Dual exhaust [Merged 7-9]

[SniperXr2]

I kind of wanted to put dual exhaust on mine, but everyone was like "no man it will slow you down alot" and I was told I would lose about 20 HP, and when you only have 140, 20 hurts. I would say if you dont care about speed, then go for it, I think it would look sweet as crap.

 

[wicked93GS]

the set up I mentioned wouldnt lose you a single HP, you might even gain from it if done right(well, you will gain for sure if its replacing the stock exhaust) ok, heres how the set up would go for a NT, 2.5" downpipe(or the NT equivalent) 2.5" universal high flow cat, 2.5" piping back to some straight through but small diameter muffler, something like a glasspack, after the muffler the pipe would widen to 3"or 4"(whichver seems to work better) and split off into 2 2.25" pipes heading out the back, you could put on some chrome tips liek the V8s use for show if you wanted(in a V configuration to eliminate as many bends as possible)

here's the deal. I do not care about top end. As long as i can beat most cars in the 0-60 or to 80 or whatever I'll be happy. I do not really feel like going 120 mph hour althoguh if I go turbo im definately gonna test my top speed, but it is not really an issue. I figure if I can keep up with the 4g63 dsms than ive met my primary goal.

The only reason I see dual exhaust for turbo DSM:
If you're runing completely ported/evo parts - exhaust manifold, o2 housing; big turbo, 3 or 3.5 inch downpipe--and that's where you split it using y-pipe into two mufflers - TO CONTROL NOISE.

Just as one or two members have stated already.....
You CAN loose horse power by going with dual exhaust, but you don't HAVE to. Exhaust is all about the balance of back pressure. You can go too big with the pipes on a single exahust and lose horse power.
Here is the deal...
We know that 2.5 inch pipes work best for a N/T setup. With this is mind, all you have to do is compensate for the DUAL pipes and figure the best size to run.
You could run a 3'' front pipe (some call it a downpipe) into a free flow converter with a 2.5 outlet, then into a 2.5 inlet and outlet free flowing muffler. Then add a "Y" pipe with 2 inch outlets. Run dual 2 inch pipes to the rear and add short 3 inch tips (just for looks).
This would actually GAIN horse power over a stock exahust,( as well as soom after market ones) could sound really good (depending on muffler choice) and would look kick ass!

no no no, he bought the car and the previous owner installed it, hes asking if he should keep it or not. Do whatever you want man, if it looks decent and you like it, why not?

We're all aware of that, I was just pitching in on some insight. The more facts he acquires, the better decision he can make himself, while not think himself to insanity.

I want to see how it looks. Take a picture

heh, sounds good. i might start working on that this summer.

Guys, you don't get it, he doesn't care about performance. He's dishing out thousands for a turbo thats not going to do much, and he wants the two coffee cans on the back. He's SHO no GO.

piping v'ing to two mufflers is ####ing homosexual in my opinion. Although, it could be good at times too, for example: When I'm driving down the road and not in too good of a mood, and I see a honda with dual exhaust/mufflers, I get a good laugh out of it, it's quite funny to see those weed wacker sounding pieces of shit rolling around =)

 

[SniperXr2]

Wow, I love how everyone on this site is so.. Nice to one another.

 

[dsmrunnah95]

Ok, I really hate to tell you guys this but more than likely if he does it like a usual dual exhaust setup he really wont lose any HP. Most dual exhaust setups split after the cat. He really wont lose much back pressure. It's just like what TurboGraphX said, with the right piping, he wont lose HP, esp if he retains his stock cat.

 

[SniperXr2]

So are you telling me that I can run a regular dual setup with Two mufflers and I am not going to lose Horsepower?
And if I am going from stock exhaust to a dual I will gain? I am not trying to sound sarcastic, but I really would like to know.

I dont know if this would work or not but instead of puting in a y pipe and having two muffler what if you ran one pipe back and had a muffler that was sideways and has a tip coming out of each end.I think that how some sunfires have it and to compare the muffler to how it bolts up look under a dodge neon but with two tip not one.

 

[TalonRacer18]

A dsm has had dual exhaust. Just check out the super street from 2 months ago, with the super street car challenge, Pruven perfomance had a gsx on there that was shoopin skylines and supras with a dual exhaust on it.

 

[TurboGraphX]

As for using a "y" pipe, or a dual outlet muffler....
either would work equally as well as the other.
you could use a rear mounted (sideways) muffler like on a neon, sunfire, etc.... or use a dual outlet on the same side, like a flow master, etc, and mout it farther toward the front wich would give a deeper sound. the closer the muffler is to the front of the car, the deeper the sound will be.

 

[LaserBrndU]

well I am buying a laser that has a straight back 2,5 inch exhaust, no muffler no cat.......might just keep it like that.

 

[kagegod]

haha you could always use the second exhaust as the dump pipe for the wastegate (if you have external wastegate). Don't know what, if any performance implications would be but at least you'd have some functionality of it without effecting the engine much (would just look like some cars in town in the cold when you can see one exhaust has gasses coming out and the other does not)

 

[DSMeclipse4G63]

I know I know its pointless but still I want it and I can find it at all. I was wondering where I can find dual exhaust for a 1995 gst/tsi? thanks for your help

 

[91 NT Eclipse]

Your best bet is to have one custom made w/canisters you like.

 

[Gooberlog]

Dual Exaust on a 4 cylinder is the definition of RICE. Don't do it man...unless they gave u a part in that new Fast and the Furious movie .

 

[DSMeclipse4G63]

its not a matter of rice....if dual exhaust was rice then stangs are rice as well. I know it doesnt serve much purpose, but I am an old school hot rodder and I just feel naked without dual exhaust. Plus I love the sound of my pace setter cat back and two would be twice as nice. I was thinking 3 in turbo back with 2.5 pace setter dual out the back(I figure that two 2.5in pipes will flow as much if not more than 3in. I dont drive rice I drive a dsm(but I do see what your saying)

 

[DeezNutsForYou]

I want the same thing on my car, but some guy at a muffler shop wouldn't do it because on the drivers side rear the pipe would have to run rught next to the gas filler tube. I don't know how the 2g's are, but hopefully not like mine. I think it would looks good, and not rice at all, unless you put coffeecan tips on it. And two 2.5's flow a lot more than one 3inch.

 

[headrec*]

DSMEclipse There IS a difference between a strait piped V8 and a inline 4 with welded on muffler tips or just a catback.

Don't do it, its pointless.

That's different b/c they have two set's of headers since it's a V shaped engine, so it would be weird to have a single exhaust on them. However I'm with the majority on this one, getting a dual exhaust on an inline engine is nearly pointless.
