is their any cheap way that i can straight pipe my car by myself or would it be better to just take it to the shop.

I have never done a welding job, but If you have acess to a welder it could be done cheaper than a exaust shop would. If not just don't tell them its a cat replacment pipe.

Just find the length of the cat, get some flanges that match and have them weld a pipe to the flanges. Get some gaskets and its a bolt in affair. Then when inspections come around, just swap em back!

I am doing this during X-Mas break! I checked at a muffler shop where I am in cool w/ the owner (I bought my 7 from him!!) He said no self-respecting shop would do a job like this b/c it is real illegal. However, he would do it if I drove in w/ the cat and left w/ it in place. Just tell the shop that is how you want it done and that it is for SCCA Auto-cross or some other lie. Good luck!

Mine will be free, thank you!
It helps when the car was bought from the owner! They are gonna install my Apex N1 for me as well!
