HPF 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.

904/21/2013335iInstallation want quite flawless on my E90, one mount needed some altering, and there weren't any instructions. But, I could not possibly be any happier! The sound is perfect, loud and the perfect tone. I am finally able to hear the turbos, and you would be surprised how much more I can feel them with just a bolt on. There is no better option for an exhaust than the hpf set up.

1004/09/2013335Xigreat fitment + top quality built + amazing sound = :)
803/10/2013335iBought and installed the exhaust about 4 months ago. The build quality is excellent and the HPF team are very helpful when I had a question. Installation was very easy and seamless except for two minor things. First, getting the front section to mate with the downpipes was challenging, I ended up having to pry the two tubes apart about 1/4" to get it to fit with the downpipes. Second, I've messed with the location of the tips about a million times but they still hang down too low for my taste. The sound is awesome and very aggressive, lots of pops and burbles when you get off the gas. My only wish was that it was just a few db quieter, there are a few rpm ranges where the resonance rattles your brain. Tons of drone most everywhere too. When you buy this exhaust please realize that you're pretty much getting a straight pipe, it's going to be LOUD...good but loud.
1006/16/2012335iHi, very good exhaust, it's very easily to set up, it's very beautiful, and the sound is really beautiful,an unbeatable value for money. Thank you very much HPF, it's only happiness !!!!! Bye
