Looking to buy some eom mufflers i need to take my car to dealer but will void warranty if I don't have them

 

Are you positive?
I'm not sure what you did to your exhaust but you should not have any warranty issues as long as you have all three catalytic converters still installed and are in compliance with CARB requirements.
I have two I could sell you off a 2010 but would hate to take your money.

This is from the FTC:

Will using 'aftermarket' or recycled parts void my warranty?

No. An 'aftermarket' part is a part made by a company other than the vehicle manufacturer or the original equipment manufacturer. A 'recycled' part is a part that was made for and installed in a new vehicle by the manufacturer or the original equipment manufacturer, and later removed from the vehicle and made available for resale or reuse. Simply using an aftermarket or recycled part does not void your warranty. The Magnuson-Moss Warranty Act makes it illegal for companies to void your warranty or deny coverage under the warranty simply because you used an aftermarket or recycled part. Still, if it turns out that the aftermarket or recycled part was itself defective or wasn't installed correctly, and it causes damage to another part that is covered under the warranty, the manufacturer or dealer has the right to deny coverage for that part and charge you for any repairs. The FTC says the manufacturer or dealer must show that the aftermarket or recycled part caused the need for repairs before denying warranty coverage.

 

i have some 09 mufflers, but agree with the above poster.
They can't void any warranty, unless the part you put on broke something, and only then, the warranty can only be voided for something directly related.
