Fully Bolted + Juiced!
As many of you know my X has a custom 2.5 inch exhaust system with a downpipe of the same diameter. I am also currently running catless. The problem I have been having is that my resonator self destruct internally every 4 to 5 months due to excessive back pressure. What can I do to decrease some of the pressure or what other options do I have. The resonator length I am using is 27 inches with oval entry and exit to decrease sound/droning. Any help/suggestions?
