Exhaust Size Question

[LxiMax]

Would running a 2.25" mandrel catback on a GST running 15psi on the T-25 be too much of a restriction? Or would it just be a better idea to go with 2.5"? Not looking to make tons of power, just a little more then factory since it's a DD.

You may want to search a bit. This seems to be a well covered topic.

Bigger isnt always better. Too big and you'll not have enough backpressure.
