wp... of course, it could have just been the guy was misinformed... It was one of those "well my buddy said"... type things.
Anyway, thinks for clearing things up. I'm ordering my new 4" MBRP 409 SS Turbo back with Cat Delete before the end of the week!
