Ditch the factory gas particulate filters to increase power, save weight and add a throatier more aggressive tone. Our design process started with 3D scanning the entire exhaust system using our CREAFORM 700 Handscan so that we could make a complete Solidworks 3D model of the exhaust. We then designed the exhaust and fixtures using that model so that the exhaust fit perfectly to OEM standards. After multiple revisions for sound and dyno testing we settled on using a one piece mandrel bent over axle pipe that goes straight into the free flowing part of the OEM PSE exhaust and a secondary pipe TIG welded to the main section to make a Y configuration to utilize the quiet side of the PSE exhaust when the valves are closed.
These Over Axle GPF Delete Pipes will bring out a stronger throatier tone from your 4.0l flat six. This is a mild but noticeable increase in overall volume over stock.
This part works best when combined with either one of our cat back options. With our Valvetronic X-Pipe it made tons of low end power, +14 whp and +32ft/lbs of tq at 2400 RPM, and maintained good gains all the way up to redline with +12 whp and 8ft/lbs of tq at 7500 RPM.
