You could have just said:
Warning, the following product is for mature audiences only. Driver discretion is advised.
Just kidding. You make a really good point. I think most of the users who've read this entire thread have (hopefully) ascertained the level of danger inherent with this type of mod.
As stated earlier, you can attempt to combat higher EGTs by installing a well-breathing filter. My personal recommendation would be the removal of the CAT and DPF (which I know a lot of us are already researching). A better exhaust should take nominal temps down by at least 150 degrees Fahrenheit.
While we're talking about DPFs, the life of said product shouldn't be diminished by any marginal amount at best. Plenty of gassers are out there running FAR too lean and aren't plugging converters. The same can be said for any diesel truck assembled prior to the gov't diesel exhaust restrictions. I haven't talked with any drivers who've plugged a CAT while dumping more than the factory spec of fuel down the pipe.
I understand the openings on a DPF are smaller, but I think this is still a valid deduction. Whats more, most of us in the "tuning/performance" crowd intend very seriously to remove these devices altogether.
As for the drive train. -Personally, I can't say I'm very worried at this juncture *knocks on wood*. The small addition of power given from this device shouldn't be any more stress for the drive train components than a stock 3.0 with a full-load limit trailer going uphill with a strong headwind.
A good way to ensure your power additions will play nicely with the vehicle is to remove weight from the vehicle. -Remember, every little pound helps! Oh, and your MPG will improve too, with enough dead weight missing that is.
Thanks for bringing this to the table no-blue-screen
