It won't be legal unless it gets CARB certified which I highly doubt RR will be willing to jump through the hoops for.

I did see the 2 videos for the rrr is500, and also watched a ton of rcf/gsf clips. At the very top end of the rpm range I think I can hear what possibly is rasp, but maybe it's the mic topping out. Or maybe just the sheer scream is hard to capture on a recording lol. I figure the high flow cat could also help mellow the exhaust slightly which I wouldn't be that opposed to.

So I finally got time today to check at cold start with valves closed there’s no gas smell and with valves open there is a faint gas smell which goes away I also redlined the car with valves open and didn’t get any gas smell. And yeah the hi flow cats def will help they had a rcf te that got those and it still sounds great and I’d def much more mellow.

Has anybody here who got a full catback exhaust been able to fit their stock midpipe and mufflers in the IS500? Just curious. Thanks.

the mid pipe might be an issue but I was able to fit the aftermarket axleback in the trunk width way. Idk if you can fold any of the back seats down, but if you can, you’d be able to fix the mid pipes. Unless they’re shorter than the axleback, then they’d all fit in the trunk. But I think those are longer and wider so probably not.

In this IG post, it shows everything from GTHaus. Now I would assume it would be similar for the stock parts. Im sure they’d separate the mid pipe for you.

That's what I'm saying. These exhaust prices are on the ridiculous side. Tempted to just have a shop put a couple valves on my stock exhaust, dump em out the bottom

Enlighten us! I know very little about aftermarket exhausts in general and am too lazy to google what you mean. On a side note is it weird I don’t consider Lexus a luxury car? LOL. Maybe I’ve been looking at too many Lexuses but to me they’re just standard cars. The bare minimum standard I’d personally want to own. Does that make me bougie?

Also, If you could download a decibel meter app on your phone and measure I would be very grateful.
