Also JoeZ: You should engrave your exhaust like other exhausts company with your own Joe Z logo
Joe's exhaust has a deeper tone at low RPM's. It sounds a bit sportier.

The low RPM's are where this exhaust shines. Don't get me wrong - it has a nice sound at full throttle, but it's really menacing at low RPMs. I've also noticed a bit of droning on the Lexus HKS. I still can't believe how little droning there is on Joe's exhaust. It's very 'daily-driveable.'

It's definitely louder than the Tanabe, but the tone is similar. Think Tanabe on steroids. You can indeed hear it at idling - but only if you're outside the cabin. When you're inside all you hear is the engine.

Hope this helps everyone,

Javier

We had a Base run with a 265 rhwp pull, but some how the data file was lost.
So we had to use the base run for the graph which shows the 262rwhp base run pull..

Below is the dyno graph of the Base run verses the "Street Performance" version w/ CATS.

- Gains will be approx 8 peak rwhp on this system.

Below is the dyno graph of the "Street Performance" version w/ CATS verses the "Race Performance" version w/ OUT CATS

- Gains will be approx 10 peak rwhp on this system.



Thank You

Thumbs up

Joe took me for a ride in his SGM last Sunday after test fitting his black sleeves on my car for his pipe. All I can say with this is - -
JoeZ intake+JoeZ exhaust = HP fun!!!

javyLSU pretty much summed it all up. It has a deep tone and sounds very sporty. No droning inside the cabin (wife & baby friendly ) When Joe left my crib he opened the throttle going up hill and down hill - - the note is just lovely. When the sound clip is up and running then you will know what I mean.

I took some rear photo shots of his car:

Joe,

Sweet looking exhaust dude Are you gonna sell the midpipe seperately? Or do we have to purchase the whole system?

Hi Mike

The Dyno was completed on a stock IS350 which only had the exhaust upgraded for the DYNO's.
Also, testing was done in normal mode and only up tp 4th gear...

I updated my original post with this info..

Thank You

^^ This system will not work in conjunction with any axle back system on the market.. Since those only have a single pipe connection.

^^ That is incorrect... Please focus on the Dyno Graph range 5k rpms +
Anything below 5k rpms is not really measurable.

Thank You

Do you mean just the second middle section??

There are 4 sections in total.

These components are designed for this True Dual Exhaust system.... and would not work in conjuction with anything currently on the market.

Currently we are looking at the possibilities of creating a short Y-Pipe connector which will allow the 2 rear muffler sections of this system to bolt up to the OEM axle connection at the oem resonator.
There is NO ETA for this piece at the moment.

See post # 22 in this thread for weight break down on this system verses OEM.

Thank You
