Acoustically-Tuned Applied Kinetics, is Borla's newest technology that produces the highest available dB (decibel) levels to pump the volume while retaining clarity of sound, avoiding distortion typically found in louder exhausts. The ATAK muffler uses a multi-core straight-through design with both perforated stainless cores and ceramic material to absorb high-pitched sounds.

    Superior Construction. The Borla ATAK Cat-Back Exhaust is constructed from premium 300-series austenitic stainless steel. The included ATAK muffler features a 2.75" inlet with a dual 2.25" outlets. The System includes a pair of 4" stainless steel exhaust tips that are completed in a black chrome finish.

    Direct Bolt-On Installation. Borla engineered their Cat-Back to be a direct bolt-on upgrade replacement for your 1500's factory exhaust. There is no cutting or extra modifications required. Installation of this Borla Exhaust can be completed in about a two hours with just basic hand tools.

        3 Top Rated Questions

        if i already have these installed, can i pair it with the kooks headers?

        Will a 35" mud tire interfere with this side exit system?

        • The Borla ATAK Dual Exhaust System should work with 35" tires with the correct wheel offset and appropriate lift size.

        Is this legal in all 50 states? There is another one on the website "Borla ATAK Dual Exhaust System - Side Exit" that states its legal in all 50 states.. whats the main different aside from that this has the black tips?

        • This will be 50 state legal and the only difference would be the black tips between the two.

            Worth every penny

            At first, I was kinda worried how the system would sound. I didn’t really care for how it sounded on the comparison video on this site but figured I’d still give it a shot. The hardest part of the assembly/disassembly was getting the bolt loose behind the cat. Everything else was smooth. Great product. Love the sound, power, and the ease of installment. Also, very thankful they have the installation video. Definitely helps alot when trying to figure out what tools I need. Only takes one trip to the toolbox and not multiple lol.

            Love the deep growl

            First upgrade i made, and i believe it will be the best. Totally changed the tone of the truck. Not overly obnoxious but just the right tone for any style driving
