One thing I have learned for certain; time to ditch the side mufflers on my .2. Obviously Porsche has made that clear. Now to decide on yhe set-up.

@stout is the exhaust in the speedster louder, lower or same as .2gt3/gt3 RS?

is the delta between a speedster and GT3 manual / touring really worth it?

From Porsche's point of view, yes. It will certainly help them to pay the 535 MÇ fine for the Dieselgate:

I want this car - I love my Touring but good golly. I have wanted a Speedster desperately ever since the movie, The Freshman in 1990.

While many Rennlisters have reported good results with side muffler bypasses, I don't think it's quite a fair inference to make that because the Speedster has no side mufflers, we should delete them from our .2 GT3/RS cars because Porsche has decided they are redundant or useless going forward.

To me it sounds like the entire exhaust system (and ITB intakes) has been redesigned as a system. I read somewhere that the new central (only) muffler has internal flaps and other electronically controlled internal functions to optimize the exhaust sound and (now broader) power/torque across the rev range. The current vacuum controlled exhaust valves are replaced by functions in this new fancy muffler.

So, I guess I'm saying the systems are apples and oranges. What works on one, won't necessarily provide the same result on the other...

Only you can make that determination.

Thanks for the info, stout.

also, will the mesh be a part of all US Porsche vehicles or just the speedster for now?

Def. not! Same power pretty much for double the price almost

The 911 R MSRP was much better priced in my opinion and was more limited 991 as opposed to 1900 plus

Hi thanks for the interesting review!

Are the wheels on the Agata grey Speedster in Satin Alum or normal SILVER color??

Agree in principle. However, I'm also interested in weight savings.

It seems that deleting the side mufflers (while keeping the valves) is (other than lightweight lithium battery) the best option to reduce significant weight in 991 GT cars without much of a downside. Let me know if I'm missing something.
