So this is the big overview.

You are getting rid of the old second muffler, so you can pull of some of the crap that is normally located behind the fuel tank to accomodate the second muffler (resonator). This shot does a good job showing how clean you get get the area behind the tank by dumping that stuff - there is no cosmetic difference from the rear on my car.

I opted to go with a 2.5" exhaust system, something of a balance between economy and performance. For purposes of this NA application 2.5 should be fine, if I were looking at a higher performance turbo app I would probably move toward a 3" system, however there are some additional costs associated with that diameter pipe including matterial, and overall management of getting a 3" system to fit properly. Strictly a personal choice.

*Note - the need to have some element of 'back pressure' is a wives tale when it comes to performance exhausts. When someone starts telling you about the need to incorporate a degree of back pressure in your performance exhaust it is usually a good indication that they don't have much of a clue. Back pressure is the very thing you are trying to eliminate when you are going through the hassle of installing a performance exhaust, so don't worry about it.

Matterial wise, I chose to go with the galvanized pipe rather than stainless. Much more cost effective, that pipe should hold up fine for many years, and if parts need to be replaced it should be able to be done inexpensively. A good stainless set-up is very costly, and IMO needs to have a great deal of investment in the vehicle to justify the cost. I have had this system on for nearly 10 years with no deterioration of the pipe to date.

Cat is a "Car Sound High Flow Cat" and muffler is a "Dynomax Ultra Flow SS", 18" dia I think on the muffler, straight through on both. Each should be pretty easy to find on the web for under $100. Dynomax has a great tone, none of the 'fart pipe' characterisics. A good deep note but tolerable when you are off the throttle.

Finally, the best exhaust is going to be the one that requires the gasses to make the least number of turns on the way down the pipe. I opted to go with a 'straight shot' out the back as shown in the photo - no need for expensive mandrel bends if the pipe is straight. This entire run has no substantial bends from the header to the outlet. And the stainless tip peeping out under the right rear bumper looks very sharp - highly recommend this routing!

Overall, a great bang for the buck, you will notice the performance gains the first time you step on the pedal.
