I have been reading up on exausts and doing a lot of window shopping, and I'm probally going to go with a new exaust from the headers back. (No cheering from the peanuts' gallery Ash.)
From what I can gather and based on prices I have received and heard from others, it seems that the Pypes system is the most cost effective. Also, from the postitive replies from users of the system, it seems to create more power than custom exausts. It is a case of cashing in on sweat equity when you diy.
Pypes has a system with the transverse muffler, but if I recall, it's pretty high dollar. Based on what I have read, the claim is that the transverse muffler isn't that efficient. Whatever you decide keep in mind that H pipes or X pipes are major mandatory. Also you want to have the mufflers as far back as possible.
