We have already DYNO'd the 2GR-FSE motor on the 2IS & 4GS platforms..
For the IS350 / GS350 this exhaust lay out consisently put down 8-10 rwhp...
Same applies to the Intake... 4-5 rwhp with stock filter. (Original Design Since 2006)
Eventually, we will get this model on the Dyno as well.. But for sure we will only dyno with stock vs modified parts... (in other words no other brand filters, etc.)
Results will be the same..
Thanks

I had an IS 350 Sport new in 2006 and had your intake tube with HKS filter and Tanabe exhaust. I wasn't sure if this new exhaust used the same muffler system as your 2IS system. Thanks for the info.

The exhaust tone is slightly up but still most would not notice it. I quite like it since it's very close to stock. You'll notice it from mid to high end of the rev range. I wonder if the JoeZ exhaust having lose the secondary cats and have different resonators that the sound will be unbearably loud and drone.
