Hey everyone, New to the site so if this isn't the place to post I apologize. I was wanting to know if I put headers on my car and got it tuned would that void my warranty? ThanksTrent

Just headers, no. Tuning the ECM, maybe. Sometimes you can take the tune out and they will never know, but if they do find out they can use that to deny warranty. It's also possible they won't. It's impossible to say for certain.

Ok thanks that makes sense. I just can’t get the sound I’m looking for with my scat pack. I deleted all 4 mufflers and it sounded louder but not throaty. So I put on wicked flow mufflers and they made it a little louder but still not like my friends stock 5.7 with all 4 deleted. Can’t figure it out!!!

These cars require an unlocked PCM for tuning. That means you will have to get one from a company like Diablo, then swap your stock PCM. Doing so means your mileage will not match up to the car (i.e. red flag to service tech). There is also a write counter that shows the number of times the PCM has been flashed. If your counter does not match the vehicles service history (i.e. dealer flashes are only counted), another red flag. So can't just get your stock PCM unlocked either without leaving a trace. Either of these will ensure a powertrain warranty void if the logs are sent to Dodge.

So short answer, a tune will void your warranty if they have a reason to go look for the presence of one.

Headers alone are a bit more iffy. They are considered modifications, and if something breaks could become a reason to deny coverage. However they don't change the whole engine operation like a tune does, so not as likely to be a cause of a denial. People have had claims denied over CAIs, cat-backs, you name it. So be prepared to pay if you decide to mod in warranty.

I've always heard that a cat back exhaust is OK but messing with the cats or anything before it (like headers) is a no no as far as warranty goes.

Depends on the writer and tech you get, but if you have major engine damage all bets off, you pay.
