A Loudmouth sounds great with Mids....
Get rid of Flowmaster, Get a Moroso Intake and Trick Flow elbow, and you should see another 15-20hp.

So what was like watching your car on the dyno? I've never got to see a dyno run in person yet.

Hey 94camaroZ28SS, I ran my 96 on the dyno before and after I did away with the so-called ram-air and my stock exhaust. I put in the K&N cold air intake, pacesetter ceramic coated LT headers, and the TSP X-pipe exhaust.

The before run put me at 274hp/306tq and 12.5a/f

The after run was 282hp/319tq and looks like around 11.5a/f (needed tune badly).

I'm guessing it would have run better if it that A/F was closer to 13. I could feel a little difference in throttle response going from the stock SS intake to the K&N. Although, getting the filter on it from the access panel was a pain now. Hope this helps ya out.
