    Actually I think the FJ kits will get released first.

    Then the 4Runners.

    Will get a better graph for you folks comparing low end less than 4k rpm. The following had one of the baseline runs for comparison but late to WOT. Please ignore everything before 4200 rpm

    This exhaust sounds like a beast without the mullfer. It sounds like a 370z with aam short tail or kind of like a gtr. It turned a lot of heads today at the muffler shop. Customers ran to the street just to see me take off. It surprised all the hot rod and ricer guys.

    If you are running full URD headers and Y pipe and no muffler, do you have sound clips? My truck ain't loud enough for me.

    We had a few to many complaints about resonance from the system. So, stopped shipping it until we can sort out why it works very nicely on some trucks and not others.

    We have a revised version in testing and if all goes well will release it soon.
