    Absolutely amazing quality. Wasn’t too hard to install the springs either. Pretty easy to install aswell. Now the bolts weren’t standard nor metric Allen keys so we used a socket star bit(don’t remember the exact size). It worked great but you have to be careful not to strip it still since it isn’t a prefect fit but we were able to torque it.

    Soooo loud and amazing 2 years ago
    5out of 5stars

    This thing is one of the best things I've bought for my car. The turbo spools up way faster and you have torque way earlier and once it opens up it's the loudest thing I've ever heard and it's amazing. I would highly recommend this to anyone

    Love it. 2 years ago
    5out of 5stars

    put this one on along with other items such as: Killer B headers, ID 1000, GS up pipe, invidia catless DP, upgraded 16g 6x6 stock turbo (port n polish), and tgv deletes. I had the springs set between 10-12 psi. I think it's 11.8. Definitely loud once you spool but really amazing. it's loud once you spool, but on a regular cruise, you should be good. therefore, not annoying. my car pulls quicker now and turbo response is better. Customer service wise, I first ordered the 44/45mm but had to return it due to advice of my tuner (cause I'm stock turbo still) and RSD helped me once i explained the situation. It was open box but never installed. So thankfully they helped me with it. Guys from the chat room also helped alot in answering my questions and the return process. Overall, thankful for the RSD team in helping me purchase this product. I'm not really doing pulls or anything cause I installed fuel rails and fpr, so i'm only limited for now in enjoying this product. But once the retune is done, I will update my review here. Once again, Thank you RSD and Tial. Install's a PITA.

    This wastegate SCREAMS. I have a stock turbo, downpipe, up-pipe, and more goodies nothing too crazy like rotated. But even with a" lightly" modded car, the wastegate has a perfect pitched tone. It almost scared me when hitting boost for the first time. Great quality product.

    Going EWG was a fantastic choice and this was the one almost everyone I know recommended. My turbo spools so much faster and the awesome scream when this thing opens gives me a huge smile every single time I get into it. Kind of a pain to install this and the up pipe and dump tube without a lift and with my not so great down pipe, but other than that all went well and smooth.

    • Q: EWG with catted DP  Gabo 5 months ago

      Does it worth using EWG w/catted DP? Looking for more controlled boost and sound too!
    • Q: 05 STI vf39  Ayayron1 year ago

      Will this wastegate fit on my 05 STI. I just have a stock vf39 turbo that's been port and polished.
      • 0 of 0 people found the following answer helpful

        A:  Yes it will but you will need a place to mount this, either the downpipe or upppipe and a wastegate bracket as well as a protune. I would consult a tuner before purchasing.

      I can run a 44mm on a stock tubro with down pipe intake 1000cc feul pump and headers Will it be fine or the 38mm is better?
      • 0 of 0 people found the following answer helpful

        A:  If setup properly you can run either one, but depending on the boost levels or your turbo plans for the future one setup may be better than the other.
