Dual Exhausts

Okay. I found this ad on ebay for a dual exhaust and it is quite cheap. I'd just like to get some facts from you guys as to how this would compare to other exhuasts. If this is good as it is, the I'll probably get it, because as I've said in other forums, I'm pimpin out my car on a budget. Here's the link: http://cgi.ebay.com/ebaymotors/aw-cgi/eBayISAPI.dll?ViewItem&item=1803756720

Also, if anyone has any suggestions for other cheap/good exhausts, please give me some insight. Thanks

K, first of all, that is not a dual exhaust, that is just a dual tipped muffler. for $100, I think you can get something better than that. But just so you know, that is not a full catback system, it is just the muffler, so you have to pay for new piping (if you want the performance part of the exhaust), but I doubt this muffler can get you any sort of performance anyways. I would suggest you scrap this idea and go with an actual catback system.

Thanks for the reply . As you may have guessed, I'm a big n00bie, so any input is good input. Thanks

How do the Hp Racing, Apexi, and Greddy exhausts compare?

I don't know anything about HP Racing, but Apex'i and Greddy are two very reputable companies, and make very good exhaust systems. More brands to keep in mind are Thermal R & D, or Tanabe.

Don't waste your time or your money on ricer shit man. When it comes to modding your car, if you cut corners and go the "economical way", you're going to mess up your car. If you want to buy an exhaust, buy a cat-back. Can't afford it? At least spend your well-earned money on a respectable brand such as GReddy, HKS or Apex'i.

Exactly. Spend the money on something that is worth the while. Companies such as GReddy, Apex, HKS, thermal R&D, tanabe are some companies to think of. Save the money and buy a catback.

I wouldn't buy something just because everyone says that it's the shiznit...I would get a muffler and get custom amde piping from the cat back....I'm using a Dynomax(domestic brand)and it's beautiful

What's so different about different exhausts and brand names? An exhuast system is just a fancy name for piping(whether it be stainless or not)and ending with a big can with steel and fiberglass packed in it....

If everyone says its good, then why wouldn't you get it? You know your not getting a bad product. The difference between exhaust and brand names is the way they make the exhaust, you could go get a universal muffler then do custom piping, but these catback exhaust have been tested numerous times to find the optimal performance, and also the cat back is made specifically for your model of car, so its not just any ol exhaust. You will probably see better gains too with a brand name exhaust company rather than doing it yourself.

show me physical proof that a greddy exhaust produces more power than a custom catback exhaust....that's just like saying that a revhard kit or a drag3 kit is better than a custommade turbo setup.

everycompany makes their mufflers and exhausts the same way:1. they bend the piping for the car, 2. they pack the muffler and either weld it or rivet it, 3. they weld on the muffler to the piping....

as for application specific, isn't that what customizing is?

here is my .02

1. Dual exhaust. true dual exhaust was eliminated with the catalytic converter and obdII with the dual O2 sensors. it is virtually impossible (shy of have the computer reprogrammed it that is even possible) to run true dual on any car with 2 O2 sensors. as for true duals on a 4-banger cant do it. well you could. but you would lose performance.

2. Which is better. a pre made cat-back will offer you the best gains that company could get out of their R&D while still making it economical. only way i would do custom piping is if I or the person doing the piping knew tons about exhaust, gas flow, and other princibles like that. and last time i checked most muffler shops could tell you which way the gasses flow and thats about it. the only way to get a proper custom piped cat-back would be to dyno tune several designs, which is what a Greddy, Apex, Tanabe exhausts are. they were, i am sure, dyno tuned to offer the best resulst for that muffler. granted different muffler designs will offer different advantages. as for the personal opinion......i hear tons of people raving about a group of guys who modifies imports. well they told me they could put a turbo on my car. these same guys can't 1. install a clutch 2. replace suspension bushing. and 3. one of them was up at O'Reilly's the other day. whining about a bad spark plug, because it was fouled out. the other three were fine. but this one just HAD to be bad cause it fouled out. (NGK plugs on a 90 integra) well i looked at the plug after he left, it was fine...not a darn thing wrong with it.....anyway moral of the story, just because a large number of people say something is good doesn't make it good. the best proof are dyno proven numbers.

again ...just my .02

That's not the same. When you do a custom turbo, they turbo is made to exact specifications to your car, and made specifically for your car. When a "custom exhaust" is made, there is no research or anything done before hand. It is merely slapping a couple pipes together to put an exhaust on your car. With a custom turbo, one is made for your needs (whether its on the drag strip, or daily driven), and that is why it is different. When you go to a shop to do custom exhaust, all they do is put a couple pipes together with the muffler you supply, there is no actual custom work done for your car. With a catback, like White97Ex said, with their R&D research, they have gotten what is the best for your car.

I see what you're tring to get at, but what I'm trying to say is that how do you know they did all that R&D? Just because they say that in their ads doesn't mean that they actually do it....plus, why would you pay 600 bucks for 2-3 horses more than a 130 dollar custom system?

Well, ultimately, the choice is up to you.
I can't say that I do actually know they do R&D for their products, but its been proven they have significant gains on their products. They have dyno charts and even people that have their product can stand behind it. So its really up to you. I know $600 is a lot of money, so if you would rather spend a significantly less amount of money, and get similar results (if the exhaust is done properly), then go for it.

I have seen many times OBX Mufflers blowing the packing out much faster then a Greddy System. Also a big diffrence is also the sound. You can get a OBX and keep getting pulled over by the Police or you can get a very quiet Greddy and not get pulled over at all. Well... at least not for loud exhaust. Please do more research.

I've seen on some a tunable silencer, does that affect performance?

I have a dynomax and they are gauranteed for life....plus, if you have problems with blowing out the packing, then you got something else wrong with your car...otherwise, buy a rebuidable muffler like the x-tec. I had one before, they were loud, but they were not raspy.

It may have a lifetime warrenty but would you rather pay a lower cost and have to worry about taking off your exhaust and sending it in to get it fixed or even have to rebuild your exhaust when you could just buy it once and not have to worrie about it anymore. Sorry I am not the type the buy Auto Zone shit and have to keep getting it replaced or repaired. Have a nice day.

try a dynomax and you will be convinced(this is the bang for the buck theory here)...as for the xtec mufflers, they can be rebuilt on the car...

I will do more research into the Dynomax. I Will take a look at it but I just bought a Greddy PE Cat-Back for 250 dollers. Used of course but it was owned by a good friend of mine that just bought a Mugen Twin Loop.

Yeah, it does affect performance.
It hinders like 1 or 2 horsepower.
Its like sticking a banana in your exhaust.

You lose like 1-2 horses in high end. But you do gain Tourque in the low end because of the needed back pressure unless you have some kind of F/I

What are you talking about? Duel Exhaust being gay?
