I need dyno proof on which is the best muffler/catback.. I would like to get some real life examples of dyno proof on which is the best muffler/catback. I am talking about cutout type of results..

No cutout here (I'm sure more hp is obtainable.)
True duals make the flattest powerband in the higher rpm's of any exhaust.
The car just keeps pulling at WOT.
My car makes consistant power all the way to about 6300 RPM's ON A STOCK CAM/HEADS <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />
You can't say that about most setups.
Here is a dyno graph of my car before I added a Shaner Stg. II throttle body. The throttle body gave me 8rwhp/8rwtq on top of this dyno graph.
Just bolt ons for a few days more <img border="0" alt="[devil]" title="" src="graemlins/gr_devil.gif" />

You won't find a flatter hi rpm power curve.

Re: I need dyno proof on which is the best muffler/catback.. While I agree that true duals are the way to go, assuming you dont have a ton of money to throw around (true duals aint cheap) I've heard the SLP loudmouth is probably the best, since there is pretty much no resistance whatsoever. Keep in mind though, it is called the LOUDMOUTH. Its volume is borderline obnoxious, but to each his own. Good luck on your decision.
