    If you're looking for help and want to draw people in who can assist you, use a descriptive subject title when posting your message. In other words, "I need help with my car" could be about anything and can easily be overlooked by people who can help. However, "I need help with my transmission" will draw interest from people who can help with a transmission specific issue. Be as descriptive as you can. Please also post in the appropriate forum. The "Lounge" is for introducing yourself. If you need help with your G70, please post in the G70 section - and so on... This message can be closed by clicking the X in the top right corner.

it's available for sale now, videos for 2.5 and 2.5 are in the listing, kinda pricey imo

 
If someone stateside offers this for the 3.5T and it turns out to be reliable I'd be very tempted.
 
sounds good! Can’t wait to see what else comes out!

They already do. Runs about $2400 for the kit. Seen a bunch of videos from the asian market sounds good and they are apparently a well respected brand over there.
 
Decided to try it out. Just arrived. Great service so far. Was here from So. Korea in less than a week. Good communication through EBay. Seems like they have a good marketplace rating as well. Seller is a third-party who lives over there and orders directly from company. Going out of town so won't be able to put in until next week.

Did you get it installed? Thoughts? I’m interested but wanted to get stateside feedback before ordering. EBay seems to be the best option.
 
That's interesting. So how do you open and close these valves to make that sounds? Also, while driving can I open and close them accordingly if I want to hear less sounds or more?

Has a remote for the system, key fob looking piece that allows you to adjust the valves open or closed while driving.
 
  1. Ok guys here are my thoughts: I bought this on eBay and installed it.
  2. Came faster than they said.
  3. They contacted me to verify what engine I have(3.5TT)
  4. It does not come with install instructions. When I contacted supplier, they also did not have instructions according to them since it was so new. I can give you my non-invasive instruction guide that I had to figure out. 😡
  5. How it works? It opens and closes a valve operated remotely. The valves are controlled with an air pump that has to be plugged in.
What are my thoughts?
  1. Price is TOO EXPENSIVE $2,461 shipped + install. This can run $2,600.
  2. Quality (build) is great
  3. Clean install. Looks like original.
  4. Install of actual muffler is bolt on easy.
  5. Lack of instructions is vexing. Literally you get all the parts and you have to put together the jigsaw. Why Vexing? Because your car is brand new. You are concerned with voiding your warranty. You also dont want to permanently physically damage your vehicle with install errors.
  6. Not impressed at all with sound. As a matter of fact VERY disappointed. Did i say too expensive? The difference in sound from original from 1-10 is maybe a 3. It definely does not sound like the video. Now maybe I did something wrong and I am willing to try any advice given here and to change my review.
  7. To be honest i plan to contact the maufacturer tomorrow. Maybe i got a defected unit. I dont know. I am really willing to put the original back on and sell this.
  8. Price is TOO EXPENSIVE for the difference made
PS installed JB4 Tuner for 2.5T, 3.5T, SmartStream, and K5 (BETA)
WORTH EVERY CENT!

Damn, was excited when I heard the video clip….back to drawing board, gotta find something that sounds better than the sewing machine sound of the stock exhaust…..

Hey did you get this installed? what is your view of it? Am I off?
 
Sorry for the delay. I've had it in for about a month and a half. Super simple to install. Have connections with our local Hyundai and their service put it in for me. It comes with a key fob so you can turn it on and off. I keep in center console. You really hear it kick in when you are in sports mode and higher. Internal sounds like a wind machine, pretty cool. As for external in idle. Noticeable difference but depends on what you are looking for. If you are looking for your GV70 to sound like a muscle car, this ain't it. A friend of mine has a little Veloster N line with XForce, a little less than that but noticeable improvement over factory.

I have to agree with you here, the cost doesn't seem to justify the results if you want loud. I was expecting a little bit more of a punch. Strongly thinking about sending it to a custom pipes place locally. Just wondering if I am going to sacrifice the quiet inside in order to get more sound on the outside.

Any chance you can post some real
Life sound clips, idle/internal rev and external rev/driving-acceleration? No big deal if you can’t, just wondering, im on the fence. Need something to upgrade the exhaust but don’t want to spend $2k+ Just to go from whisper to loud whisper…….
 
Sorry to necro this. Does anyone that has this installed have a clip of it? I'm generally willing to spend the $2k for a small change, but if it doesn't sound like it does in the video (which I don't really understand how that could be unless they designed a different system to make the video which makes 0 sense, I guess it could be downpiped or something), I'd like to verify what it sounds like.

Anybody come up with any other options besides a custom job? Idk if I trust any of the idiots around me to fab an exhaust beyond welding a cherry bomb to a straight pipe. Anyone that has a custom system have a blueprint?
