HPF HorsePowerFreaks BMW 335i Exhaust Systems
The HPF exhaust system is one of the highest flowing exhaust systems on the market for the BMW 335i with staggering 3.5" stainless steel piping and a 14" stainless steel high flow resonator. Simply installing the HPF exhaust and removing your factory 335i exhaust system will take 40 lbs off the weight of your car due to it's single large diameter pipe design. For those that have a wideband or want to get one, you won't need to own a welder and weld an O2 bung with this exhaust. Simply screw the wideband O2 sensor into our "pre-welded" O2 sensor bung. If you don't have a wideband don't worry, we ship the exhausts with a bung plug to seal the hole. The HPF 335i exhaust system is designed for the factory twin turbo cats all the way to our future single turbo upgrade which will be coming in the "very" near future. You won't ever need to buy another exhaust system. This exhaust will easily support the flow requirements to exceed 800rwhp. With 100% polished stainless steel and fully adjustable 3.5" titanium tips, give your 335i the look it deserves and a sound that turns heads. Think running without a muffler sounds loud? Check out the video below and see for yourself. There is minimal drone with the rubber isolated mounts and the sound is exotic.
