No it won’t hurt the performance enough to matter. Yes, it will quiet down the whistle a lot. That the main thing with these trucks, it’s the turbo, it’s so damn loud lol
That has to do with the way the tunes are for most deletes. I still get turbine whine but it’s significantly less. Interestingly though, the turbos do a lot to reduce the exhaust sound pressure level, so with more of the turbine exposed, there is less whine and more note.

Either case, spl does go up after a delete.

So this site "unlimiteddiesels.com", is it a legit site? Has anyone actually ordered anything from it? I can't really find any reviews aside from their on site "testimonials". There's another site called "unlimiteddiesel.com" without the "s" and it has tons of reviews but doesn't sell delete kits. Just want to make sure it's not a scammer site like several out there.
