Curious to see if anybody has installed these. Would like to get a review on installation and performance.

 

From what I can see, these will definitely net you a decent amount of power because they remove all four catalytic converters. The downside is that you'll need some type of conditioner to prevent the CEL from coming on. You'll also get noticeable increased exhaust odor.

 

But that's not alllllll...

Act now, and you can also get your very next smog test(s) to strike out...something about removing equipment required to keep your skies blue...but there's even more...

You'll get a drone at highway speeds, sometimes slower, from the exhaust. A lot like a root canal as long as you're driving.

Please report back with pics.

 

The conditioner or tune would take care of the the ODB test. You'd fail smog and visual test if your state has those. There will be very little drone if any at all. The mid pipes only remove the cats. You keep the stock resonator and muffler and I believe they even come with their own resonator as well.

BTW, I'm not advising for or against doing this. I'm merely answering the OPs question since I highly doubt anyone here has done this.

 

Its sounds cool... but...

as a former owner of a Porsche Cayenne Turbo, the engine uses/burns about 1qt of oil every 4K miles (I know it doesn’t sound normal, but it was). I always wondered where these deposits went, so about 80k miles, low and behold the check engine light comes on and the emission game begins. Turns out one of the cats failed (I’m guessing because of oil residue) so I took this opportunity to replace with some cat-bypass pipes for that extra throaty noise. The noise, fantastic - the bad side, I never got the check engine light to stop coming on about every 600-1000 miles. Really not my cup of tea in an expensive vehicle.

my point: The LC’s are not performance vehicles, and they are some of the cleanest burning engines out there - meaning cats rarely fail. Taking a perfectly working cat out and replacing it with something aftermarket that will almost surely trigger the dreaded check engine light sounds terrible to me. I lived it, hated it and love our LX570 and that naturally aspirated V8 just the way it comes out of the factory.

to answer your question - I doubt there is anyone in this forum who has done it, maybe check ih8mud in the 200 series forum on the LC’s.

 

And I'll add even more...you'll have the advantage of a lighter wallet.

If you really believe that Doug Thorley has a better performance engineering group than Toyota/Lexus, I'd say go for it.
