I've been looking, but I can't find much of anything. I've finally decided that my exhaust is WAY too loud...it's bad when you follow your friend through downtown and on the interstate and he hears your car echoing off of the walls over his WRX's Catback. Right now, I have: Borla Singleport Header, Custom 2.25" Headerback, High flow cat, Ractive Carbon Fiber muffler. It's loud... http://www.putfile.com/media.php?n=Untitled2118 <---Sound Clip

Does anyone know of a performance muffler that is a bit quieter? A universal is ideal, and I'd like something that doesn't look like a fart can.

I've been thinking about Edelbrock's SDT Mufflers... EDL-55741 is the Summit Racing Part Number for the 2.25" center inlet/2.25" center outlet Model. They're meant for V8s, so I'm not sure if there would be any ill effects to putting it on my little EJ22 (such as lack of flow).

You uncorked it, and now you're too drunk?

Ah, well.. If you had a quiet muffler and I had a feather in my ass, well then we'd both be tickled, huh?

I would say look for a larger muffler. Lower exhuast tones tend to resonate more inside the baffles of the muffler, as opposed to your 'fart-can' style, which is just basically straight-through. I would check into some dual-tips, or something that's a bigger muffler, in general. I have one from here:

That's the catalog page, I have part# 1009, dual-tip with the up-curve. Any of the other ones are quite attractive, as well, and they all produce lower, more mellow tones, and provide very good flow.

I've been doing a lot of searching a reading on Google and came across some good information on a honda forum (please forgive me :P ). Straight through mufflers (Resonated or Baffled...like my can there) seem to give the better high end gains and can actually cause low end torque loss in N/A Engines due to lack of back pressure. On the other hand, they are very well suited for Turbo applications where the faster flowing gases will make for quicker turbo spooling. Chambered mufflers, like the Edelbrock SDT I was looking at, tend to maintain a bit of backpressure, keeping the low end torque gains a lot higher, but making high end power gains minimal. Chambered mufflers tend to apparently be a lot quieter on average anyways. I'll look at the site you posted though.

:smt017 I was wondering the same thing...it doesn't look like it'd even fit anywhere under my BD Sedan...

i mentioned on another post that i liked the sound of my wife's WRX with the Flowmaster cat back, and i'm going to put a 50's series 4" on my 95 Legacy. i think thats the quieter muffler than a 4's series muffler.

The exhaust pipe bend looks to be a subaru style though. Very interesting. 2DL, get back and answer the questions!
