Lightbulb independent dual exhuasts out the rear of RS...........

My brother just got his MY00 Toyota Tundra some custom dual tip exhausts, from a custom muffler shop, coming out the rear left and right sides of his truck. The sound is alot louder due to the muffler removed.

I was thinking that when i get my Impreza, i should take it to custom two seperate pipes coming straight out of the rear. Something like a Chevy with those Borla "straight out the back type" exhaust systems.

Anyone of you guys thought of this yet? would anyone try it? what do you think?
sounds kool ey?

Do you own a Muscle car or a Jap car?

Good luck on finding space for the extra piping down there.

hmmm...im sure its do able. but how Hard is it? and how Costly would it be. ive got a guy who can and will put duals on ANYthing. its mostly a $$ issue.

would anyone do it??? probably not, i wouldnt anyways. cuz, the duals w/ big old tips are for american cars, V8s, big bass and window shaking rumble. ive got them on my 85 Fullsize Blazer, but thats got a 5.0L V8, lift kit and the works. ive also got them on my 79 Trans Am w/ a 6.6L V8, set up for Race. and ive got Duals on my 88 RX7 just cuz it was Factory w/ duals.

Euro and japanese rides are Way more sophisticated, and dont require Duals to turn heads, what you Need is a Stromug or Greddy, or HKS exhaust. and if Thats not loud enuf for you, just go the that exhaust shop, have them take off the muffler, and put on a 2.5" pipe, w/ a 3.5"x 20" chrome resonator tip. THATS loud. thats what my friends like, and thats what i do on their cars.

any ???, let me know

You COULD put duals on a Subaru. The boxer engine design would make it quite easy, but would you want to?

I mean, have you ever heard a Subaru engine un-corked? They sound really, really funky.

Strait duals on a Subaru would would probably sound like a slant-6 schoolbus with burnt valves....If you couldn't beat someone in a race you could at least scare him to death....

I think it would look nice to have too pipes coming from the back, With the mufflers it would be nicer. Maybe it would have even a nice affect on power too... Is there any available?

The dual would be interesting to hear. I have a 3in straight back with no thing but 3in pipe, no muffler, etc. I love the sound, it has a very Italian supercar sound. I imagine a dual would sound more like a ricerocket streetbike.

Yer kind of missing the point of a dual setup. You use a dual setup on V8's, and some V6's because you can't put a big enough single pipe on it to breathe well. If you put a dual setup on a 4cyl, you would have to use tiny exhaust pipe, even with a turbo, or you would lose all back pressure and your car would have no power.

Think about it. Even with a turbo, a 3" exhaust is about right to balance the exhaust. So, that would give you a 1.5" dual setup. That'd sound really good, wouldn't it.

The only way I think it would look good is if you incorperated it with a GT style body kit, either exhaust exiting out through a rear bumper or my favorite... duals exiting out of the side skirts, just in front of the rear tires. It done right and properly set up to produce a low, not loud tone, I.E. strogumn sound or STi sound, then it would look and and sound pretty good. True it is a Jap car, but it can still get some domestication. afterall the Focus is a japanised Domestic, why not reverse it for the Sube? I like my STi out the back just fine, but would like to see someone else blow there $$$$ on dual exhaust coming out the side skirts, that'd be kinda coo.

Gavin> Not to be a dick by correcting you, but your math is wrong.

The area of a circle is <IMG SRC="http://www.flat-four.com/images/pi.gif" border=0>r<sup>2</sup>.

With a 3" exhaust the cross-sectional area of your exhaust would be 9<IMG SRC="http://www.flat-four.com/images/pi.gif" border=0>. Half of that would be 4.5<IMG SRC="http://www.flat-four.com/images/pi.gif" border=0>. The square root of 4.5 is 2.1213 so the 2 new pipes would be about 2" diameter.

Hey- I had dual side pipes on my legacy. That was free flowing. It was LOUD, but the power was there. it robed some down low, but what it gave back over 3 grand was well worth it. Alas those damn RR tracks on richmond parkway, ate my exhaust... twice, so now I have MRT.

Yeah, I knew the math was wrong, I just wanted to make to point. Your engine has to produce enough exhaust volume to make a dual feasible. I don't think there's a 4cyl on the planet that does.

Puckeveli is right and this is what I was trying to tell everyone in the first place.

The black "thingy" is the charcoal canister for your fuel system. It is right behind the passenger rear bumper side only on the newer Imprezas. The older Imprezas had them by the driver's rear seat area.

do you guys seriously think that dual exaust like the the ones on v8's are needed? our boxer engines start to lose low end with 2.5 midpipe not to mention what dual exaust would do to your lowned. even some v8's lose lowend. it could be done if you have the money but not really worth the loss of almost all your low end just for cool sounding exaust.

I did a little reseach on this with a custom exhaust shop in Cleveland. To get a tip to come out in the middle(ala Porsche Boxster) the spare tire well would have to go. To get tips on both sides the "black fuel thingy" would have to go. I can't remeber what it is but I know it would most likely give you a C/E light without it. To get them to come out on the sides before the rear wheel. The heat shields and such would make them stick out under the car.

I have thought about doing a dual exhaust tip on mine just to do something different. I would not do a true dual exhaust though because the extra pipe running down the middle would just weigh way to much when you factor in the loss in low end torque. What I wanted to do was split the pipe just before the rear diff. and have dual tips sticcking out on each side. This would make it impossible to have a muffler on the passenger side though and you would have to go with some sort of resonator tip. The end result I think would end up somewhat like a honduh so I never wanted to try it. Not to mention it is illegal where I live and it may have some problems passing DEQ. I may be totally wrong about this but I don't hae the money to find out so if you want by all means go ahead. Just please inform us as to how it works out so if it is bad no one else makes the same mistake. By souding honduhish I meant too high pitched. I like the low growl mine has right now. One word of advise to you though, 2 1/2" exhaust is a bit too big. Go with 2 1/4" and you should be much happier with it. If I can ever afford it I will be geting 2 1/4" on mine, 2 1/2" just takes too much away on the low end wich is what I use the most.
