Supersprint Headers VS Euro Headers
Superspint Stepped headers V1 are considered the one that make the most HP for our cars. Does anybody know if it worths making the transition from Euro Headers to SSSV1 Headers?
My mechanic mentions that Euro headers is the only thing I will need for my car and that the gains will be very small if I go to SSV1 stepped headers. Other threads mention a lot of HP gains but from US headers. Also can SSV1 stepped headers work with stock mufflers? What is the expected HP gain with the SSV1 stepped headers with a custom tune? |

If I had to do it all over again it will be the last modification in my to do list. It really worths doing it only if you had to switch off from US headers... The real restriction point in Euro cars is the muffler/ back boxes as our header is a piece of art. When switching to rpi and dyno the car the gains recorded were almost 10hp!!!! |

It depends on whether you have an alpha-n tune (and have access to a dyno tuner), or if you plan to stick with a MAF-based tune. It also depends on how much money you're spending.
It's true that SS V1 makes good power over stock - somewhere around 35 hp on Euro, and 50 hp on North American cars according to vendor dynos. With FI the gains are higher. My G-Power supercharger setup is rated at 450 crank hp on a Euro car, but it's putting out closer to 500 hp with SS V1 headers/s-pipe based on my dynos on a 120k mile car. ESS wouldn't tune my car for stepped headers, so if you want to go FI / carbon airbox, you will need a custom tune to extract the power. Paying full MSRP for new SS V1 stepped headers + catted s-pipe + dyno tune, when you already have the Euro setup, isn't worth the extra power IMHO unless you're trying to squeeze everything out of this motor. Your money would be better spent on an aftermarket s-pipe... either Supersprint catted, used DKF, or some sort of custom straight pipes with resonators or cats welded in. Your Euro s-pipe is worth decent money.

Can confirm, I just asked them about this a couple days ago. Their response:
"You actually can't run stepped headers on the MSS70. The O2 feedback is completely whack on those." Of course I realized this after buying their tune and some stepped headers

The reason I have second thoughts about what you and my mechanic told me, is the email I received from the the tuner, I plan to tune the car. Here is our discussion: Me: What gains on Horsepower should I expect after the tuning? Answer: They make 280 stock on our dyno. With intake and tuning they are about 320. With a free flowing exhaust they are in the 330 range. With headers and a very free flowing exhaust they are 340-350. Me: From your experience can you please suggest me any headers and exhaust that produce these numbers? My mechanic say due the fact that the European cars have more free flow headers the change of them will not do any significant difference. Answer: If it is for a street car the Euro are ok. If sound is not an issue, our headers or the SS stepped v1 will flow more air and thus do make more power. Quite a bit more in fact. So I was thinking now that I will do the csl airbox and the tune to put also the headers to avoid the future tuning again if it makes also sense from power gain perspective and you don't get 5 hp. What do you think it worths the money? |

I have seen some dyno graphs after installing the SSV1 headers and they power gains are important. With the tune and the airbox do you think is good time to put the headers ? The get 35 hp that you mention from the SSV1 versus the Euro headers, requires to change also the s-pipe and the x-pipe and the mufflers? Can you install the SSV1 headers and keep the rest stock s-pipe and x-pipe? ESS will not be the tuner of my car but thank you for the info it is another reason to look elsewhere. |

The O2 sensors are in different locations from stock, and this affects readings which are used to control fuel trims. When I added stepped headers to my ESS supercharged car, I actually lost a bit of top-end power because the tune was optimized for US-spec headers. Of course with a retune, I gained all the power back and then some. A Z4M can absolutely be tuned to run stepped headers. ESS makes a great product and their tuning is spot on for US and Euro headers. However, when deviating outside the kit's specs, ESS doesn't like to support customization of the tune to accommodate things like stepped headers. Quote:

Again, they make a great kit, but don't seem too interested in deviating far from the standard specs.

ESS is correct about the O2 sensor location. It just requires additional tuning. The power gains are very real. Another option is the CPI stepped headers, which have given me great results.

Do you think i can gain power by replacing the S pipe, xpipe and muffler to a 3 inch setup up from 2.25 stock even with euro headers ? |

I'm not sure what to think about ESS at this point, both from what they say about stepped headers, and also 'sport button memory' which they also said wasn't available on this platform. Other tuners don't seem to have a problem getting those things done. Even if I can find a way around the CEL, I have a sinking feeling that the ESS tune won't be making as much power in this application as some of the TTFS examples I've seen, as it's optimized for euro headers Sorry for theadjacking OP I'll shut up now

Also how you differentiate SSV1 from not SSV2? Because on their website I can not understand which is the right one... Do you know also if those headers are the same also for the M3's? Quote:

I'm running Euro headers, DKF S-pipe, OEM X-pipe, and RDSport exhaust. All the O2 connections as well as the EGT were EXTREMELY simple due to DKF making it simple for anyone to do it (shoutout to Pokeybritches for the DKF!). However, I do have a CEL which is no big deal (sometimes it doesn't let me sleep at night, why lie). My point is; consider leaving the SS headers out of the picture if it doesn't give you much a HP gain over the Euro headers, it's not worth the headache IMO. As for tuning, I'll probably go with TTFS

Ross thanks for your answer. Do you have done a dyno with your setup? One silly question what is CEL? I have never read on the forum anyone to go with TTFS with his Z4M. Do you have any feedback about TTFS? Thank you again. |

The V1 header is slip-fit over the SuperSprint section 1 (no flange at all). |

http://www.zpost.com/forums/showthread.php?t=785645 You can see that SSV1 makes significantly more power in the top end when compared to the euro headers. There are also a lot of people on this forum saying that the SSV1 headers don't fit on the Z4M. Mine fit fine (coupled with new motor mounts), but do vibrate against the transmission cross member very slightly under certain conditions. |

I have the #043901 SS V2 regular (Non-stepped) headers in storage right now waiting to be installed with Euro cats once Spring comes around... Will revise my Epic Alpha N tune to run the catless headers.
