That camera is not reproducing the sound very well, it's using a compressor to limit the sound peaks. The actual waveform should have more low end and more amplitude.

I ran a 10 series on a 5" tip. Loud as hell, but too much bass pulse with my cam. When the cam chops, the pulse will chop right through nearby buildings...

Jeez John, that thing is loud. What are the specs on that edelbrock muffler?

Just bought a 24" magnaflow to replace my 15" mbrp. If its not reasonably quiet I'm going to just chalk it up to the 4" and roll with it.

So you're saying the sound isn't even close to that growl?

Suburbazine

Yes. It's basically a single baffle muffler, one step short of straight pipes.

If you noticed when he was pulling onto the street, you could hear the tires crunching over the exhaust. That muffler is nowhere near that quiet at idle or off idle...the only reason it sounded like it had a growl was because he has a stock cam in there. It's loud, but only the only difference over a 40 series is the 10 series passes a little more low range and a lot more high range. (aka NOISE)

Well then I need to get my hands on a Borla ATAK muffler and modify or try finding a Corsa Sport db somewhere. I didn't think it would be this difficult to replicate a sound.

LOl, yeh it is loud at idle, driving isn't too bad. Uhh case size is about 27'' x 9''

Both of those will sound like crap behind a truck engine and truck headers. If you can find one give it a shot and let us know how it turned out.

The Borla and Corsa mufflers use tuned box sound cancelling to limit the sound level while keeping that signature note...on specifically measured and matched vehicles. For instance, take a 2010 Camaro with Corsa mufflers. Add longtubes. Now, the car sounds normal from 0-2200RPM, but when you get on it the muffler puts out a loud raspy noise like a blown speaker being overdriven.

If you are looking for something similar in design to the ATAK I'd recommend looking at Goerlich Xlerator mufflers. They're not tuned to specific vehicles and are a whole lot easier to find.

Never even heard of them, but I'll definitely check them out!

If you can find any good clips of what they sound like on a 5.3 let me know, I'm having trouble finding any.
