Exhaust Questions?

[Hlindeen]

Currently ive got the old cast iron exhaust manifolds a set of 2 inch exhaust true duals, 18'' glass packs, with mandrel bent exhaust.

Ive been looking to upgrade to a different set of pipes this summer but not sure what to get, im thinking 2.5'' exhaust tubing but would 3'' be too much?

Im not for sure mufflers though, does anybody run flowmaster super 10's, or spintech prostreet mufflers?

And im wondering about getting a set of exhaust tips the angle cut ones but not sure if i should have the exhaust exit straight out below the bumper out the back or have them angle out behing the rear tire, let me know what you guys think Thanks
