Hey guys,
I want some more "oomph" to the sound of the exhaust and at the current setup, many people would say it's really loud; but, I feel that I'm just used to the sound of the exhaust. What could I do to make it louder? Would a primary cat delete do the trick or even high flow primary cats?
Any input would be appreciated. Thanks.

Here is my current exhaust setup on the dyno:

 

When people say it is loud, are they speaking from hearing it from inside the car or outside?

Headers would make it 2-3 db louder (10db=twice as loud)
hi-flow cats may be 2 db depending on what cel is currently in the system
adding a straight through muffler may also make it louder; at certain low frequencies
adding glasspacks (which is essentially a specialized straight through)

 

what changes have you made to the exhaust ?
