Engine/Transmission (1998.5 - 2002) 4 inch exhaust...

[THenningsen]

The way I understand it is that the stock down tube that comes out of my turbo is 3. 5". Therefore, if I want a true 4" system, I need to replace the tube. Who makes such a part. I want to go with a stainless 4" system. Any recommendation? Who is the best company? What about the droning? Thanks.

YUP, Rip has them - here's a thread on one of his system installs - and it includes "drone prevention":

Unless you you are adding a significant amount of power, the 4" system is not necessary. It only adds a lot more noise. If I had to do it again, I wouldn't do it.

I know I will make a lot of friends saying that!

I was concerned about noise level too when I planned my injector/4 inch upgrade - but the setup Rip and crew installed is nearly identical in noise level, right at the tailpipe, as compared to my OEM setup. I figure I should be slightly over the 400 HP level - so maybe I'm not high enough yet to be in the "significant power" range!

Rip has great products, no complaints here.

There are a number of good systems out there, but you won't find any one with better customer service than Rip. I got a good price on the Banks system & have no complaints. Like Gary, I found no significant change in sound volume in the cab. The tone did changed a little though. The most important performance effect for the 4" pipes is the control of exhaust gas temperatures under heavy load.

Rip's is the way to go.

And why do you own a diesel if you want a quiet truck

Also I saw a significant EGT drop.

I like the diesel, no, I need the diesel to pull heavy loads, like my neighbors Duramax!



As you can tell from my signiture, I own a 4x4, 6 speed. I love this truck, but wish it were as quiet as a hybred. It is loud! A 4x4 sits up higher, which muffles the sounds less than an lower 2 wheel drive truck. I have the full ATP wrap system for the valve cover, exhaust manafold and pipe, turbo and oil pan. I also have the hood insulator by ATP wrap. The 6 speed is conciderable louder than the auto trans too. I did not have my guages installed before the 4 inch exhaust was installed, but I am sure that the temps are a little cooler now. I do know, however, that the exhaust is conciderably louder than before. This is not good when I leave for work at 5 in the morning, or pull out of a camp site early in the morning.



So there, I feel better now.



Can't talk, gotta go!
