🚗 DNA Motoring Factory Style Catalytic Converter Exhaust Manifold Replacement - OEM-CONV-YW-003 Review

This is a very poor quality product! Machine with mounting flange was offset 0.067 inch. It would crack under his suggestion. The rest of the machine work was done by a five year old Demel tool!

Couldn't find this part locally - ordered from 2 major auto parts stores and each was wrong #disappointing - decided to look to Revain and found - good value no less! When the box arrived (perfectly packaged) it was exactly as described! Mechanics installed - perfect fit! Again on the street!

As a mechanic I have replaced many exhaust manifolds. I usually avoid the aftermarket because they never fit properly on the cylinder head or the heat shield or oxygen sensor holes are misplaced. Tried it for a customer and it worked great. The computer seems happy too. I will try more in the future

My 2008 138,000 mile Colorado started playing. The Check Engine light came on with lean mixture codes and catalyst codes, and there was also loss of power, shaking at idle, poor gas mileage, whistling noise, etc. I thought it was a bad catalyst, so after a few checks, I decided to give this one a go to order. . When I took mine off it had at least 3 large tears, one of which was about 1/8" wide. I installed this with no fit issues and now my truck is running great!

Washers sit flush. The head side has already been sanded properly. The 02 gauges and tailpipe fit perfectly. My engine's performance has improved significantly over my old broken manifold, burned out and clogged catalytic converter. If like me you're short on money and good with hand tools, this could be a very good buy for you too.
