Can someone post a pic of exactly what and where we are talking about?? I would greatly appreciate it so when I go to do this I will know how to tell them what I want them to do.
Thanks,

OK. I thought that maybe the stock exhaust would be pretty restrictive thus removing the resonators would be pointless. But now that I think about it, to get the 4.0L V8 as quiet as it is, I would see why they need 3 resonators to keep it "Lexus quiet." Is there any other purpose for the resonators besides dampening the sound a bit? There is no smog purpose right? I'm just wondering whether removing the resonators will cause a bit more hydrocarbons and nitrates to be emitted into the atmosphere. I live in Cali so that wouldn't be good. I hope it doesn't seem "ghetto" that I am entertaining the idea of removing the resonators on a completely stock exhaust system. I already have Borla tips (from previous owner) which look great. I think even the tame Borla mufflers would be a bit too loud for my taste. I want a very subtle, low tone like you hear on AMG MB models (SL55, S55) during startup and acceleration from a dead stop. Anybody have pictures of their setup (3 deleted resonators with crossover pipe)? I've searched and have seen only videos. I think I'll purchase a 2.25" X-section and have my muffler guy weld that in.

sleeper408, the borla exhaust is one of the quieter exhaust for the GS4. You only hear it rumble when accelerating, and once you're cruising, you dont hear a thing at all. So basically it's an OEM system once you're rolling.
I have been thinking of removing the x-pipe and then slapping on the OEM exhaust just to hear what it sounds like. I'll probably do it within the next few months

So to clarify, there are two preliminary cats right after the headers-- one on each side, then it merges into the 1st resonator or is that the main cat? I'm trying to figure out whether the small muffler looking thing is actually a catalytic converter because it doesn't look like a traditional one with the heat shield. Then it splits into the Y-pipe where there are 2 more resonators, but these are solely for noise reduction purposes. Followed by mufflers on each side. So basically, do not remove the 1st resonator (cat?) if I want to pass smog in Cali.
