    i put cat's in the y-pipe for smog reasons, and that helped quiet it down a lot. then i went and bought a hooker aero chamber muffler and took it to a muffler shop and had them weld in the muffler.

    i don't know why people pay 300 bucks for another cat-back when you can buy a muffler for 90 bucks and pay an exhaust shop to weld it in. the only mod they had to do was make a new intermediate pipe and cut the 2 outlet pipes to the rear of the car and it's done. total cost was like 150 bucks for you actually save 150+ by not buying a new cat-back..

    never really did understand that one..having a LM exhaust is not an end all situation where you have to ditch it, just have to modify it!

    just my .02
    yea but having the LM in tact, you can sell it for about 200 when you get another catback

    Which exact Aerochamber muffler did you buy?

    I came here searching for this exact information. I have an '01 SS, long tube headers, loudmouth, and I hate the raspy sound. I want the rumble like I used to get from my old '68 GTO!

    I think part of the reason for the big sound difference is the single exhaust system has to move twice the volume of gas that a dual would, so the velocity is higher, and there's a lot more high frequency noise. It'll never sound like true dual when it's single. But still, I don't like it sounding like a V8 version of a rice fart pipe.

    Hope this thread isn't too old, thanks for any information you can give me.
