If i get a custom exhaust which is cheaper by at least 200 bucks for just getting a muffler and getting bigger piping 2 1/2, will it provide the same performance as a greddy or so?

 

...bigger piping does not = HP in Exaust terms.

2.5 inches is good (Do it.)

The real key is to have MANDREL BENDS!
No crimping in the exaust bends, when they build it.

You want to keep the exaust flow as SMOOTH as possible.

If you plan to get a YPipe (DO it.) make sure you keep your stock muffler.
