O2 Bung Extender
We do not recommend running without the rear o2 sensor because it could run the rear o2 test and reduce your gas mileage.
Installed the straight O2 extension to help ensure we got no codes on my wifes car from the installation of the ZZP 2.5" catted downpipe. No codes after several test runs and one test drive. As usual with ZZP products this product is quite incredible in appearance and craftsmanship. Heck I wanted to install the angled extension simply because it looked so good, but all I needed was the straight extension. Noticable power increase with the 2.5" catted DP and front PLOG on N/A 3800.
I had replaced stock catalytic convertor with high flow cat. had a p2270 code after installed O2 **** extender and resolved issue
Got rid of the codes being thrown. Would recommend.
Excellent, good delivery and the fitting works as advertised.
Great construction/welds. I purchased this to hopefully avoid a cel when switching to a catless DP. It has been a week, no cel
