The power difference should be less than 10whp, probably more like 5whp if anything at all. Maybe if you had a bigger turbo it would make more of a difference.

As for weight, the single will probably be like 40lbs less than stock (the OEM axle back is heavy). Compared to an aftermarket quad tip, maybe only 20-25lbs less. My exceladyne axel back is much lighter than the stock one.

To be honest, I would estimate gains far less than 5 whp with a single versus a double. Getting a single is more of an economic and weight equation. Torque won't change based on the weight of the car -- only the resulting speed will -- so rather than any actual output gains you're just looking at getting better use out of the existing torque. Any of this would be to a very low degree, though: literally less than a 1% improvement in curb weight.

[edit]For sake of clarification: I'm referring to the car as a series of systems, where torque at the wheels will not change. You will see no significant dynamometer improvement. However, on real road conditions effective acceleration would technically be higher as the weight is reduced.

Biggest thing is the difference in piping diameter. 2.5" vs 3" exhaust and a 3" exhaust has always made more power especially on a turbocharged engine.

Why bother estimating when ark already dynod and showed more than 5whp difference in favor of the single? That was on a stock tune as well, would most likely be a bigger gap with retune and/or bigger turbo.

Br said in another post that their exhast is heavier than stock by a few lbs..

Ugh, I'm STUCK.

I want performance, haven't had an issue with single-exit's before

However I feel this car was made for quad...

HKS sounds great and looks great...(my choice for quad tip...)

Greddy Single exit is nice...

TurboXS single exit is a bit cheaper then the Greddy.

I can't stand the look of a single exhaust exit. Every time I see a large single exhaust, I think "Holy **** fart can, what a ricer."

 

[Charisma]

Let's face it, logic tells you the dual exhaust doesn't affect performance in a positive manner. At that point, it's all a preference. Do what you want.

 

[khergan]

Single exits generate more power.

Single exits weigh less.

Single exits are less expensive.

Single exits are less restrictive and have straighter piping.

What's the question again?

 

[smoke]

yea look at all those ricers.... If you want to classify our cars as having a fart can like a honda civic. Then you must be....

 

[infeKteDx]

That last car is pretty ugly...

but I mean, I've heard a "fartcan"....they sound horrible.

This is the soundclip for the TurboXS Single-exit catback:

http://turboxs.com/media/Genesis RS Exhaust Idle Rev.wav

I don't think it sounds like a fartcan at all.

I understand it makes the car look a bit rice, that's why I'm leaning towards the HKS quad exit exhaust...but I can't say I hate the TurboXS single-exit.

*** Video I found on youtube of some hicks making fun of a ricer lolz ***

"Can you hear it over the diesel?" ahahaha....I hate red necks >.>

 

[khergan]

Let's face it: most civics are ricer attempts at LOOKING high performance without actually shelling out to be high performance. The ubiquity of "fart cans" on civics is just a marketing gimmick to make people think they are going faster or make their civic sound more intimidating.

However, this gimmick that gives "fart cans" a bad name is actually a very successful design in high-horsepower turbo cars with inline engines. Notice how the Supra, the Evo, the STi and even the GT-R have single exhausts...for a reason. It's also not a coincidence that Silvias all rock "fart cans".

THEY GIVE BETTER PERFORMANCE, PERIOD. THEY ARE ALSO LIGHTER WEIGHT.

Let's face it, dual exhausts on an inline engine are rice, period. They're done more for the appearance of power than actually generating it. If you're concerned with performance, you get a single, period. If you want to fool people into thinking your de-badged Genesis Coupe is some twelve cylinder exotic that actually warrants quad exhaust, go for it. But unfortunately, you're basically playing in the same camp as the ricers when they stick a $25 Folgers can on their civic; trying to fool people into thinking your car is better than it actually is.

 

[infeKteDx]

Khergan, correct me if I'm wrong, but do I see quad exit exhaust in your pic under your name???

I'm not trying to be a jerk, I'm seriously asking, it looks like you have a quad exhaust.

 

[flylow]

Dual= cosmetic trend every little 4banger has from the factory nowadays!

Single= its how it should be PERIOD! 100% functional

 

[khergan]

Got the ARK single

Also

Quad tip on 2.0t = wants to look like a V6/V8/V10/V12

 

[R-SpecGen]

Does anybody have a good picture of a single exit exhaust with the cover piece on the rear bumper?

 

[CrookedH]

They show one of the angled single exits on that page, not my favorite look, I like the straight tip like UR and DC have...

[R-SpecGen]

Yes I did see that picture from Importshark.

However something further away would be more ideal.
