I have 06 sedan a.t. with a hks muffler, it had a lot of drone from the 1500 rpm-3000 rpm range. So I recently added the hr y-pipe and while i was doing it i installed a less restrictive magnapack resonator for the mid. i still have drone around the 2000k mark but its pretty much gone around 3000k. So a knowledgeable friend on this forum told me if i take the magnapack resonator off and just replace it with a str8 pipe that i will eliminate most of the drone, b/c the air will flow better. What do u guys think about that? Has anyone had an experience like this? Thanks for any help fellas. Sorry bout the long question

 

pretty sure removing a resonator will add drone :-/

 

whoever told you that is retarded and doesn't understand drone

Sedan is prone to drone because of the trunk space. Sound/noise vibrates around in there and comes through the cabin. This is the reason that the Sedans have such a different midpipe.

 

I was thinking it would make it worst also. I'll just deal with it b/c it sounds so dam good at wot. Tollbooth how was it when u added ur HFC. I thinking of HFC's r the test pipes that motordyne is coming out with. What u think
