as stated above, it might be cheaper to buy the muffler and have a shop fab up the exhaust for you.
the full s/s borlas can get pricey, i bought a s/s universal muffler and my friend's shop fabbed up the piping from the cat back (wasn't mandrel bent, but saved quite a bit of $$$ going with crush-bent).
works decently well, noticed an increase in mpg, and best part is i spent around $200 and a case of soda for his installers for a full cat back. they even tucked the muffler up nice and high so it wouldn't get crushed on rocks in case my wife ever decided to tackle something tough.
