I would just cut it out and have a piece of pipe welded in...but that is just me I guess. An o2 Sim just deletes the code for the converter not being there...so he would need to just have the code deleted for good if he ever got a tune. They do make handheld programmers for the GXP though...not a chip...not a tuner but it still works...like I said. Not hardly any aftermarket support for the LS4 cars minus catbacks, downpipes, intakes, and plug in play tuners...oh...and rockers...but that is about it. Anything else is going to be expensive unless you spray it.

Oh yeah that's right, I forgot he was running the LS4 not the 3800. Oops. I thought he was running the series III. Yeah I know they make the handhelds, but I couldn't tell if what he was talking about was one of those, or one of those "chips". He'll have to post a link to what he's looking at.
