• New HPF 335i EXHAUST PROTOTYPE - 40 pounds lighter than stock, adjustable titanium tips, $1595

      Here are some pictures of our "NEW" single 3.5" exhaust "with Resonator" for the BMW 335i. Our previous versions did not include the resonator and many people that have our Gen 1 versions wanted it to be a little quieter. People also wanted a better price. Not only did we accomplish both of these goals, we also kept the extremely high quality as you can see from the pictures below. We offer both flame style and polished titanium tips.

      This is still just a prototype and it will be three months for our first production batch. If anyone has any questions about these or would like to find out more information, please PM me or my staff.

      A Staggering 40 lbs weight savings (OEM Exhaust = 75 lbs, HPF Exhaust = 35 lbs)
      100% 304 Stainless Steel 3.5" Exhaust
      Stainless Steel Resonator
      3.5" Fully Adjustable Titanium Tips
      Super strong stainless V-Band flanges For easy installation and adjustment along with leak free operation
      Fully Polished
      100% Mandrel Bends
      Flex Section
      Rubber Isolated Mounts
      Minimal exhaust movement due to triangular mounting method
      Aggressive Styling with Large 3.5" Tips
      Exotic Exhaust Note

      The final production version will be $1595.

        So, are we still sure that exhaust past the downpipes doesn't do much for perfromance? I really do like the looks of it, and between this exhaust and a lightweight battery you could save 60 pounds! That seems like a lot of weight. With the reduction in weight and some? HP gain, it might be worth it. I guess.

        You would feel 100 lbs difference. I sure did with my GTI when I took out the back seats and spare.

        I was under the impression that N54 and N55 mid and rear sections are interchangeable, will this also fit an N55 335i?And, more relevant to me, will you make an exhaust for the 135i?

        N55 and N54 exhausts are exactly the same. Only difference is I to XI models, OEM exhausts will bolt right up, where as aftermarkets usually wont.

        This should fit on an N55 335 car with no issues...Im kinda actually hoping someone around here will get it, Im dying to see how it sounds as I LOVE the exhaust note of the N55 Click here to enlarge

        No they are blow out to hell.

        I should throw them in Lightroom and drop the exposure.
