RSR Style slash-cut tips within the carbon fiber lined cut-outs.





Remember, all else but the exhaust is stock on the car at this point. The AWE Tuning exhaust has unlocked 58 ftlbs of torque to the wheels, equaling ~61ftlbs torque gained at the crank.






Sound wise, it’s revealing a brute tone – with perfect in-cabin sound to boot.

Stay tuned for video and sound clips…

 

I LOVE this thread

 

There are so many things in this thread that I like. Please tell me this car will end up at NJMP for track time at some point.

 

Holy **** just on an exhaust? Pair that with the GIAC flash

Have you seen European Car Magazine's review on it? http://imgur.com/a/gZZhn#0 It has a GMG exhaust so I wonder what the gains would be with AWE's exhaust!

 

omfg.... best 911 EVER.

 

Joe, are you guys planning with intercoolers? The size and dimentions of the ICs are different than your current core.

 

Correct me but it seems an increase in hp and torque at medium rpms mostly but the final outcome at high end rpm remains the same, right?

 

Hi Mike, the exhaust is bringing serious torque to the mid range – absolutely. Software may open up the top a bit. However, Porsche did a solid job of not leaving much on the table with the GT2 RS when you’re using 93 octane. Larger turbos would definitely unlock the high rpm power band, though that’s not in our immediate plans. Headers are in the plans, so we expect some activity from that upgrade as well.

I will say… The new mid range power makes for quite the driving experience.

 

Thinking about how a turbocharger system works explains it all - turbos will spool up quicker if there is less backpressure (lower restriction exhaust) so what you are seeing is the power band shifting towards the Y axis from faster spooling. The turbo max boost is still limited by the ecu tune which is why the max hp stays the same. The key though is the big gain in "Area Under the Curve" which has been discussed in a nice thread here before. This results in better off throttle punch and reduced turbo lag which is well appreciated in street/daily driving.

 

While we’re working on the street videos for the Exhaust (ok, let’s be honest, this one’s fun to test drive), here’s a glimpse into what’s next – Headers. The AWE Tuning fabrication team uses purge TIG welding when building the headers to ensure smooth, strong welds. They do this by filling the internals of the tubes with inert gas to eliminate weld burn-through to the interior. The purge welds are further hand finished for extraordinarily optimized exhaust gas flow. Take a look:







The head flanges are flycut in our CNC vertical mill to ensure a 100% flat contact surface. This eliminates the possibility of any exhaust gas leaking from this critical point. Any leaks would slow turbo spool equaling power loss.







The headers get extremely hot on the street (but you knew that), let alone on the track. That is why we use 321 grade stainless steel tubing, rather than the more common 304 grade stainless. Being more thermally stable, 321 grade stainless steel prevents deformation or cracking over time. The tube paths were kept equal in flow in our design, pre-modeled in our CFD (Computation Fluid Dynamics) software.







Stay tuned for power information on the headers, and more on the exhaust…

 

Subbed , great thread .

 

Many of you may be familiar with what the “underbelly of a beast” looks like in action. That said, who doesn’t want to see a GT2 RS heating up in action?


The header R&D is wrapping up nicely.

To come: Dyno sheets with the headers… stay tuned!

 

what happens if you put a GT2 exhaust on a TT? or does it not fit?

 

Jesus. Talk about being underated. I've had my 996tt on the same dyno with and exhaust and flash and it only put down 430whp.

 

This system is unique to the GT2 RS. The tip outlets, and tips may preclude this from fitting the TT.
