Im curious. I want to mod my exhaust i just dont want the headaches of trying to pass emission checks in Vegas with long tubes . Right now my exhaust is stock with Flowmaster force II axelbacks
Shorty headers don't flow much better than the stock C5 Z06 exhaust manifolds. I believe the LS7 setup would be quite a bit better than shorties.

Shorty headers show about a 10RWHP/RWTQ gain and bold in stock location with stock cat. easier to install but gains are smaller.
