there was one member, 4everkidd, who removed the mid muffler/resonator. he said it sounded a lot louder and just what he wanted. if you search, you can find his thread w/ a photo. i've too considered chopping the reso off but i'm too worried about the increased drone. when i contacted borla, they said removing the reso would def increase the drone.

Has ANYONE ever gotten pulled over in SoCal for noise? I'm hesitant to punch it

I emailed Borla support about the drone, quoted my receipt number and they sent me 4 venturis for free. They look like this:

I raised the back of the car, detached the muffler section and used a mallet to knock the venturis into the axle-back section of the exhaust. Borla recommends you tack weld it, but so far I have had no problems nor rattling without the welding. Put the mufflers back on and you're all set. They sent me 4 venturis but I only needed 2. It's VERY straight forward, even I could do it! Note that it is a very tight fit (and it should be, or else it'd rattle), you won't be able to get the venturis in using barehands. Think "virgin on wedding night".
The venturis are apparently too far along in the exhaust system for the restriction to have any impact on performance, and my butt dyno verifies this. It certainly removes the "boominess" of the droning, but still retaining the HP gains, beautiful WOT sound and V8 rumble at idle.
