Not necessarily true. Under the Magnuson-Moss Warranty Act, the dealer has to prove that any issues the vehicle experiences are the direct result of the mods. If they can't prove it, they have to cover the repairs under warranty.

I concur.

I ran cars without cats for years and dealing with the fumes gets a little old, especially during the winter months.

If you run headers on the vehicle and let's say the motor blows up, they can easily say that due to the increased exhaust flow, it caused the engine to lean out and detonate (which it could/can). The Magnuson-Moss Act is good for certain things but there's still gray areas.

If you're not in good with the service advisor and worried about the powertrain warranty, I wouldn't touch the headers.

True. But all the dealer needs to do is decide that your mod was the cause of the issue requiring warranty work. Then it can become a drawn out pissing contest which can be time consuming and expensive. Dealers are often not full reimbursed by GM for their warranty work, so a dealer has a financial incentive to find a reason to deny it, such as a modification. Some dealers are more mod friendly than others, but simply pointing out the legalities of the law will not, often times, cause a dealer to change his mind

Anything that does not mess with the cats you are okay warranty wise. Replacing the cats and tuning makes it questionable.

Sure, there are grey areas, just like every thing. My point was that modding the car does not necessarily mean the car's warranty is void. It's not an all or nothing thing. Modifying one aspect of your vehicle does not void the entire warranty.

Correct, and it is good to be more clear here as you have done.

The issue with some mods, there is so much downstream of the mod that they can tie in so many other parts.

A tune, forget it, power train warranty gone. Your headlight goes out or power seat stops working, those need to be repaired under warranty still.

Don't forget, the MM Act is specifically for OEM equivalent replacement parts. It started as a way to prevent a dealer/MFR from denying a warranty claim because you put in Brand X oil instead of their own (or pick any other part).

A replacement part that is NOT an OEM equiv (different oil spec, or a high performance part designed to increase horsepower/etc) is not covered by the MM Act. Period.

So while you'd probably still win in court if they blame your headers for, say, an infotainment failure (which of course no dealer would ever claim so this would never happen..), you certainly will never win if they blame it for literally ANY powertrain/drivetrain failure.

I find it odd that so many camaro owners run catless, but on the VW forum I was on, everybody talked down about doing it and lambasted people for having done it.

Is there a reason that it seems more acceptable with the Camaro crowd? Just curious.

I'm just guessing but I think possibly blue collar VS white collar mentality?

I am not a fan of cat-less, at least not primary cats anyways. I did remove my secondary cats, but that was more so I could remove my stock system without cutting and use it if I needed to go back to stock at some point.

I have headers and no cats on my C5Z and have never had fumes in the cabin and the car is quiet at normal highway driving speeds. My favorite performance mod on my 'vette. Not sure why an SS 1LE would be any different.

The bigger issue to me is the warranty, but my experience is that anything cat-back isn't a big issue for most dealers.

And I'm just guessing but I'd say it has nothing to do with "collar color" based on the number and types of vehicles most of us drive in addition to the Camaro.

My catless 'vette still passes emissions and I don't think anyone associated with VW has any business throwing stones over emissions regulations......

I just installed the Borla 60606 mid pipe with a Corsa Xtreme axle back this past weekend, and I love it. Very loud at WOT but silent when cruising, and not too obnoxious under part throttle. Here's a quick bumper cam video.

Not necessarily. In my experience
