Im going to do a turbo upgrade and I was going to go with the Garret GTP38R but I have been told it is VERY loud. I love the turbo whine but if it is real real loud it could annoy the crap out of my family pulling the 40 foot 5er for a few days at a time traveling. Any opinions on this or different turbo options?

I pesonally dont think it is any louder than stock. It sure is not as loud as a 6.0:
