It helped some in the mid range and top. Off the line feels the same. But it sounds better than the typical secondary cat delete and mufflers. Or secondary and resonator delete. It sounds less like a truck and more like a performance car in my opinion.

The car runs on 91. I just like 93 to help reset timing. As these cars can suffer the same timing fate as the ISF's. Rr-racing had a writeup on it if you go over there. But you can reset it and just toss in a good brand of octane booster and good 91 (no walmart,kroger,Costco, or Sam's aren't good 91). She should pick up a bit. And hopefully maintain that once you go back to good straight 91.

Did you guys have to get extensions for the oxygen sensors when you installed the X force exhaust and headers on the GS460?

For now I’m going to keep the original cats on the headers and run the ISF X Force cat back, Injen CAI, ISF TCU & Loi’s custom tune.
hopefully the combination of all those together will make it nicer to drive with more pull and better sound. I know the cats off the headers muffle the sound a bit but I Also think the addition of a true X pipe will bring some more sound out of the engine since the original set up is a wishbone off the headers and that kills the sound since it goes to one pipe then splits to 2 mufflers
