Do88 Plenum and Y-pipe
Has anyone had experience with the do88 plenum & y-pipe vs IPD plenum & y-pipe? Wondering if there's a big difference between them and IPD. I can't find too much info on the 991 TT/S application besides their claims and dyno charts.

From what I've been told by experienced tuners on my last Turbo, the IPD plenum doesn't any significant gain. I don't have any actual feedback on the Y-Pipe, but take my advice, these cars are extremely fast. You'll never use all of its power stock.
But if you want to venture for a more competent increase in HP and performance try a tune by a qualified tech. We have several advertisers right here on this board. Sam by Design seems to be very popular. Otherwise put good investment in your tires and perhaps an exhaust upgrade along with driver's education. Hope this helps.

I think all this plenum stuff is quite a like hocus-pocus for cars with stock turbos. But at least do88 says they plenum is better, than IPD. What I know exactly - it's much cheaper

At moment my car is in service to install all that stuff below. But because I ordered intercoolers too, I can't tell how much plenum and Y pipe helps, neither I have no data for IPD comparison.

I would have to pull the dyno sheets but I believe the IPD plenum & y-pipe added about 15 whp, never compared anything else because IPD is what everyone I talked to recommend

With or without a tune? That comes out to a little over $130 per 1HP. Given the small impact with stock turbos, I have to believe the less expensive DO88 pieces can’t do any worse. Of course they don’t have the dimples...;-(

Given that Do88 BigPack package is much cheaper overall than the competition, I am considering doing everything altogether. Why is buying car stuff so addictive????

Other way to look at it is that Porsche did a damn good job with the hardware from the factory. Obviously like most automakers they are conservative in tuning from the factory just because of the varied operating environments the cars are driven in such as altitude, octane available, emissions and gas mileage, competitive driving, etc. They strive for the balance between longevity and performance. I can see where a more aggressive tune coupled with more efficient flow between intake and exhaust..as well as reduced intake temperature with larger intercoolers can be part of a systematic upgrade. Have to believe the y pipes and plenums alone however don't give you much in terms of bang for the buck over OEM.

Speak to Ken at Nine Excellence in the UK. He has fitted the full do88 big pack to a 991.2 turbo S with great results. 0-60mph in 2.2s, 0-100mph in 4.9s, including other mods

It was quick, I ordered those intercoolers, Y pipe and plenum last week from www.Do88.se and now they are installed. Only bad thing is - there is still snow everywhere and I can't use those extra horses.
All parts fits correctly and were good quality. As you see, intercoolers, hoses, plenum and Y pipe all are larger than stock.

Honestly at the Lower price point of this system there is little downside if you are into the engine compartment that far for ECU removal or cooler upgrade to replace the Y and plenum as well. The fact that there is more of a divider in these units for airflow vs. hitting a flat wall in the stock unit seems like air should flow somewhat better. Not sure if larger diameter is better or worse for low end response.
