Well....yup, your right it isn't that loud and I run mine like that (straight that is). Wasn't the point I was making, or intending.
My comment refers to the trend I've noticed with customers who all want that narly straight pipe sound until they've driven it for a while....on the road....highway....and they feel the need to tone it down a little. We've done some fairly quiet, very fast diesels.
Also found that for stock motor performance a full on straight pipe does nothing for perceptable performance whatsoever compared to say an NRP stainless system with two resonators. How this compares to a standard Rover system I have no idea as I've never used one.
Once you start playing with the IP then you should think about modifying the exhaust.
