Again, you're more than welcome to make the trip up to tour our facility, meet our engineers and tuner. I just went out into the shop and shot this F12 on the dyno here:


We're currently dialing in a tune for it. Our tuner means business, has decades of experience, and lives this stuff every day. If you browse our site, yes, some of the old products are not marketed the best with not the best media. We are working overtime to improve the quality and quantity of our products, be transparent, and work with the community to make everyone happy. I'll stop trying to convince you, but the door is always open here and feel free to PM me with any questions you may have to shed any doubts.

Dude I was right there when they did the dyno pulls, what do you think that they forged the dyno sheets and just handed me that and said thanks for your business? You're crazy dude, these guys are way too professional to handle business that way. It sounds like someone is a little upset with their results, who knows. I'm beyond content with my product and my numbers, I know what I put down, if you don't want to believe it then so be it, no need to bash a company because you refuse to believe. But have fun man, good luck and have fun on being pessimistic on your build, I'll make sure to strive to have only the best products and tuning on my car with Fabspeed.

This is not cool man. First your Dinan bashing on the Dinan s3 thread and now trying to start something with fabspeed...

Take a look at their product listings and claimed dyno results for yourself. They quote like 2-3 different conflicting results on many cars. That is not bashing, it is pointing out the obvious. Either they're really sloppy recording and printing results, or they are full of BS. I find all the conflicts terribly suspicious.

BTW...don't hold your breath awaiting those promised Dinan independent testing results. The whole modification/tuning industry is full of wild claims that are seldom independently verified, and when they are, their measurable results don't live up to the hype. Google some of Dinan's (very few) prior instrumented road tests. The statistical measurements don't jive with their horsepower claims.

Will be refreshing when more customers/magazines actually hold tuners accountable for their wild claims. Believe me, I'm rooting for the tuners results to be true, but believe they are grossly inflated.

BTW...I'll give Dinan credit for one thing, at least they are no longer taking credit for results partially attributable to a manufacturers own under-rating of select model's output. That was a very common tuner trick as posting a larger delta attracts more buyer attention.

Yes, operators of dynos can easily manipulate results via multiple factors including drivetrain loss assumptions, etc. Take their claimed results with a grain of salt. If you believe what they are telling you without unbiased independent verification, then you are a sap ripe for another raping with their Stage 2 mods.

I'm not doubting you got some lesser improvement, just not 30/30 on an untuned but sport catted N55. For a dose of reality, even the S55 with a sport catted downpipe is only showing 21/23 on a competitor's site.

We can craft anything out metal that you desire and tune it appropriately. You're close enough to where we can make this happen, shoot me a PM and let's do it!
Is your dp compatible for all N55 models (1/3/X/Z) or specific to the m235i?

We have verified fitment in-house on M235i and 335i. Our downpipes should fit on other N55 equipped vehicles. We do know there are two flange types for the 335i and 435i, depending on the wastegate style of the turbo. Pre 08/2013, a smaller flange is utilized, and we created a separate downpipe for those vehicles as noted on our site.

I'll make a review too after the install this weekend. I'm getting the new and revised version so we'll see. My expectations are very high with this catted DP.

I also got the revised version and I can guarantee you that you will not be disappointed with this product. I've had it for several weeks now and I'm still not bored of it and happy with the way the car performs.

Just got my Fabspeed Sport Catted DP on and OMG is it love paired up with AFE Scorcher module and MPE! Car is beast now and 60-120 pulls are like nothing with 3rd gear searching for traction lol... Cant really tell any difference vs the first dp that had a CEL issue but this one seems slightly different in regards to harmonics but again I'm about 200 miles in with NO CEL and all is pure love with the purchase and FABSPEED! Ill post up a review and videos sometime this weekend if anyone is interested!

glad to hear everything worked out for you. I'm at almost 3000 miles with my m235, 2500 miles of which I had the Fabspeed DP on it. No CEL, no complaints, and nothing but respect and pleasure of the product.

Smell? I have not smelled anything different from when the car was stock and after I installed the downpipe and Fabspeed's new Axleback/Muffler Delete Exhaust. (Check that out btw, it's awesome).
