    so a 3" exhaust on a blown 3800 does nothing but increase volume and potentially LOSE power.
    i gained 3whp when i switched to my 3'' cat back...

    I literally have the same setup you do except my muffs are Borla and my headers are zzp... only time my exhaust sounds bad is above 5k rpm ill vouch for this setup sounding as good as you can get our cars to sound though!!!

    What happens to exhaust gases as they cool down? As exhaust gases cool, they slow down. Think about what happens when the you are running and exhale slower. Takes you longer to catch your breath. Right?

    Where in the exhaust system do the gases cool down and is it farther down the system as you increase rpm? Gases begin to cool almost immediately. Not by a significant amount and yes, it is always further down the exhaust system that they cool the most. A larger exhaust system (more surface area) will cool the gases more quickly.

    Where is the pulse based exhaust scavenging concentrated at? The scavenging depends on the entire exhaust system (pipe diameter and length, header design, muffler design, back pressure, etc.).


    there are several 500 +wheel HP cars with 2.5" exhaust sytems driving around
    Z06,camaros,rustangs,T/As,Evos etc etc....
    evo? the rest i can believe but not an evo.

    Started a photobucket account for all you 'nay sayers' lol. Go to their website. Its listed as a public account. Search under KEVINDLITTLE. This should get you the pics and vids. Pardon the green on the car, its yet to be painted since i killed the deer. Paint will be at the end of the month. All blacked out. Going to be on vacation for a few days so if I dont respond, just give me a few. And no I wasnt

    First one's his vid, click it to play. I actually agree with him, sounds better than most exhausts I've heard on these cars!

    ^IMO Loose the Thrush decal, and route your rear plug wires UNDER your supercharger snout. Other than that, clean engine bay.
