hes not turbo like us
I personally think a straight-piped N/A idi would be extremely loud. Even my rig with the 3 inch magnaflow back when it was N/A was almost too much.
In regards to cab noise, I think some of it has to do with exhaust pipe placement. If pipe dumps out in front of rear axle, it may increase decibels in the cab. My new 4 inch exhaust system exits behind the rear tire (passenger side). And although I know it is a little louder than my magnaflow setup, it's only noticeably louder when I roll down the windows. In-cab noise is about the same.
Cody, whatever floats your boat! Anything is better than the stock muffler these trucks came from the factory with.
