My H Pipe is sitting in my living room on my couch taunting me. I want to have it installed but i don't have the MILs. I've done my research and Ive found that having an o/r H Pipe with no MILs will cause my check engine light to remail on. Of course i plan on getting them later, i just don't have the money now. Is it hard to install the MILs after the o/r pipe is on? What would you do?
