Looking for feed back on going from 4 inch staight exhaust from turbo back is what I have now on my 98.5 dodge cummins to 6 inch stacks. Was wondering about the difference in noise levels inside the cab {quadcab} if it would increase alot or a little, any opinion would be helpful Thanks

 

with out a muffler its gonna be loud , its cool for a while then gets annoying

 

I know whay you mean about getting annoying guess I'll have to put a muffler on

 

I love the sound of mine i have my window down in the winter to hear it some times
its all about how you like your noise level

 

i love the way both of my diesels sound i would say do it all the wayhttps://www.dieselbombers.com/images/smilies/tu.gif
