5 inch with muffler or not
I was just curious as to whether or not a muffler would need to be used on a 5 inch exhaust system. Im going to install one soon on my 99 dually. Since I live out in the country, offending the neighbors is not a problem. However, i was wondering if the small amount of back pressure from the muffler would help out the turbo. I have heard that a small amount of back pressure is a good thing. Any help in this matter would be great.

I have never heard that diesels need back pressure. No muffler will be louder only. No performance gains (from what I hear). Why 5" and not 4"? I think 5" is for over 500hp. My brother has a 4" with no muffler. It's not too loud inside. Very loud outside.

I thinking you might be right, ive always been a straight pipe guy. However, im worried that the in-cab drone might wear me out. The truck already has a straight made from the stock exhaust, and the in-cab noise can be wearisome. Im still up in the air about size, a 5 inch sounds downright angry, but a 4 inch sounds good also. But you know what they, "Everything is bigger in Texas."

The 5 does have some wicked drone while towing, but I really like it! On long hauls I wish it was a bit quieter than it is, but 99% of the time I love it! The louder the better! Im sure In 10 years I'll have a different outlook!

I live 20 miles south of Lamesa. Im thinking the 5 inch just would be so much better with the straight pipe, so im going for it. My horses are gonna kill me over the noise!

Well, I used to have a 350 ci Chevy with 3 inch straight duals with 6 inch tips, they were fairly loud. I handled them, so i think ill be able to withstand the nasty growl of the 5 inch.
