Best is to use test pipes or LTH's to prevent any type of restriction or possible catalyst melt down. However, is it worth the loss of SC kit potential in terms of power and possibly boost levels?
I'm waiting to see what GTM can accomplish with the VVEL test tuning before I install my LTH's or just say frig it and install them anyways and live with lower power levels because of the VVEL timing and lower back-pressure.
Today I'm leaning towards frig it and install the LTH's anyways and live with what will be, will be in regards to the power levels on the stage 2 kit. ........ if it ever gets delivered .... lol
Good thing I'm patient
