Full 3" w/ no muffler???

My Legacy came with an ebay muffler just welded on the end of the stock exhaust section. I've already got a 3in downpipe off a Wrx to put on, and when I do I'm going to go ahead and run full 3" all the way back. I hate the way most mufflers look, so was thinking about not even running one. I'd imagine to would be hard to make the Boxer motor sound bad, but what do you guys think about it??? Thanks

It will be loud and illegal.

Lol, never stopped me before. However this is different than my turbo Civic running open downpipe. Do the ebay mufflers really quiet it down that much???

I couldn't tell you. The turbo muffles things somewhat, however you will still need a muffler. I've got a straight through muffler and a resonator, and the sound is very good. Loud enough, but not obnoxious.

For a while, I had 3" straight through and only a muffler. Got lots of looks coming from a wagon. After a few months, the noise just got to be too annoying. Couldn't really carry on a conversation with the passengers. Long highway trips the noise would get on my nerves.

Got a resonator installed which helped to quiet it down and take away some of the raspyness. All is satisfactory now.

I have a 3" setup with a Flowmaster muffler AND a resonator, and it is loud and obnoxious. I could only imagine what it would sound like without a muffler at all.

DO EEEEETT!!!!

Apparently I'm the only one who likes it loud! I have a 3" Invidia v2 downpipe and full 3" custom mandrel bent from there back. The only muffler is a Borla-XR1 which is straight through like a resonator but it is oval shaped with more packing to absorb sound.

It's not loud enough! You can hear it and it rumbles and sounds bad ass, but when I get on it - it doesn't scream! The turbo is like it's own muffler so I saw why get another one?

In all honesty it would probably be really harsh, pingy, and metaly sounding so I would at least put some sort of small magnaflow resonator on there. It'll just take the edge off the harshness while allowing the true tones to escape.

But yeah as far as legality... my setup is pushing it. If I cruise past a cop he probably won't give me trouble but if I go WOT yeah I am getting a ticket.

I say try it out. Run the 3" with no muffler for awhile and just test it out.

It wouldnt hurt... plus it would be loud!

and if it isnt for you than put a muffler or something of the sort on

Good Luck!

The ebay mufflers do work, and quite well might I add. Granted, your turbo is small and will take some sound away, but it will still be loud and drone on the highway.

Exactly. Loud is cool at the track or rallying. Not cool on the streets where everyone has to listen to it.

Only thing I'll caution is depending on where your outlet is with no muffler, typically before the axle, you may have hot exhaust gasses aimed at your cv boot.

I plan on running the piping all the way to the rear of the car just like factory. Only just straight pipe.

At least put a 12" Glasspack or something on there. It will make it sound nicer without quieting it down a whole lot.

Ditto on the glass-pac. I put one in right where the second cat used to be, it takes the harsh tones out for a nice mellow exhaust note... Actually, I couldn't find a stainless glass-pac in that size on short order, so its actually a tractor muffler from tractor supply... the design is identical and they are far more durable. But even with that in, strait pipe was still way too loud for my new suburban neighborhood.

My car has 3'' TBE with just a Ebay cannon. It sounds AMAZING! It's just the right volume for me, but others may not like it.

here is what my '91 SS sounds like running stock TB pipes and no pipes after the rear axle. http://www.youtube.com/watch?v=V9ENiwr6f70

^ you need rolling shots and better camera skills.

it sounds like a v8 though.

im catless 3" to a custom built titanium muffler. i can take the muffler on or off with a few screws and i definitely prefer muffled.
i do like it loud, and at wot, its mean

I would have rolling shots, but the clutch is fried. Also if you read the video description, the video was shot off my cell phone for audio not video. I could have done a way better job if my goal was to shoot the car. :P

I have a clutch on the way, maybe I'll make another video once my TMIC is in along with my VF39 :D

man i would really suggest a muffler. i put 3" stainless all the way out the back. it was really loud, i liked it alot, but i got pulled over 7 times in 2 weeks. when the cops came to my door 5 out of the 7 cops said they were looking for the tractor...i didn't get any tickets because i just told them im too cheap to run a muffler but i would get one on the next pay check. so i just ebay'd a cheap stainless muffler and put it on. it sounds really good now and it...well its not real quiet but i haven't got pulled over since (except for breaking the suggested corner speed through the mountains) all in all it is just more tone with a muffler. look at megan mufflers, they are expensive but i have been pleased with them.

where did everyone find these "free flowing" or "straight through" mufflers? My muffler muffles too much for me :D

I have a 3" turbo back WRX exhaust. I think it has like 2 resonators built in .. and a straight through muffler. To be honest i bet it came from Ebay or something .. it was on the car when i got it .

BUT ... its LOUD .. shoots FIRE .. and looks good to me.

i have had some complants from older people . But my friends love it and i love it .

I say run straight pipe ! why not ? try it out and let us know how it sounds !
