Hey guys I'm sure that this topic has already been covered but I was wondering if and intake will make my car more audible at higher Rpms I have 3 inch straights from cat back to 2 high flow mufflers and I get a great throaty low end sound but as soon as I hit 2.5 to 3k it just gets quiet and sounds like the stock exhaust again

 

there is a intake for the 2.7 by S-flo. claims it increases hp but i have no idea if it makes sound deeper or not.

removing the resonators will be your best bet if you havent done so already. the turbos chargers absorb alot of the sound.

maybe downpipes will make the sound deeper.

 

I just added a Billy Boat downpipe kit and I don't notice any more volume, although the guy who installed them said he could better hear the turbos spool. The resonators were deleted by the PO so I cannot advise if that helps. Overall, the car does not have a loud exhaust and I prefer it that way.
