VERY nice...just thought you could add justmagnaflow.com for misc. mufflers...maybe?

sticky any highflow cat info or how to gut the pre cats and ypipe mod.

Bassani hasn't totally discontinued the contour exhaust. While they don't make-to-stock them like they do for a mustang, they will make-to-order.

I ordered mine through www.performancepeddler.com (1-800-470-1443). I received it 3 weeks later.

Since I recently got an almost new Bosal kit, I thought I'd recommend updating that section. It's supposed to be a little loud with the other stock exhaust parts, but even then, some people opt'd for the muffler "silencer" inserts.

I have headers, optimized y-pipe, and high flow Trubendz cat pipe. When I put it on, it sounded like it was just straight pipes -- wicked loud! I got the inserts and it's alot more quiet, but it's still VERY loud, and has some small rasp ranges (3500-4000; 5500-6000). I'm now planning on replacing the cat pipe with a custom pipe... using the largest muffler I can fit in that area. Though, as much as I want to make it more quiet/sane, currently 6000-7000rpm sounds very sweet.

Seriously. if you want a good sounding system, Just go Trubendz Resonated Magnaflow or Borla. Just make sure you can get it welded or fixed, because their fitment sucks arse.
