Dynatech High Flow Cat

[redrider07]

Ok, I already have a flowmaster 80 muffler with dual tips, but want to get rid of the stock cat. The cat I want is a Dynatech High flow cat, and it says it is universal fit off of www.summitracing.com

My Question is......will it screw with the ODB2, and will I need an o2 simmulator for the new cat?

Thanks guys

it will screw with the obd2 if there is no down stream o2 sensor bung and you dont have the exhaust shop weld a bung on there for it.

a high flow cat is pointless with out a bigger exhaust pipe from there back though.

I have 2.5 inch pipping running from the muffler to the tips....just want to run a new cat....and then 2.5 back to the flowmaster.
