how to quiet down 3 inch exhaust

im already running 2 layers of dynamat and 2 layers of just throughout the car, including the trunk.

and i love the sound, but it gets old afer a few hours tooling down the highway at 3000 RPM.

a good example of how this car is used:
later today, were packing up the trunk, and taking the 3 hour trip to eastern tenn. from there, well hit kentucky and VA tomorrow, and be back here for church on sunday.

its going to get old pretty quick.



so what im hearing from a lot of guys is to put resonators in the system. i have a spare set of dynomax race bullits from one of my track cars. do these do the same as the glasspack or resonator?

is a glasspack the same as a resonator?

i also read the suggestion somwhere that i could use a restrictor plate at the header collector that necks the system down to 2.5 inches at the plate, and that would drop noise levels considerably. does that sound right?

anyone wanna trade me a 2.5 system for a 3 inch?
