This was done on my friend Phil's IS F. I've driven this car and heard the exhaust from outside. This is how the IS F should have came from the factory. The exhaust tone is not annoying, it's very pronounced, throaty and does not sound like a muscle car V8!!! As you can see, the gains on this exhaust are pretty impressive.

Thanks to the folks of Performance Tube Systems & Joe Z here in SoCal..!!
I am finally happy to share some pictures, videos & dyno's of my IS-F.

The PTS Full True Dual Exhaust sounds simply amazing.
It's a 2.5" true 304 Stainless Steel mandrel bent system.
It will come with an integrated X-pipe and many other quality specs. Including Fully TIG welded.
It is similar to their current design for the IS350, offered via www.CarsonTuned.com.
However, it has quite a few changes to accommodate our V8 engine & 8-speed transmission.

This secondary cat less system has measured gains of approximately 22 rwhp and 18 ft lbs of torque.
The independent Dynos were done in 5th & 6th gear...
The 6th gear run will be used to display the most accurate results. This represents the closest 1:1 gear ratio. However, the graph is a bit choppy due to the noise interference through the dyno, from the car reaching top speed of 170 mph!!
My car was Dynod with the stock intake during the exhaust testing.

* Exhaust Weight Facts *

OEM Exhaust System (2 sections)
Front-Mid section = 33 lbs
Rear Axle section = 37 lbs
Total = 70 lbs

PTS - 304 Stainless Steel Exhaust (4 sections)
Front X-pipe = 16 lbs
Mid section = 19 lbs
Rear axle sections = 29 lbs
Total = 64 lbs

I only have a few pictures of the exhaust at this time. Better ones will be out soon I'm sure.
But we did take plenty of video during the Dyno & also some really nice driving videos..

The intake pipe setup.

The Joe Z Intake Pipe design has been around since 2002 and is currently available for the IS300, IS250 & IS350.
Which all use a 3" pipe constructed of 6061-T4 Aluminum.

This version for the IS-F uses the same material however, it is constructed with a 3.5" aluminum pipe.

The independently dynod intake had approximate gains of 5 rwhp, per the results. Not much, but I am not looking for anything too loud with the intake. Plus our Dual Stage Intake design is not something I want to remove or mess with.

Joe had this first one made Anodized Blue just for me.
It just so happened to match my Ultrasonic Blue pretty good.
The sleeves in the pics were just temporary. He got me black ones now.
My car was Dynod with stock exhaust during the Joe Z Intake testing.

Enjoy the pics:

Any idea on when we can buy the exhaust? I love the way that sounds

finally some R&D for the IS-F. What are these guys credentials though and what is their history with the aftermarket?

i like the way the intake looks, its nice, and it sounds very nice as well...

Sounds great.....

looks nice guys.

That sounds really great. Although I've never heard mine from outside. I've always been inside when someone else has driven it.

JoeZ has been doing intakes for the IS community for quite some time now. he's well known on both IS300.net aka my.IS and Club Lexus. His products are carried exclusively by Carson Toyota/Lexus Parts aka L-Tunedparts.com a long time supporter of the Lexus community. A lot of us veterans that migrated here including myself timers on CL and my.IS can vouch for him.

Can we order now? IF so can is send us a contact name and number.

Thank you,

I'm nearly positive it's not available for purchase yet. I believe they are still working out pricing and other factors. As soon as it's available I'm sure it will be posted up :)

Correct. This was the first one made for the IS F. Production and availability to come.

hopefully the pricing is reasonable

With all candor and no personal denial how does this exhaust system sound in the car? Specifically at highway speeds of 60 - 90? Is there any of the typical aftermarket exhaust droan? If not than this is a no brainer. I do appreciate the pictures and the hard imperical data to support the perfromance gains.

videos are posted on youtube

If you go to post 1 of this thread, the first 3 pictures you can select are videos off youtube. If you want the link directly, I copied it and pasted it below. There are at least 3, interior, exterior and dyno

I am really interested in the Borla system as opposed to this one. Borla typically has a much deeper sound than the average after-market exhaust. However I believe this system is going to be Borla to the punch! I'm just excited to get something on the car already!!!

I agree with you Fuji I am waiting for borla, but I like the way this exhaust sounds aggressive and the power gains are impressive.

Borla makes great products, but some of their exhausts tend to carry more exhaust drone at highway speeds. It can get pretty old quickly. This PTS/Joe Z exhaust sounds amazing in person. I've driven the test car at various speeds and conditions and let me tell you, this is how the IS F should have came from the factory.

Hey Flip no drone at all?

The exhaust is now available for preorders on the l-tunedparts.com website. I believe they will be shipping it beginning in the middle of November. See the link below :)

Thanks Mike I already ordered mine.

Just checked the Carson Toyota website today and the exhaust system is available. $1,599.00 Ready to ship to a ISF near you.

Will this exhaust system pass smog in California??

According to a Carson-Lex rep. they will be released mid-November and these are for preorders. I would call and talk to them about it if you have any questions :D

Will this exhaust system pass smog in California??

I would contact them or Joe-Z about this for sure

whats the different with the stock intake and Joe Z intake other than material?

there is a $300 discount for the groupbuy.

Hey, I noticed that Carson Tuned is selling the PTS Joe Z exhaust. You tube has a dyno, exterior and interior video. Sounds really good and dynos 22 rwhp! They are selling for $1,599. Should I order it or wait a little longer for Post SEMA? good HP increase and sounds great! I am growiing impatient.

There's a whole thread on it below :) It's up to what your looking for in the exhaust. Joe-Z's sounds mean and keeps the stock tips. A lot of the SEMA are complete aftermarket and get rid of the tips. The exhaust is in production and will be shipped out sometime in mid-november last I heard

what are you planning to do? I want exhaust asap, but I don't want to jump the gun if we might see better options, not sure I care about the tips. I have seen some other options and the tips don't look so perfect.There's a whole thread on it below :) It's up to what your looking for in the exhaust. Joe-Z's sounds mean and keeps the stock tips.
