I think King D is running straight pipe. I know there are a few for sure. I doubt very much that it would decrease low end power. I am debating on what to with mine as well. My problem is I want it to be loud sometimes and quiet others. I guess you can't have everything.
Yes Edge juice. Guages are recommended but not 100% necessary. A little common sense goes a long way. I would guess that probably less the 1/2 of people who do upgrades actually have an EGT guage. I am working on a very stealth looking install but I am waiting to see what the attitude looks like first.
Don't forget, for Gm to deny you warranty they have to prove first that you have a power adder and second that it actually caused said problem. A guage doesn't prove you have a power adder. It just shows that you are smart and want to watch your EGT.
I promiss you won't regret getting the Juice. It puts a smile on my face everytime I drive it.
I've been running straight pipe for two years. Diesels love unrestricted flow, however you accomplish it. Remember, diesels don't have a throttle plate or vacuum like gassers. It is designed to be free flowing. The maf sensor detects more airflow and tells the ECM more fuel... but it's not necessarily translated into more power as the paramerters are still there that control power level and rpms. The add-on power boxes take care of that part.
The benefit is cooler egt's and possibly slight power gains.
HEHE i have a banks exhaust system but it wasn't loud enough for me so i straight piped it. so i now run a 4in straight piped exhaust and god does it sound good. lol . when i put the pipe on it put my truck into limp mode for the first time so it didn't loose any grunt.
