If I put a downpipe with no cat will I get a CEL?

Thanks
Carlos

 

yes you will

 

sure will, you will have to get someone with hptuners to delete it for you.

 

If you look at our car wrong you'll get a CEL. So a downpipe will throw a couple codes probably.

 

Thanks for the info guys I'm gonna do it anyways

 

You will have a P0420 code I believe which is because you do not have a cat. If the CEL comes on, which it will about 50miles after you install it, then simply unplug the battery for 5 mins and put it back on. That will clear the code. OR you could just simply buy an interceptor gauge and clear it from inside of your car right away.

 

what's an interceptor gauge?

 

an interceptor is a gauge, like your boost gauge, that shows you A LOT of different things about your car. I highly recommend you get one. It shows iat1, iat2, which is where i leave mine at, it also scans for codes, clears codes, and shows a lot more, has a shift light, etc. Its pretty cool.

 

doesnt it just plug into your obd port or what? where does it get its readings from?

 

Installation is accomplished by simply plugging the supplied connector into the OBD2 port
below the steering wheel and connecting a separate included wire to a switched 12v
vehicle power source. Virtually plug-and-play!

That does NOT clear a code, just resets all the car's monitors. You still wont pass inspection like that b/c all the monitors will show as not ready until they reset.. and when they do will prob throw the CEL again. Not a permanent answer to your problems.. lol.

 

yep ull throw codes. enjoy
