Here is the custom exhaust build.

Before: As you can see, she had a stock muffler the size of a tank. She also had a whole bunch of wasted piping.
During: We removed the stock tank muffler and piping. She not only had the huge muffler, but four catalytic convertors. We removed everything up to the headers. We ran dual piping and added a smaller Nissan muffler to each pipe right into two out of the four stock catylatic convertors all up front, and then straight duals back. Two catylatic convertors was plenty out of the four. The stock pipes ran from doubles into singles twice, than duals through a single chambered muffler. Yeah, alot of pipe and steel waste. We lightened the car alot with the removal of the stock muffler and piping. Running straight duals lessened the weight, made a much deeper sound, and added a small gain of power.
After: Here is the finished project. We also added sliced tips which look great on the car.
I reccomend to have an emissions computer when you do a project like this. Especially when removing equipment like catylatic convertors. If you live in an emissions regulated state like mine, you can get into a whole lot of trouble if you remove such equipment which causes a failure in emissions. But, it worked. Make sure to verify your car is legal before operating. You can get in alot of trouble and recieve alot in fines if it is not legal.
