These downpipes are the best you can buy at the best price out there! They can add 30+whp with tune adjustments by eliminating the restrictive cats and significantly reducing backpressure and by increasing the pipe size from the stock 2.25" to 3", that's almost an 80% increase in flow through area. the quality of these pipes is superb made from stainless steel 304, hand mandrel bent and expertly TIG welded with backpurging to get the best material and the best welds. The flanges are CNC machined and fitted perfectly to the pipes so the airflow goes perfectly smooth inside. The exhaust note also gets deeper and really makes you smile when you hear it. Your going to love the power gains and slightly more aggressive exhaust note!
