  1. Fantastic quality

    Posted by Adam on 8th Feb 2020

    First off, I'd like to say that the customer service with Boosted Beauties is superb. Although my diffuser took about a month to get to me after ordering, Chad was excellent with communication/updates throughout the process.

    The product itself is also superb; a great option for any 02-07'er looking for a quality diffuser that won't approach the outrageous Voltex price point.

    Mine went on an 07 wagon, and I can concur that some modification is needed for it to fit wagons (particularly in the tow hook area).

  2. Great Product & amazing customer Service

    Great American made product! Chad was so kind to ensure I received this diffuser in time for a show due to a few delays over the holiday season. This company has very commendable customer service, communication and quality product. Installation was easy and there was support via their YouTube video. Thanks Again Chad!! Awesome product and service

    it's not the same on the picture but on YouTube video installation its the same. I've seens on google there were tucked in and flash on the rear but I think I have to cut some so that way will tucked in and properly. but it's ok I like it.

  5. The quality tho..

    Wasn't expecting good quality for this product. When I got it I was worng the quality was awesome very premium. Would by again! Fits on 2006 Subaru wrx wagon

  6. Awesome Quality

    Posted by Matt on 25th Feb 2016

    I recieved the diffuser and as soon as I pulled it out of the box I was impressed. It has a nice textured black powder coat on it and the whole build quality of it is solid. I had a buddy help me install mine, which id recommend too. Overall the install went well, just one small little problem. I emailed Chad about the problem and he replied almost immediately and with a bit of tweaking it was sorted in minutes. I even emailed Chad before my diffuser got shipped and he'd reply in detail about where it is and how it's going. The next day I pulled into work a guy was asking me where I got it from. He's now looking on the website. 5 star product and great customer service

  7. Quality diffuser.

    Posted by Jarrod B. on 26th Dec 2015

    I was very pleased with the quality of the diffuser. All hardware included with a install guide video on YouTube made installation fairly easy. Looks amazing and aggressive!

  8. well made

    Posted by aaron smith on 25th Dec 2015

    The diffuser was very well built. It would have been nice if it was a one piece design. It was sorta hard to get the smaller piece to match the bigger one but other that i love it. Definitely recommend for anyone that wants a nice diffuser but not pay am arm and a leg

  9. very stylish

    Posted by Nikolaki on 28th May 2015

    Overall happy. A lot more than "some assembly." i also got it to fit with a non tilted exhaust, such as cobb. Looks awesome and very durable. Very rigid and sits nice once you find its sweet spot. Took about 1.5 hours to line it up and secure it fully, alone. Someone to hold it would make it Way easier. I would buy this again.
