Yes those were are consistent numbers the end consumer can expect.. After repeated independent testing..
We also had many Peak runs of well over 35 Rwhp gains as well..
But we safely put our 34 Peak RHWP out there for the Dynojet SAE Corrected # , as tested by D Sport magazine.

Any who.. They are all making similar power and I doubt one will edge out more than another at a 1/4 mile track / trap speed.
Happy Modding

yeah the JOE Z will bring at least 30. You cant really re invent the wheel either the exhaust flows or it dos not flow. 5 rcfs on the same dyno will bring 5 different numbers with the same mods. JOE Z is by Far the best option.
I will have less than $6000 in my entire Exhaust with my PPE headers and Joe Z exhaust not just a catback for the same money and im having my headers installed by Lexus tech.

I can honestly say that you will not be sorry. I went for the Joe Z because I just couldn't justify the extra money for the other, I could have easily afforded it but I have an issue with a purchase where I feel I am throwing money away. I am not saying the other exhaust is not worth the money, just not to me.
After I installed the exhaust I knew I made the right decision. It sounds great, but I can still use my hands free without annoyance and the cabin is still quiet while highway cruising. My mpg went up almost 2 mpg on the highway as well, not sure if it was all exhaust or the car finally breaking in but my average on the hwy is 26.8 mpg @ an average cruising speed of 75 mph and I NEVER run it in dedicated eco, it lives in normal on long trips.
Great exhaust, great customer service, fast shipping and more than fair price for what you receive. Installation was simple, quick and fit was excellent. Only thing I can "complain" about is I wish all new bolts were provided rather than reusing two of the factory ones, small gripe but it's just my preference.

From the manifold to X-pipe connections
There is no need to replace them with identical new parts..
Here's a pic during our extensive R&D sometime last year..

The stock system is very restrictive, any aftermarket complete exhaust system will yield 30+ RWHP. As for the GTHaus exhaust system, the gain is about 37 RWHP, the other 9 RWHP is from my Rotora carbon ceramic brake system, dyno sheet below. I also dyno it again on the dynojet and got 413 RWHP.
Perhaps focus less on peak hp and peak torque also. Optimization of area under the curve might be more satisfying to most on here concerned about straight line acceleration in the 0 - 60 or 100 range.
How does Joe Z stack up as far as area under torque curve would be the relevant question.

I have the full Meisterschaft system ($4500) and love it, but if someone wants to buy it so that it's quiet sounding like stock when closed, this isn't the system for you. It's still louder than stock when fully closed, but fully open just sounds SO SICK..........I drive with it open most of the time unless I'm taking a phone call or using cruise control.
Another option would be to buy just the Q-tip valves and have a muffler shop install them for much less. HP/LB FT won't be as much, but it will give you flexibility in tuning your sound (also remove your resonators).

Is the exhaust available in catback only? Reason I am asking is because it look as though in the RCF installation video you put on a full exhaust for the RCF. Thanks

My experience
I got my RCF in december and got the PTS Joe Z in january, couldn't be happier about the change, I like the sound and quality of the system. Had a chance to listen to the GT-Haus, it sounds great but I wouldn't choose it for daily driving. Unfortunately I will posting my Joe Z for sale since I might be trading the car for something else..SUV
