I bought a Borla cat back from a guy in California that he had on his car before returning it to stock for trade in. I assume he had to have car inspected but maybe not. Maybe he had connection for getting it smogged. U will prob be disappointed with the Borla axle back, I am sure u have checked out the YouTube videos of the axle back, might as well stick with stock and save ur money

It Definately has a deeper sound at start up and idle but not that much louder than stock when accelerating.. As far as drone goes I've come to the conclusion all aftermarket exhausts for ISF have some sort of drone around 2000rpm.

Rossi why don't you do the secondary cat/muffler delete? I can tell you that really wakes up the V8 and you'll save some coin. If you don't want to tamper with the stock exhaust that's a diff story. You can get the stock parts welded back on if needed. Just giving you another option. Although since you are in CA their emissions are strict. Unless you know somebody that can pass you. I know that in NY they don't do visual checks, and the removal of the aforementioned parts do not throw a CEL since it doesn't touch the o2 sensors.
Also, if you plan to go with headers in the future you can get random tech cats, that way you will still have cats and will pass inspection.

My first mod on the ISF was the Borla axle-back. I simply can't recommend it.
It sounds great at startup, and from the outside it's really nice. But inside the car it just doesn't have that great of a sound. So what's the point if it doesn't sound good to the driver? Don't let the youtube videos fool you. It does sound good from outside the car, just not inside it (which is more difficult to video).
It essentially just adds volume to the stock sound. But it also adds some boomy-ness to the cabin, definitely more-so than any other ISF exhaust I've heard (save but the loud-as-hell ISS QES).
Overall my wife didn't mind the Borla though, so it did pass the wife test. But she's had to put up with some crazy Evo's over the years so cruising in the Lexus is a huge step up and likely a bigger approval factor than the exhaust.
The Borla cat-back on the other hand sounds way better and is barely more expensive ($1k vs $700). If you're considering headers in the future, I would suggest doing just a cat-back now. Best bang-for-buck plus it sounds way better than an axle-back.
