While that might be true but this isnt an appearance mod

The X02 is a solid performer and one of the best exhausts (power wise) that the board has seen ESPECIALLY for the price

If it looked like borla or whatever no one would really care....they are some pipes that make power and cost 550 shipped....the fact they even look like HKS is a very very distant second to X02 owners (from what I have seen) I have yet to read someone post...oh they look maddd JDM tiiite yO I am gonna buy it and keep it sHinY yO...

This exhaust does much more than look nice, much more and the dynos prove it

 

who said anything about appearance? clothing is clothing right? does fake and real brand name clothes physically do anything different for you? no, they both serve their purpose and cloth you. Folex vs Rolex? they both tell time don't they? hks and xo2? they both make power. thats the point im getting at. the xo2 didn't just happend to look like the hks by coincidence, either way you twist it, its a knock-off/fake. if it were to improve on the design or offer something other than $$ savings then it would be a different story.

 

It does improve the design, it doesn't sound like sh*t

 

lol, i have no doubts that there are hks' out there that do sound like **** thanks to the major pipe blockage, i wonder if they sorted that problem out

 

Lets settle this.....
Post sound clips of an HKS with tp's and one of an X02 with tp's

....and some numbers.

 

No reason at all not to get it, if you have the money and that's what you want.

 

No test pipes but HKS:

XO2:

XO2 just sounds deeper/throatier to me. Just my .02

 

Why would anyone want a fake HKS? Just get the real deal and call it a day. It'd be one thing if the cheap x02 knockoff improved on HKS's design, but it doesn't. It's just a cheap imitation made out of cheap material that will not last... Next thing you know walmart & target will be selling x02 cause it's so cheap quality-wise. Lol! :-)

Yep, that'd be pretty cool pulling up to a Z meet and bragging about your cheap walmart brand x02 exhaust that you got off the clearance table!! LMFAO! The honda guys will luv ya for sure! :-)

If you're on such a tight budget that you can't afford a real exhaust, just please don't also drill holes in your bumper for a diy cold air intake, or rattle-can race stripes to match your cheapness. Lol!

 

Expensive does not equal better

Post a single link to the X02 failing because of quality, its been well over a year since they began selling them....I bet you we can post a link the H pipe fiasco from HKS

This isnt a 100 coffee can weld on muffler....it $550 and makes power

Stainless is cheap now?

I will hopefully be getting my hands on both systems to test on the same dyno in the future....you can bet I will post the results with graphs and impressions....so far 12-18whp gains for $550....I dont see the downside, no quality issues....just alot of bandwagon riding and name calling....no facts presented to say why people even feel the way they do

 

ur an idiot/

if ur car sounded like that, and u thought that sounded shitty, ur crazy.

i'm anxious to see ur exhaust setup now.

 

Call me crazy if you want. Like I said, personal preference.
I've had HKS+TP and HFC, Nismo+TP and HFC, Greddy Evo2+TP and HFC.
The only reason I went back to Nismo(besides the fact that HKS won't clear my TS CF diffuser) from HKS is because I couldn't stand the sound of HKS.

 

sounds like **** to me...

 

the crawford plenum could posssibly change the sound

 

Crawford plenum, Motordyne plenum spacer..pretty much same sh*t..check my sig for my mods.

 

Because it's cheaper, yields good gains, doesn't sound like poop, didn't have to hack apart the h-pipe because of quality control issues (See: HKS, Improving on perfection LOL) and we don't feel we need to waste money on a product that costs at least 2x more, when the cheaper version is more to our liking.

Getting the XO2 had nothing to do with my budget. I could easily afford the HKS exhaust, but I didn't because I liked the sound of the XO2 much better. It wasn't about it being a cheap HKS to me, it was all about it being a nice sounding exhaust, the price tag is just an extra benefit. So if you could please step off your HKS soap box, that would be great.

 

It's all good! I was just trying to stir **** up! Lol! To each his/her own. Yes, the batch my hks came from did have some quality issues, but I got 'er all fixed up... Seriously, I haven't seen an x02 in person, so I really can't comment on it~ But an x-pipe would be an improvement over an h-pipe on any exhaust... h-pipes are cheaper to manufacture, so that's what they usually come with... :-)

 

Haha, it kept me entertained at work for a little bit. An x-pipe may make a little more power up top, but I heard x-pipes can cause rasp, where the h-pipe will make the exhaust sound deeper. I like how throaty the xo2 is so I'll forgo the extra few ponies and probably keep the H.

 

What ever floats it for ya, but I think ya got that a 'lil backwards there chief~ now you're trying to rationalize why you should keep the inferior h-pipe on an inferior exhaust...

Here, lemme help ya out a bit:

Although X-pipes are essential for race cars, adding this modification to a stock car can be a good idea for many reasons – increased power, fuel economy and less noise inside the vehicle. This type of aftermarket performance part is something you can either purchase or have custom-made for you by a good muffler shop. Installation is simple enough for the at-home pro, and the result will be well worth the effort.

The Evolution of the X-Pipe
To understand the importance of the X-pipe in relation to improved performance and power, you have to know about its roots. The X-pipe is really the offspring of the H-pipe design, which was first conceived in the 1960s by the major American car manufacturing companies at the time. Duel exhaust pipes for V-8-powered vehicles are very noisy, as there is no sound wave cancellation between the 2 separate four-cylinder engines and unconnected exhaust systems. Engineers were looking for a way to cut down on interior noise levels and improve the engine's power. They realized that running a balance tube between the two branches of exhaust pipe would work to broaden the torque curve (thus improving engine performance) and dissipate sound resonance in the exhaust system.

In the 1990s improved technological advancements made it possible to construct an exhaust pipe that, instead of connecting by means of a balance pipe at a severe 90-degree angle, could unify the two branches of pipe to create a flow of exhaust in one direction. Now X-pipes are being manufactured for popular performance cars, usually off-road versions minus catalytic converters, but you can also find them in legal models fully equipped with proper emissions equipment. Performing an X-pipe mod is an option that you should consider.

Why X over H?
It has been proven time and again that the X-pipe design is more efficient than the H-pipe. Various tests have shown that for multiple cylinder engines the X-pipe outperforms H-pipe exhaust systems, especially as rpm increases, providing both better torque and power. Unified exhaust pipes work most efficiently with multiple cylinders because of the scavenging effect. With exhaust X-pipes the almost seamless connection between the two exhaust pipes allows sequential firing cylinders to salvage any spent exhaust gases from the combustion chamber more efficiently and creates more room in the cylinder for a fresh intake of undiluted fuel and air. When you have two exhaust pipes, as the velocity in one header tube increases, the pressure in the adjacent tube is lowered causing the exhaust to be sucked out of that cylinder. X-pipes are simply better at doing the job, especially at higher speeds.


Installing Exhaust X-Pipes
This is a simple mod that almost anyone can perform successfully. Most companies produce exhaust X-pipes that are simple bolt-ons that can be installed in less than an hour using the usual hand tools.

If you own a vehicle that doesn't have an X-pipe available, it is possible to have a custom X-pipe assembled for you. A muffler shop can construct it by taking an X-pipe union and bending up some exhaust tubing until it fits. If you decide to make your own exhaust X-pipe from scratch, so-to-speak, remember to place the X-pipe union as close to the rear of the vehicle as you can to increase the power.

 

Uh-oh someone learned how to use google! I never disputed the fact that an x-pipe would be more efficient, or put more power to the ground. I said that I like the throaty sound of the xo2, and that is partially because of the h-pipe. If you want I can google too? I just rather not hack apart my exhaust to put an x-pipe in just to gain 2-3 rwhp.
