Nope, no difference in flow, as long as the exhaust shop utilizes mandrel bends.

Slight difference in durability exists. For example, Apex-i puts a rust-resistant coating on their exhaust piping. Stainless steel still rusts, it's just more rust-resistant than plain steel. To solve this problem, you can coat your exhaust piping in some high-temp paint. But, seeing as you are in L.A., you shouldn't have much of a problem with rust.

Muffler shop piping will also fit better (as long as the shop does quality work), because it is custom tailored to suit your needs.

2.25" diameter will be enough for how much output your engine has.



P.S. you only have one header.
