Muffler Question

[GSX360]

does anybody know what would be the best muffler to put on a 2005 Sorento Ex....im thinking about flowmaster but i dont know which 1...theres a lot of em...and if flowmaster isnt the best 2 put on...what is
((((i only want to change the muffler..not the whole exhaust system))))
would changing the muffler void the warranty, and if so, what would be affected by this void in warranty??

Thanks in advance

the truth is that it's kind of up to your dealer but they shouldnt void your warranty. I can tell you that at the kia dealer I work at we have plenty of kias with all kinds of mods and no one has being voided due to exhaust enhancements

sorry as long as you keep the cat and oxygen sensors in their original locations
