3rd, has anyone dynoed their car before and after to see the gains? Thanks guys!

Alot louder......check my sound.....I have no mufflers, no cats...
the first one is on the dyno and the second one is before I had my car tuned. Yes you can run cats. You can buy any cats you want and have them welded in or buy catted mid pipes. I will be buying catted mid pipes before my next inspection. There is a off road pipe that comes with them to connect to stock or any aftermarket exhaust until you get cats. I ran a dyno run before tune and after tune but not stock...sorry I just couldn't spend the 300 bucks to get a base line dyno run...However I can tell you the average dyno for LS3 is around 370 ish......I ended up with 400 RWHP before tune and 413 RWHP after tune......
