Cut out worth it?
YES cutouts are worth it.
A member on here picked up 2mph in the 1/4 just by adding an E cutout to his completely stock exhaust (headers, y pipe, catback)
Do some research someone dropped there flowmaster muffler and picked up like 40whp lol those things are restrictive.
Edit: Heres some proof as too how restrictive a flowmaster can be

This coming Wednesday I'm putting on a 3 inch DMH electric w/ a new Texas Speed Stainless ORY on the Bird. I will post up the dyno results once I get some #'s.
Here is a sound clip on the LT1 http://www.streetfire.net/video/adva...-cu_694817.htm








maybe I was just expecting so much more then or didnt seem to be much faster when riding in it. plus, 155,000 on whole car didnt help
