Thanks Joe! Yea I finally removed all the pieces and fit it in the trunk, I could barely see out the back window with that box there lol.
I don't have a truck so I'll try just lowering the passenger seat and putting the pipe diagonal inside the car to see if it fits (from front pass seat to rear driver's seat). I'm obviously going to thoroughly clean the pipe and use towels to protect the interior before I stick it in there.

I'm not going to lie... You can try, but it really won’t fit... The OEM midpipe is ridiculously BULKY & LONG
Not worth jacking up your interior... Find a friend with an SUV / Minivan / pickup truck..
The 2 - OEM muffler sections will fit easliy in the trunk..

Hey Joe
Tremendous applause for what have you done for the 4GS.
Just needed to know if I should really wait for the full system for AWD or just go for the axle back. There are numerous members that shown their interest for the full just in this thread alone.
Is this a future reality for us?
Thanks

I am originally from NY too... 
The reality is right now we only released the Axle Sections for the AWD...
We haven't even been able to get an AWD GS on a lift here in SoCal.. But we have spent countless hours in the R&D process..
What we found on the IS350 AWD (not long ago) is that the forward front transmission drive shaft + extra trans mount get in the way of our X-pipe design..
As you can se we have a very unique X-Pipe design in our exhaust.... Actually companies are starting to replicate our designs as well...
Must be that good.

Easier explained if we had a photo of the underside of a GS350 AWD..

First I have to say, I got the exhaust installed today and it sounds AMAZING! Now yes it is loud and it definitely drones, but with the music at about 20 it's unnoticeable. I still love the sound and can't wait to break it in to see how it sounds after, overall I'm extremely satisfied with this exhaust. 
I was able to fit the mid pipe in my girlfriends RX350 no problem, and the 2 end pieces did fit in the trunk perfectly.
Awesome... Deboxed fits perfectly in the trunk....

Ok guys so I just got back from the dyno and here are the results below:
Before JoeZ exhaust install - max RWHP 270 TQ 250:
After JoeZ exhaust install - max RWHP 277 TQ 254:
I have to say I'm happy with the results but I expected a bit higher numbers (keep in mind I still only have the OEM exhaust). But if it matters, it was a hot rainy humid day in Miami so it may have slightly affected the numbers.
Here's some more pictures of the dyno;

^^^ Awesome Congrats..!!! Those are some good numbers...
Especially for HOT weather testing..
Did or can they get you the data re-graphed under SAE corrected ??
We averaged 10 Rwhp gains during R&D on a SuperFlow dyno.
Congrats Again!!
Launching in Sport+ Mode should feel much better now..

So I'm coming from a long time owner of Mercedes and bmw v8 motors. The exhaust on those cars come out beast. I'm hesitant to do an exhaust on the 13 gs350 f sport bc 1) I don't want a loud annoying drone inside when I drive in low rpms and 2) a nasty ringing sound on the outside when driving. What do you guys suggest. Also what's the word on the intake from the is350s. Compatible?
