I'm inspired, I want one, anyone knows of how CA rules affect this muffler (sorry for hijacking)

Honestly, I don't think it's actually a "muffler"... But, I'm close to some local safety/IM guys (i.e. I work with them
), so I won't have a problem. It's about the same sound level as a GMC Yukon with the Denali exhaust system. Which I like. And again, NO WHISTLE!!
Are you running catalytic converters? If so, and it hasn't been done yet, and you want a deeper tone without a whistle.....gut them.
Before I removed them for straight pipes I had the same setup and it sounded GREAT. Low rumble until >~2k rpms then has a growl to it....real nice.
Now with straight pipes instead of cats (to fit sliders) it sounds a little raspy until >~2k then you should hear it...truly sounds like a big ass diesel. Have had people ask what diesel I'm running. Some black smoke out of the exhaust pipe helps too. Not gobs of it, but little puffs when I yam on it. But with no restrictions in the exhaust it kinda makes sense.

Haha, I had a friend who owned an 82 Toyota pickup with a flat bed. He put a stack on it, came out right behind the driver's door. It burned oil, too, so whenever he throttled it, smoke would billow out of the stack. It was awesome.
I've always wanted to put a stack on a diesel VW Rabbit P/U...
Gut 'em! Take a piece of pipe or rebar and jam it up in there. Wear glasses and a filter mask. Just pound the stuff till it's all loose then get it all out. Then for all visual purposes, you still have them.
Yes....illegal in all states. So I guess I'm suggesting for 'off-road use only'. Throttle response was a little better after that at cruising speeds. And the sound is amazing.

Quiet you.
I would, but it barely passes the sniffer test as it is.
Very curious about the ramifications at the emission test station as well...not the visual inspection but the actual measurement of particulates.
I have two vehicles where I've recently had the cat 'flanged' on both ends (so you can take it in and out) then gutted them and put them back on. Emission are now coming due on one of these. I'm wondering if I'm going to fail due to increased particulates and be forced to go buy a new cat, have it flanged in the same manner, and install just for the test.

No idea on emissions, none in my county period...none in NC for anything but OBD2.
I've used those many of times in the past. Granted, we mostly used the cherry bomb mufflers as resonators and still use a hi-flow muffler in the back of the car. The red paint burns off after a couple of weeks and it blends in with the rest of the piping.
The sound isn't bad on the FJ80. Although I'd wonder how loud it really was when driving next to solid structures (walls, buildings, etc). At least with the longer tail pipe exit, that will bring some of the noise down a bit, but not much as a conventional muffler.
They have nothing to do with emissions, as you can still pass smog with it (I've done so in CA many of times with different cars). IMO, they're best used as a resonator that you're adding to an existing hi-flow exhaust system, but you can use it as a muffler if you really wanted to.

If it is barely passing there could be something wrong... mine zinged passed the CA sniffer with flying colors
