hey joe-z, i know you used an x-pipe because it showed previously to provide the largest gains. but did you test this yourself, creating your exhaust w/o an x-pipe vs. one with one to gauge the differences?
at the same time your argument holds that no performance part is the same across manufactureres, an x-pipe in one exhaust might or might not be the reason for a higher gain than another one.

For the record, during the R&D process we tested No connection, H-connection and a couple of variants of the X-connection...
The X-pipe connection performed the best and we designed the front section out of 2 solid mandrel bent tubes that join at the X or )( connection.
For the best airflow possible.
Thank You

I don't have an IS but I am curious to see how well it does during a smog test.
I was very surprised when I took my 2001 GS300 in for a smog test.
HC @ 15mph was 2ppm and 25mph was 1ppm.
0% CO and 0% NO.

i have a friend who runs a true dual exhaust on his car (not a lex) and he told me there was a loss in low end torque when you run true duals. did this happen with this particular exhaust? or was the xpipe able to salvage the lost torque?

So I just got the exhaust installed and I'm having a little bit of an issue where the right side is a little lower than the left side. Could someone please explain how exactly to adjust this with the rear bolts/section? Thanks in advance
I appreciate your honest and detailed opinion...
On the plus side to your points. The 2 rear axle sections are flanged as you can see in post #1.
There is room for adjustments to those 4 bolts, which will control how high / low the tips sit off the bumper exhaust cut out holes.
For example on my car when we first installed it and took pics, there was a 2 finger gap.. After the exhaust burned and settled in its place, I went back and loosened the 2 rear sections and adjusted as high as I could..
Which is just about a 1 finger gap now...
Perfect if you're running an aftermarket lip and want to adjust how high or low you want the exhaust tips to sit.
The mufflers are not lower than stock. If anything they might be just as high or slightly higher..
They are just a lot more visible since they are polished.
The tip design is finalized for these two versions.
Before adjustment
After adjustment
Enjoy
