  3. Agency Power BMW X5M, X6M & xDrive 50i (09-12) Downpipes

    The BMW X6M and X5M SUV is a powerful vehicle with BMW’s V8 twin turbo engine. Because of the high horsepower and torque this vehicle produces, Agency Power set out to improve the performance with a set of race downpipes. The factory restrictive catted downpipes choke up the factory turbochargers. These race downpipes feature a high flow resonator to keep the sound down while improving power.

    Constructed of high quality 304 stainless, these exhaust parts are designed to last. Thick flanges, precision engineering and built-in flex joints ensure your Agency Power downpipes are the perfect fit for your BMW X6M.

    The tested downpipes produced 25hp and 12ft lbs of torque to the wheels and produced no check engine lights.

    Fits: BMW X5M, X6M and X5/X6 xDrive 50i cars.

  4. Agency Power BMW 1 Series 135i & 3-Series 335i (N55) (10-12) Downpipes

    Agency Power’s downpipes are designed to improve your turbo charged vehicles performance. These pipes are made from polished 304 stainless steel. The N55 engine runs a single turbo setup as the predecessor to the N54 twin turbo engine. It connects to the single turbo like stock with a V-Band clamp and then connects to the section 1 mid pipes.

    The downpipe has an inside diameter of 4″ with 2.5″ flanges. The larger diameter design will improve exhaust flow, keep boost pressure up and provide improved throttle response. This down pipe eliminates the catalytic converter. With the reduced back pressure, the exhaust will have a slightly different tone and the overall driving performance will be noticed.

    The down pipe has two oxygen sensor bungs so you can retain the factory inputs. An ECU Flash is recommended to maximize the performance of your car. Thick flanges, sturdy hangers and increased flow make these down pipes a must have for all 135i and 335i enthusiasts with the single turbo N55 cars.

  5. Agency Power BMW X5M/X6M (F85/F86) 4.4L V8 Turbo (15-17) High Flow Cat Downpipes

    One of the best modifications you can do to the turbocharged BMW engines is a performance exhaust system and downpipes. Improving the exhaust flow and reducing restriction can yield gains of up to 40hp over stock. The BMW X5M and X6M F85 with it’s 4.4L V8 twin turbocharged engine is very susceptible to modifications increasing the menacing 575 horsepower.

    Similar to other BMW’s engines they have built downpipes for like the 335I N54 N55, the 6 cylinder 3.0L twin turbo BMW M4, and even the similar BMW M5 F10, these engines are easy to gain a boat load of horsepower with simple bolt on modifications. As Agency Power has done before on many other vehicles, high flow cat downpipes off the turbocharger are one of the biggest boosts in performance.As an OEM replacement to the factory catted downpipes, these full 304 stainless steel downpipe are precision TIG welded to provide the turbocharger exhaust side with the least restriction possible on the exhaust system.

    Utilizing high flow 300 CEL GESi catalytic converters, these new downpipes keep you emission friendly while improving performance. Typically the difference between Race and catted downpipes is about 5-10 horsepower difference. The high flow cat downpipes reduce backpressure to help the turbos spool up quicker in-between shifts while giving a strong pull through the RPMs to the top of the power curve. Catted downpipes do give a more audible sound to your 4.4L V8 without having to change the full exhaust system.

    Agency Power has found that many of the new exhausts on BMW’s flow quite well and the downpipe’s alone are the best upgrade possible. However if you do add an exhaust, these are made modular to work with the OEM or OEM style fitting exhaust.Even though the downpipes have factory located O2 sensor bungs, and high flow catalytic converters, a check engine light code could be possible because of the sensitivity of new vehicle emission systems. An ECU Tune is recommended to elimiate any possibility of a check engine light and maximize the performance of your 4.4L V8 Turbo. If you are looking for an instant boost in horsepower and performance, the Agency Power downpipes for your X5M or X6M is recommeded.
