Hey guys so yeah Like the title says I just need some help with this exhaust. I just bought it and was about to install it. BTW Its CNT brand name cat back exhaust and its for my 2004 wrx. Untill I noticed there was no spot for my rear o2 sensor. I did some reading and hear its no good to run without it, unless tuned. So yeah Im not to sure what to do at this point.
Nvm waste of space on the forum.
