Im guessing its throwing me the CEL because the fumes and heat is overbearing the sensor? I just get it a day after the downpipe. i had it cleared once and then its back again..

Don't guess. Find out EXACTLY what DTC you are triggering. Then we can better help you with the solution! If you want to guess, thats cool. You can start with just replacing your 02 sensors, while your at it, get a new ecu and you shouldn't overlook the engine. It may need to be replaced.
What I am saying is regardless of when you "triggered" the cel, the DTC could be anything. It may just be a considence that it happened after the install!

I went to the shop and the guy said the DTC code was because of the downpipe, its common too it hasnt only happened to me but with most of my friends who get a downpipe so its just the O2 being ****

Ok, well you are assuming that the guy at the shop read the code correctly. All I am saying is for us to give you an accurate 100% fix, we need to know the exact code.
But under the assumption that it is the 16804 - Catalyst System: Bank 1: Efficiency Below Threshold

Maybe next time you will be prepared with the information we need and therefor you will be able to get the answer you need on your own!
