Review on πŸš— DNA Motoring Factory Style Catalytic Converter Exhaust Manifold Replacement - OEM-CONV-YW-003 by Jose Strong

Revainrating 4 out of 5

$1,000 less than the factory and after a little cleaning it fits perfectly on my 2008 Colorado L5 3.7L

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.

Pros
  • Catalytic Converters
Cons
  • Functionality
