SpeedTech MAFless Y-Pipe
We just completed this 996TT Y-Pipe in a black wrinkle finish for a customer doing a MAFless set-up. It features DV vent tube delete, 2.5" legs, 75mm outlet for larger throttle body, black wrinkle powder coat and the addition of dual Tial BOV's. Contact us for pricing, if interested in something similar.

Yes. It connects to the throttle body. The type of plenum does not matter. It is made for even flow into a 75mm throttle body, although we can supply a step down silicon connector for OEM throttle bodies. I run the same pipe with IPD and the DV vent.

No, we stopped producing the short version several years ago. The shorter style just used longer silicon hose. Same effect.

Rich,
Our Y-Pipe is designed to replace the OEM unit and fits with the stock airbox. It is a very tight fit over the MAF tube. If the V-Flow has a larger diameter tube in that area, it will probably not fit. If you are running an airbox/MAF you would want to look at our conventional Y-Pipe, as the Tial BOV's would not be possible with an air box in place....of course with a MAFless set-up this all goes out the window and the clearances are a moot point, unless you are still feeding non metered air through the OEM filter and OEM plumbing.

One of the advantages is that the air filter can be moved closer to the turbo for less restriction, less plumbing and there is no need to incorporate an MAF in the mix. Additionally, there is no potential for failed MAF's in Higher flowing /high HP builds. But is does require precise tuning to get the tables right using the MAP sensor and there is no built in automatic, on the fly ECU adjustments demanded like the MAF does for the ECU. For instance, your tables may be off if you substantially changed altitude with a MAFless tune for sea level, whereas the MAF would calculate any air/fuel adjustments required automatically. I don't feel it's for everybody and we do not offer a MAFless tune. But we produce the Y-Pipe for those that want it.

It's relatively simple. Airbox out and a few bolts and hoses disconnected - that's it. It's really quick and easy...

Can you PM me a price for the Mafless y pipe without BOVs or any extra bungs for meth. I would also need the intercooler piping as I am currently still using the OEM intercoolers.
