Wondering if a turbo back exhaust for my S70 T-5 (like the OBX kit) is gonna mess up any of my check engine light etc? I'm not very familiar with where the sensors etc are located. Also what are the advantages of a catback vs a turbo back....

 

If i am not mistaken OBX's turbo back has a catless downpipe. That is technically illegal, well in state of texas i know it is, but they use a spacer for the o2 sensor so that it will not throw a code and you can pass inspections. Turbobacks offer the best noise and power.

Catback is generally less expensive and easier to install. They still can increase power and generally change the tone of the exhaust.

 

Ohio = No inspections I dont care about it being less than legal haha Thanx for the info. So that should not cause any issues then.... Can u define spacer a bit??

 

Very jealous.

there are two o2 sensors on the dp, i think (atleast for my car)
And generally how they work is that there is one before the cat, and one after, and unless there is i believe, 20% change or higher, it won't through a code. But if you take that cat out then there isn't a change, so what the spacer does is remove the tip of the o2 sensor from the direct exhaust flow, allowing for it to read a 20% change, i.e. not alerting your ecu that the car is failing emissions.

 

ahh ic that makes sense thanx for clarifying, yeah to inspections is awesome. Plus my dad is an ex mechanic and has 3 of every tool of ever made haha so i can do most of the work myself with out having to worry about having a catless exhaust

 

Works out well then, OBX is a pretty good deal for what you get.

 

Here is a good video.

Personally i like custom exhausts, but i do like mine louder.
