That's me! They took the pics at HKS and took the rear WALD apron off since the tips were too short for the spoiler. I ended up using some HKS Titanium tip extensions (thanks HKS!) to even it out so my car doesn't even look that that anymore. The sound of it is GREAT!!! The second resevoir is a sound deadner (resonator) since the first attempt we made turned out WAY too loud.

HP Gain + Noise Level
OMG 
, just called HKS-USA for further information on their "Hi-Power Exhaust System for Lexus GS300/GS350." To my surprise, they have no idea of how many horespower it would gain nor the noise level.
Thanks to Carson Toyota, I have found the answers.
The kit will increase about 8 to 10 HP on WHEELS; and the noise level would be a pinch louder than the Infiniti G35.
Hope this will solve some of our curiosity
with "HKS' Hi-Power Exhaust System" for our toys !!!
Again, thank you for the information Carson Toyota Staffs.

I wonder the same thing too... How loud is a pitch louder than G35? To me G35's exhaust sounds very tempting and also very close to my tolerance.
I don’t think a sound clip can provide any good indication to the actual sound of exhaust. It’s very weak reference in terms of dB level.
I like the TRD exhaust but too bad there is nothing to buy from them for the 3GS.

Plan to install it this weekend, if time permits.
I'll report back then.
All I can say now is that the exhaust looks awsome in person.
I stood there at Carson Toyota arguing with myself... I typically don't like large tips. But the quality construction and materials made my decision to purchase it, not to mention the great price.

Hey guys, I just wanted to post up and show some new pics we just received of the new HKS Hi Power Exhaust for the 3rd gen GS.
These also are on GB right now here https://www.clublexus.com/forums/sho...d.php?t=276984

2007 California Vehicle Code: A sound level of 95 dbA or less is legal.
I wonder why doesn't Carson Lexus or HKS release the dbA number??
