Agency Power 2015-2017 BMW X5M X6M F85 F86 Stainless Steel Catted Exhaust Downpipes - AP-F86X6M-172
Description: AP 2015+ BMW X5M/X6M F85/F86 Stainless Steel Catted 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 we 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.
