Which is only reasonable.
If you can't afford to fix it, you can't afford to modify it.
There's no reason that GM or any other manufacturer should be on the hook if you start doing things that create greater stress on the bits than what they've tested for.
Either you'd better be damn sure it's not going to blow up, or (in the BMW world) you'd better pay the premium for Dinan's stuff and get their warranty.
Dinan typically does good stuff but they price it to chase away the cost-sensitive buyer. I'd love to have a set of his $8000 headers (okay, with a little careful shopping you can get 20% off that) on my E39 M5, but at this point that's money that's better put toward finishing up the project cars (the freshly-painted-but-otherwise-naked '65 Mustang convertible having now joined the freshly-painted-but-otherwise-naked '64 Country Sedan in the garage; the '89 Mustang track car is awaiting a bunch of wiring and a quickie paint job of its own), or an enclosed trailer for the track car, or an airplane, or finding one of the 44 (maybe less, by now) Merc R63s extant in the US, or a CTS-V wagon should GM decide to see the world my way...or, at the rate things are going, three tanks of gas for one or more of the above.
