Default Looking for a quieter exhaust, suggestions?

Hey everyone,

I have Borla headers, random tec highflow cat and strommung cat back on my car for my exhaust setup, but its too loud for others, I got a ticket (138$) and I dont like having to creep around whenever I see a cop.

I love my strommung soo much, so it really sucks now that I might change exhausts. Here's want I want from my new exhaust or suggestions for making my strommung quieter.

The same (or better) performance as my strommung since i need as little restriction as possible with my new engine going in, i want the most out of it.
Preferably no large tips, i liked the strommung becuase it diddnt look obviously aftermatket.
Other than that thats it, I wouldnt mind pics or links if you have then when you post. But I dont want to loose any hp if possible.

Thanks for the time guys,

PS: What would you do in my position? Im also tempted to just risk the tickets because I love the sound i have now. Thanks again.

Personally, I don't think the Stromung is loud at all. It barely whimpers imo. But since you do have it coupled with the Borla header, that's probably your problem as to why its louder.

Any other type of muffler will still probably be loud due to the header, but you can try the Greddy Evo, or the Apex'i WS...but I'd just stick with what you have now. Or maybe an Apex'i N1 but stick in a silencer. Ooh I know, Apex'i (and others that copied it) has a cable operated flange in the exhaust stream that acts as a silencer. Full open you get regular flow, close it off a bit and its quieter.

They're harder to find than Fish Nuts, but I have a STi Ver6 muffler, and it flows really well, while maintaining a reasonable tone and volume - put a WTB in the classifieds. You may have to spend a bit more than average - I know I wouldn't sell mine for cheap (or at all), but I can't think of a better choice.

I was reccomended an STi or SPT exhaust for my car, does anyone know how it compares to strommung in terms of performance? If someone could also point me in the right direction to find a pic that would be great also. Thanks for the help guys!

prodrive WR sport...just find someone that's selling ones for the GDA's and have the hangers moved, so you don't pay through the nose for the elusive GC8 muffler...

it looks like a nice factory piece, sounds lovely, is about as quiet as you can get (it took putting on a set of headers before i could hear the thing inside the car), is FAR better constructed than any of the STi mufflers (except that lovely s202 titanium one of course), and flows nicely, since the piping is obviously sized to support a turbo...irvine subaru was selling them for $300, although i'm not sure if they still are.

also, it should mate right up to your stromung midpipe, since stromung doesn't use goofy proprietary flanges...

Get a Magnaflow muffler with a resonator in the midpipe. I dont think the stromung has a resonator, and I have heard DDman's car with the Magnaflow muffler + Borla headers and its amazingly quiet compaired to just a stromung catback. Its much cheaper too, and flows very well.

Keep the current setup and get a resonator in the mid-pipe. I think that is what I will be doing next week. I have the same setup and the random tech made it REALLY loud and after a year I am going to quiet it down a little.

I'm with Poppa Smurf. You should be able to have any muffler shop add a resonator to your mid-pipe for under $100, and that should quiet things down without really changing the tone and with no effect on the performance.

So, im leaning towards keeping my set up right now and resonating it, anyone have experience with this? I really dont want to hurt power or add restriction, but this sounds like the best route for me to take. The replies are great guys, keep em coming!

PS: I htink my cat is gone since I was running very right with my heads and cams, anyone have a cat go out on them? It souds liek the rattling is comming from the can outside the car, but inside it feels like its right under my feet, any tips?

Thanks a lot!
