Is this much exhaust soot normal???

[yzark99]

Normal. If you want clean, install hi-flo cats.

I have hi-flos on mine with headers and tune and still get the same thing. I could clean them after every run (and do so it's easier to keep clean). I always wondered the same thing....why? I'm going to check my CAI filter and it's a 2011 so maybe new plugs?

The only "problem" is the tips are flared out and soot is noticeable....Every exhaust pipe looks like that on the inside...Quit looking at it, and the problem is solved...

It's like wondering why water is wet.

A catch can won't void your warranty, it does no harm to your engine it only makes it run cleaner. They would have to prove the catch can caused a problem before they could void your engine warranty. If your dealer says it will then find a new dealer.
I've had a catch can on mine for 4 1/2 years and it has never even been mentioned over many service visits.

Smoke em if ya got em!

There is a 5th gen forum member that had a warranty claim for his failed oil pump denied because a GM rep was aware that the owner had a catch can. They used the catch can as an excuse with a BS technical explanation. It can be the luck of the draw depending on how/what is reported to GM by the dealer. I also read a thread regarding a 6th gen owner having their warranty voided because of a catch can installed.

I agree no mod installed should be assumed to not void warranty. What Angrybird says might be fine if the car winds up at your preferred dealer but if it cacks on the side of the road and goes somewhere else all bets are off.

I'm tuned but I understood my risks before I took the plunge and accepted them.

What the dealers will try to get out of warranty work is so ridiculous.

I mean don't some of the models above the SS come with a catch can from the factory?

According to the law they had to prove how a catch can could cause an oil pump failure then show that the catch can on that car did it.
There have been many instances of oil pump failures and GM knows about it.

I definitely would have made them explain how it caused the problem and put it in writing.
Many people just accept what the dealer says and do not force the issue.

Tunes are very much different than a catch can.
The burden of proof still falls on the dealer/manufacturer.
BTW there are many threads in Camaro5 explaining this, so I am not making this up.

That forum member made that post and when the questions started to come he disappeared. I can only assume there was more to it than a catch can.

A catch can is a modification, replacing an OEM filter with an aftermarket filter that meets manufacturer specifications is not.

It would be up to you to prove the modification could not cause an issue, and you can't.

I used to say the same thing that it only applied to service parts. I agree in some cases you cannot prove the mod could cause the problem, but there are many cases where there is no way a particular mod can cause an unrelated part to fail. Any knowledgeable service person would know and be able to prove it.
If what failed is a known issue and you have proof that it is a known issue such as a TSB number it is hard for them to use that excuse.

Here is a good explanationo on the steps you should take if you are denied a warranty claim due to a mod.
