I've decided to quiet my car down but am still wanting to keep my true duals. Right now I have the 18" Flo Pro Twisters and looking at getting the longer 23" mufflers along with Dynatech cone inserts you put in the header collector. How much quieter would this make my car? The main objective is to reduce interior drone to that of a Flowmaster catback or thereabout.

do they come out the back, if not do it....then it will be less loud

I think cone inserts will rob power, could be wrong. what I would do is run chambered mufflers or/and runn td's all the way back.

Anything that will disrupt the flow of exhaust will rob power. You could change out your mufflers like you have stated, but anything that is a straight through design such as a bullet is going to be loud.

If anything look into Stainless Works, they have a chambered turbo muffler that will bring the sound down, yet still sound boss when your cruising and going WOT.....

No. If I could I would and run dual Flowmaster 40's. But I still have the Panhard rod back there, and I don't think there's enough room to run a 2.5" pipe over the driver's side of the axle. I also don't like under-the-axle setups. All the ones I've seen looked kind of shoddy.

install some cats and some longer bullets, but they won't quiet it down nearly as much as full size mufflers so search for some that will fit.
