Dual Exhaust Systems on our 240's

[240sBoMex]

Has anybody here ever put 2 exhausts on their 240sx, namely 95-98? &nbsp;I mean one cannister on each side of the car.... im thinking about it but i heard the gas tank might be in the way of the 2nd cannister, and this will result in much torque and HP loss. &nbsp;Somebody help me out and clear up this foggy mystery!! <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/sly.gif" border="0" valign="absmiddle" alt=':sly:'>

[boosteds14]

anything can be done, with money,
but why? i think i looks ugly
u may need to have totally different bends in each side

[AceInHole]

I'd say it's more feasible on the S14 than the S13. &nbsp;On the S13 the gas tank is where the pass side exhaust would go. &nbsp;It looks like it would fit pretty well with some custom brackets on the S14.
As for power.... &nbsp;it really wouldn't be too bad if it was designed well. &nbsp;The N1 Dual is a dual exhaust that some use for NA applications. &nbsp;If you were to simply route one of those pipes to the other side it would be a "true" dual exhaust. &nbsp;
The biggest concern I'd say is the added weight of a 2nd exhaust muffler. &nbsp;
I'm pretty sure there used to be a pic of an S14 with a dual exhaust around, too.

There is a company (HKS?) That makes a dual exhaust for the S14, check out some oversea's sites (might be called HKS super dual dragger) can't remember. I think it would look odd on a S14, the S13 looks like it should have dual but like stated earlier it would be hard.

[Yoshi]

ok, someone correct me if I'm wrong....
BUT, if you are putting duals on a small displacement engine (ie most 4-bangers), doesn't it have a negative impact on output performance (provided the 2nd exhaust isn't just a dummy pipe for rice value)??? &nbsp;I remember reading something about the lack of backpressure draining all the torque out of low displacement, high output engines... &nbsp;can someone verify?

[XylathaneGTR]

Yes, its possible...
It will add a bit of weight, and lose a bit of HP...its mainly for looks...
Some people, just bolt on a 2nd fake exhaust...like, the muffler and a peice of downpipe, jsut to make it look 'nifty.'
But Yeah, it can be done...but you gotta admit, sometimes 2 4inch Exhausts does look sorta cool &nbsp;<img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/biggrin.gif" border="0" valign="absmiddle" alt=':D'>

Ehh,
I don't think HKS makes a Dual for the s14...im pretty sure anyways...
They make a dual for only a few Cars, NSX and such.
HKS mainly has 2 exhaust systems for a 240.
The Hiper, at around 500dolla, and the Super Drager, around 700 dolla.
Unless theres one in Japan, i havn't seen it (the dual)

[96SEChick]

You can find the dual exhaust on Stillen's website.

www.stillen.com
select your car and scroll through the list almost to the bottom. &nbsp;It is part number 502530. &nbsp;It is HKS DRAGER/DR 240SX 95-98. &nbsp;It's a bit pricey, though.

[Ni5mo180SX]

I dont thnk you'll lose power really.

[misnomer]

Depends on how it's done. Either way, it will look tacky. And you WILL lose power unless you know what you're doing. Routing it around the other side puts more bends in the pipe, along with the split, all adding turbulence. I'm sure there's a way to make a split pipe work properly, but it would still look poser on a 4 cyl car.

... and they you could add on like FOUR more exhausts... and paint it teal... and put a big wing on it with little things hanging off of it... and... and... and... <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/butbut.gif" border="0" valign="absmiddle" alt=':but:'>

Actually, contrary to common belief, backpressure does not equal low end power. The reason a large diameter pipe kills low end is because at low RPMs there is very little exhaust actually flowing through the piping, and a small amount of exhaust in a big pipe means turbulence and less free flow.

So two small pipes with an area equaling that of a single 3 inch pipe will retain low end power, but still allow for high end power.

Mark had the HKS dual Dragger on his S14, but I'm not sure if HKS makes 'em anymore. It looked really nice though, I liked that exhaust. There was one for sale on ebay about a week ago, I'll try to find the link.
The Trust(Greddy) DD is also a nice dual, I think only jspec.com sells em so far.. but they all come out one side of the car.

www.stillen.com still shows that exhaust for sale. Here's a pic:

Well, I tried to give ya a pic, but I can't seem to get it to work on the new board. ARGGGG.

HOLY SHIT...
WHAT DID THAT PERSON DO TO THAT INTEGRA? My God!
thats some funny shit...
btw, u meant that kind of exhaust?
oh...
I thought u meant the kind...with like, 2 mufflers, like, on a 300zx or NSX.
(ie, this kind)

it looks like the picture was photoshopped

They're not photo-chopped. Here's the 3 pictures that were posted before.

[HippoSleek]

My apologies if you were looking for an exhaust with a dual outlet (like the Greddy DD or the HKS), rather than a dual exhaust (like that *thing* <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/crazy.gif" border="0" valign="absmiddle" alt=':crazy:'> ). &nbsp;(I'll hope it was the latter).

[boOmbaa]

wow, k thats alot of $$ for the HKS system, and im not really crazy bout the exhausts on the pics, but this is what im thinking... &nbsp;Ill buy 2 of these...
Tanabe Style Exhaust (http://www.procarparts.com/store/displaydetails.cfm?pid=Tanaba-RS-MF)
and then get a muffler shop to custom build all the rest of the piping so that it goes kinda like this &nbsp;]----- or like this ===== all the way (sorry for the bad visuals) ...and 2.5" throughout to the cat...could you tell me if this sounds good or horrible? <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/hmmm.gif" border="0" valign="absmiddle" alt=':hmmm:'>

Here’s an S14 with a dual setup, looks like a custom bumper too.

[sykikchimp]

I think a setup like whats on the 300zx would look sweet with a nice body kit (Cut and molded to fit that look in the back).

Of course it would be purely for looks. &nbsp;Not really practical for performance though, b/c of the extra bends. &nbsp;But I doubt it would cause that much of a loss. &nbsp;Also 2.25" or maybe even 2" would probably be better. &nbsp;2.5 is a smidgen large for an N/A 240 with a single pipe.

[240sBoMex]

then how bout the sound? How would you get it to sound more like barry white even thru higher revs...i heard a story that the deep rumbling sounds best come out of straight cannon style cannisters (like the shape of sportbike exhausts)...and has anybody had experience with the Tanabe Racing Medallion exhaust (oooo so niiice)?

[Grant]

I believe that is the european S14 rear bumper (with black trim painted red). Ask Dave2u, he would know. What kind of wing is that?? althought a bit high, still looks really nice.

[Yoshi]

Transient,
actually everyone for that matter....
I thought he wanted old skool type dualies <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=':)'>

he just mentioned dual exhaust, so i assumed he meant just separate mufflers, not catback originated type, as in the Dual N1 or anything... I was thinking having 2 3" pipes running the length of the car would adversely affect things, but if he just wants the dual n1 type with the pipe diameter changes to compensate, I see no reason for significant powerloss...

my bad everyone, communication goof &nbsp;<img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/wow.gif" border="0" valign="absmiddle" alt=':0'>

[thewholefnshow]

Wow... that is really, really really ugly. Man, ugly. But maybe if it were dual n1's or something pointing out, but that looks like 2 12$ mufflers...

I could be wrong, but I'm pretty sure that stillen dual exhaust is actually a 300zx exhaust. I'd love to have a super clean dual exhaust (4 tips) ala the 2002 M3. (mmmmmmm!<img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/wink.gif" border="0" valign="absmiddle" alt=';)'>
