I want to keep my stock exhaust or leave it to as quiet as possible cause having an exahaust is annoying and dont want it anymore. But I wanted to still put headers on. Can Headers fit on my stock exhaust?

 

Yup, it may require a little modification depending on the setup but most are meant to work this way... I hate aftermarket exhausts too but most of our cars besides the ones that have to be NHRA legal just run open header everywhere... You probably don't like that tho as it can be annoying... Swapping from an aftermarket to a stock exhaust will have a downside to the performance but that's what you pay for being quiet... Just my $0.02
