Synergy has the RMM Exhaust, which is pretty mellow with no drone at any speed. They don't open up unless you jump on it and go over 3k rpm.
He removed the resonators a while back and now there is MUCH more low end grunt at a lower RPM.
Deeper ? Yes
At a lower RPM ? Yes
It is just a little louder at freeway speeds. Not ricey or "sick loud" . The biggest change is taking off from a stop light. I have the RMM exhaust with resonators and it is pretty quiet from a standstill. On Synergy's car, the deep growl comes in earlier. Sounds like a smooth sounding version of a Mustang GT type of growl. Highly refined and not raspy sounding.
Play back this video of our SF cruise meet last year. You will see the silver GS with the TTE front lip and 20" Dronells. That's Synergy's car. Note there are 3 other silver GS's so look for the one with Dronells or the TTE lip.
You can hear his car take off on a couple portions of the video clip. http://www.lexusgonewild.com/meets.shtml
Here's an exhaust clip we recorded a few years ago for further reference: http://www.lexusgonewild.com/videos.shtml
I would think any mellow exhaust is gonna sound the same.

i jus had a post on redoing my exhaust! i gutted my cat and although on a SC3, it was nice at the time. but right now the sound gets to me: too loud! at approx 45 and 75mph it is the loudest and cruising at 75 can be pretty annoying, not to mention attracting cops. so im probably gonna replace the straight pipe with a high flow cat and get rid of my resonators. i lost low end power but might have gained a little high end. anyways good luck on your exhaust!

Also you have an SC3, that motor will never sound as deep as a V8 and it can get raspy. An SC4 will sound a lot like a GS4 though.
If you wanna hear an SC3 or GS3 with no resonators, listen to LXOGOODs car on the exhaust competition video clip I provided. There is quite a difference on a 6 cyl motor.
Like I said, Synergy had a very mellow aftermarket exhaust with removed resonators.
Taking out the cat and doing it on the 6 cyl will yield a completely different result.

Custom 2.5 inch mandrel bent pipes from the 1st pair of cats, followed by an X-pipe (3rd cat removed), straight through to the L-tuned mufflers. (Resonators before the mufflers removed).

To date in my opinion the sweeetest sounding exhaust on a GS400 yet!!!!
Turn up your speakers and enjoy the show everyone!!!!
