  1. nice very nice 5 Star Review

    Posted by on 24th Mar 2016

    Sounds loud

  2. love it 5 Star Review

    Posted by on 14th Mar 2016

    Part was easy to install
    Not much of a car guy mechanic wise, but very easy to do
    Has a loud sound and couldn't be any happier

  3. Perfect product for a low price 5 Star Review

    Posted by on 19th Feb 2016

    I purchased this for my 16 Fiesta ST. Pretty easy to install and the only part that was difficult is the tight space. If you have just an allen key it would be very difficult. I have a 1/4" socket set with allens. That made life very easy. product is great and I love it cheaper alternative for the BOV sound

  4. More Smiles, more broken necks 5 Star Review

    Posted by on 12th Feb 2016

    This thing is brilliant, it gave me exactly the aggressive noise i was looking for, to really accentuate and brandish that little turbo. Makes people second take the car every time i fly by, and the finish (red anodize) is impeccable.

  5. Nice piece I might add.... 4 Star Review

    Posted by on 19th Jan 2016

    I gave this 4 stars due to nothing being a five star product until it is put through the elements....time and abuse. But install was easy. Get a long Allen head socket with the ball head to make it easier to access the bolts. A hoist definitely makes it easier for sure.The sound is not super loud or annoying. Just enough psssshh! Good job boomba!

  6. Very Satisfied 5 Star Review

    Posted by on 8th Nov 2015

    My order was shipped the next day and arrived in 5 days. Installation was very simple and the sound is great!

  7. STOP READING AND BUY IT!!!! 5 Star Review

    Posted by on 5th Oct 2015

    while looking for a first mod for my ST i came across the boomba adapter and decided it would be my first purchase. BEST DECISION EVER!

    i cant stop listening to the sound and the install took less than 30 minutes. i spent more time jacking the car up than actually installing the part. so like the title says, stop reading and buy this now!!!!

  8. I was smiling... 5 Star Review

    Posted by on 15th Sep 2015

    Since my first day driving my 2015 Fiesta ST I have been smiling non stop. Then, I stumbled upon Boomba Racing's site and watched some videos on YouTube. Instantly I placed an order for the Red anodized BOV adapter. The shipment was quick, packaging great, and the instillation was a breeze! Now I've gone from smiling while driving the Fiesta, to giggling like a little girl with every shift and bump of the throttle! The decals included look good in the quarter windows too! Now I can't wait to get ahold of that motor mount! Next order to be placed soon, thanks Boomba!

  10. Vrrroooooom...TSSSSSSSSSS 5 Star Review

    Posted by on 3rd Aug 2015

    High quality part, easy to install yourself, works exactly as advertised, and shipping/customer service are top notch. I will definitely be a lifelong customer of Boomba Racing.

    PS for anyone concerned about exactly what parts they should use for install here's what I did:

    Jack and Jack stand
    3/8th in ratchet
    Universal/swivel/wobble joint
    5mm hex bit
