Hi all,
If you had a twin 2.5 inch, and compared it to a twin 3 inch, same headers, same cats, same design mufflers/resonators what could be expected in terms of decidel difference between the two?
I have been told the twin 3 is much deeper.
I have a twin 2.5 on mine, with headers and high flow cats, but since my cam and heads went on, it became much louder ( a good thing) but it got even worse with the drone (its a A4) between 1500-1900 RPM.
I am thinking of going to twin 3 inch, with bigger mufflers/resonators up the back to eliminate the drone, but dont want to lose TOO much of the volume as it sounds pretty tough.
Also does the merge or balance pipe effect drone at all?
Thoughts people?
