Wow thas alot...I would say get an aftermarket bolt on and DIY. I ran my exhaust on my old 96 Civic Ex and It took about 1.5 hrs. The problem is ground clearance. Get some high ramps and a Chilton's for torque specs and hanging locations and all that jazz. May be costly if you dont already have tools and ramps but at least you can say "It's done right".

The reason I say to try it yourself is because I had a muffler shop run some Flowmasters on my Chevelle and 2 months later I was welding the welds back together. The dude working on my car was not very experienced but at the time I didnt have the tools or access to a welder. Also it was Friday and I needed it done then for the weekend.
