Review on Enhance Your Vehicle's Performance with the Walker Exhaust 31378 Exhaust Pipe Flange Gasket by Abaraham Duvernot

I ordered this because my catalytic converter was stolen and I opted for a bolt on catalytic converter and pipe (1pc). I installed all the parts in Honda Element 03. Installation was easy for this part. Walker part no. 31378 is for downstream (after cat) and part no. 31531 is for upstream (after distributor). Downstream was fine, upstream the seal/donut needed cleaning to make it fit. Also the upper part is not the same as in the photo. However, this part is correct. Overall very happy with the details.
