On a completely open exhaust system: If one wanted a loud clear overrun crackle from the exhaust but not an excessive booming low down bass sound around 500-2000 rpm, would it be adviseable to:

Place a small muffler on the central section of the exhaust, or place it at the end?

 

well first of all we need to know what kinda car we are talking about here

 

We are talking about a car with a naturally aspirated 3 litre V6 engine and a straight through open exhaust system. I doubt the make makes a difference.

 

well knowing it is NA makes a hige difference because then i have to ask...why do you want a straight through exhaust. You are not gonna see much of a gain from removing the cat, so why do it.

However if you wanted to muffle the sound a bit the best thing to do is add a resonator on the middle section of the piping. However i still thinka high flow cat would be a better option
