Just got done putting on a 4" in 4" out donalson muffler on my straight piped stacks and wow what a difference I can hear again. Great muffler at a great price can't say enough and to everyone that helped me in the process THANK YOU!

 

Glad to hear it went smooth!!

 

The Donaldson save me a butt chewing from the wife. lol

Glad it worked.

 

The truck also seems like it spools up faster just feels better all around

 

Oh yeah...and my wife thinks the truck is loud straight piped out the back. I'm sure I would be looking at divorce papers if I tried the stacks! If I really want to get her fired up, I threaten to run a pipe out of the hood!

 

I showed her that setup on one of the pullers. She settled right down.

 

Well played Sir!

 

My wife was not happy about the straight piped stacks but now she says it ok. Well that's better then getting the look everytime we got in the truck. I get that enough with out the loud pipes

 

I have a Donaldson. She sounds good and not too loud even pulling my 5th wheel up hill. Virtually non-noticeable when cruising and ruck is empty.
