CLUBSFIT

Hi everyone, I know in the past everything was negetive on shorties, but w/an off road mid pipe, it seems like the JBL, or BBK tuned/equal length shorties have to make sense?? Can someone who installed shorties w/an off road pipe, please come clean, and let me know if there were any gains?? I just dont want to purchase another mid pipe to bolt up to long tubes. I am running out of N/A mods, and still have warranty left before I get Whippled..

Thanks in advance
