is it okay to straight pipe it with a stock filter set up?
Yes but you should spend the $50 to get a 6637 style intake also. Once you open up the intake and exhaust you will feel a bit more power and see your MPG's go up a bit.
I straight piped my exhaust and added a 6637 filter and gained 1.5 MPG.
