We plan to have a camera car at the track this weekend to get some video. It should provide a great opportunity to get actual exhaust sounds at high rpms from a nearby car instead of the "drive-by" shots.

Stay "tuned"

Initial impressions on the short trip are:

1. Sound. Of course, it sounds much better. In particular, for me, the sub 2K rpm sound is pretty amazingly different. It is like James Earl Jones is talking - very broad and wide bass tones at idle and just above - almost like the difference between a Bose stereo system and a clock radio. I didn't get too much into the high rpms, and was inside the car, but it is a much "healthier" sound for sure, but not obnoxious sounding.

2. Weight. I can definitely tell the weight reduction in the rear of the car. Even on the streets, the car feels slightly more mid-engine and more lively. I hadn't really thought about this aspect too much, but dropping ~25 lbs at the tail end really reduced the rear moment of inertia. This combined with the rear wheel steer was noticeable to me. Will be interesting to see the feel on the track.

3. Shifting (MT). Perhaps the biggest improvement I noticed so far is the increased throttle response, especially when shifting. Without the GPF and with the high flow cats, the throttle really responds much better. When doing a no-lift-shift, the throttle really picks up the flywheel quicker and there is less surge. I have data from the track and will do some comparisons to see if it is more than just a hearing thing and if there is really a performance improvement for manual shifting. But, initially, it sure feels like it.

4. Lifting (MT). Another thing I am noticing is when I lift of throttle in say 3rd gear, I am feeling less slowdown (engine braking feeling). The car seems to want to coast better rather than having the nose dip slightly and slow down. It is somewhat subtle, but that's the feeling I get. For track, not sure exactly if this is a positive as lifting alone can be a nice/easy way to get a little weight transfer.

5. High RPMs. I did a few 9K shifts from 1st to 2nd (after driving about 10 miles, so the tires were a little warmed up). With the increased performance and lighter rear, I did notice a little torque kick out of the rear of the car that I had not noticed before. Again, I'll try to do an objective performance review at the track this weekend.

Overall, super happy with it, especially with the low rpm sound. I got several thumbs up from people on street corners, and the exhaust (from the inside of the car) doesn't have the over-the-top obnoxious sound that my GT4 had.

Also, good luck if those are HJS cats. I killed mine in my 981 GT4 in about 4 track days and went back to stock headers after several others did the same.

Anyway, sorry for the negative BS I hope it all works perfectly and I can copy your setup at some point. Thanks for blazing the mod trail on the 992.

I will have pics this weekend at the track.

Are you running your Cup 2 "R"s this weekend?

I'll let you know how the cats hold up.

Will be getting MCS suspension very soon too from Jamie.

And the best German cats. 911 has better packaging.

Ray don’t you have the option for a cat bypass? You don’t have to run a tune, the cel is benign.

Also, Dundon has another “enhancement” in the works…

But next up is MCS and then aero…

I haven't bothered with race headers etc on high power and torque NA cars because the gains without a tune are minimal. Moreover, when I speak to people in that part of the aftermarket world and you start asking about who did the the gas flow design and what difference did it make to inertial and wave scavenging they usually run a mile. At that price point I'd expect answers not just a dyno plot.

Dunno, maybe these guys are different. At that price point I'd expect them to be.

For the record my RS makes 529HP at the crank and around 460HP at the wheels - completely stock with standard exhaust. The implication being, with the GT3 you should be able to unlock similar numbers with just a tune.
