corollas

My 2014 Corolla S has a borla muffler on it and I have been wanting to remove the cat n resonator to get a little bit different tone, will I throw a check engine light? N if so how can I get about not having a check engine light for it?

hey guys I'm just wondering if anyone knows if it matters what kind of fd2 type r spoiler I get there's a couple different ones on eBay but all look the same just some are cheaper I know you can get this spoiler on there because I've seen pictures and asked the person that did it .. If anyone...
