In other news about exhausts for our cars....Apexi exhaust will NOT fit your car if you have the TVD. I believe they are working to correct it, but it could be a bit of a wait. After seeing the numbers from Joe Z, I've made my decision. I also like to keep aftermarket parts from the same company (most of the time) due to dyno testing. They make sure their parts perform perfectly with one another...I'm referring to a Joe Z intake paired with their exhausts and not throwing up CEL's. Now only if the guys creating headers can giddy up quickly I'll be G2G.
EDIT- The price is 2190$ for the APEXI.
When I got the PTS - JoeZ Series exhaust on my RCF I'm so glad that PTS & Joe Z took their time to make sure they engineered their exhaust system to work on both TVD & Non TVD variants!!!

We saw similar outcomes from stock IS F's back in 2008.
We are also all dynoing brand new cars...
I will say the TVD unit is massive, bulkier and weighs more then the standard Torsen unit.. As disclosed by Lexus themselves.. ( added xx lbs to the car)
The housing itself also favors the left side...!!!
The axle is shorter on the Drivers side and longer on the Passenger side..

If anyone has a Joe Z, put up a video so we can hear it.
I spoke with ISS Forged and the exhaust system should be available very soon. They are using 321 stainless which is lighter than 304 used on other systems. I was told hp gains were 29 wheel hp and torque increase came in at 60lb/ft to the wheels. That is much more torque than I have seen any other system make. The price quoted was $4,995 plus shipping.
BTW, I was not planning to purchase this system. I have been calling around to gather info on as many systems out now or in the near future. This is only meant to share info with anyone scrolling through the thread.

I paid less than $2800 for my ISF ISS Forged QES exhaust. I love how they doubled the price for RCF customers haha.
