mettams are awesome for doing weldjobs etc, and they are real cheap for stock exuast system.
for my gtr ill be getting a N1, love the sound and they arnt 2 loud.
i bet the one from mettams will be hell loud.
i paid $700 for a 3inch mandrell cat back, with a stainless muffler a few year back for my turbo laser, and it was hell loud. got it done by formaz.
