    Giving this a five star review because the order was shipped fast project was as described, however, FedEx didn’t deliver the package until after it circled the south east of the United States for a week past the delivery date. My issue was with FedEx on this, not with the seller as the seller shipped exactly when they said they would. Would do business with again like I said issue was with FedEx not seller

    The seller was great and shipped my resonators out fast. I returned them because of the quality of the welds and the pictures that Borla uses is not true representation of what they look like.

  • This review WILL make your desicion for you.

    I'm not the smartest guy in the world but working in the automotive business and being ASE certified until December of last year I found myself asking...How is Injen's intakes "TUNED". It has no mini computer or wires hooked to it. I had a cheap intake installed and then installed this one. There is definitely a difference. While on a stock car it's not always astronomical, if you have mods and a factory intake, prepare to witness your car be reborn. You can not post links in reviews but just go Google How does Injen tune their intakes? to se how Injen "MR technologies" "TUNES" there intakes. Injen is the way to go! I haven't seen any other companies mentioning things like Bernoulli's Theorem or the like.
