• 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.

        Much better for sure especially the price...Nice polished finish but I am surprised there is no HPF logo on the tips..If I had the exhaust I would want to flaunt the HPF logo BIGTIME

        Wow, that price is pretty insane for the HPF product. That exhaust looks very very good. One thing I noticed over the last year with this BB is that the N54 section gets by far the most amount of traffic. Every time I come here, there's more people browsing this section than any other one. And I always thought, why aren't there more products coming out for this platform. Did tuners think that we've hit the ceiling with this car? And today the big guys come out and release a hot sexy exhaust that I might actually get. Good on ya HPF, now have Falon post the next update.

        Oh yes, sound clip pretty please!!!

        Well to be honest its reached it climax and the next big thing will be single turbo upgrades..But I have to admit this exhaust with pricing is going to be a hit...They MUST put a logo on the burnt tips!

        It's just natural. N54 owners want to tune. The other BMW motors were naturally aspirated for the most part and also already had established forums. Growth N54 first makes sense and it is the bread and butter so to speak. Not to mention e90post pushes a lot of people to us with the whole Shiv/BMS discord that was and still is badly managed.

        So, was the original basically straight pipes? And now they are resonated?

        I guess the opinions on this topic will vary. There are a bunch of people here that will most likely argue that the N54 hasn't even began to scratch the surface, even with the dual turbo setup. Now I also remember an HFP representative state they are interested in developing an upgrade for the guys who want to stay with the dual turbos. Wonder if that's still on the table and wouldn't mind somebody chiming in on that from their HQ.

        Looks great, but the burned tips are not. Leave that for the Sport Compact crowd.

        Luckily that have other tips available on their site.

        Looks very, very nice, but I would still take the non-resonated exhaust. Click here to enlarge Of course this would probably be a bit better for daily driving. Is there a comparison between the non-resonated to this one? as far as how loud it is?

        very nice as well! Price is also not that bad either, priced right in the middle between AE and Vanguard.. my only thing is, with all these pictures, I can barely see any of the quality welds and all that stuff due to the white background and the flash with the polished piping...I cant see $#@!! Change it to black and it will really make that exhaust 'pop' and highlight the amazing work Click here to enlarge

        Is it just my monitor or are those pics really bright and washed out?
