ej with a b18b1 4-2-1header, short ram intake, highflow cat with a 2.25inch mandrel bent midpipe with a resonator about 14inches long on the midpipe. What muffler do I throw on there to shut the car up. Currently I'm running a straight through canister and it's loud as hell. I have a super turbo dynomax muffler sitting in the garage would that do the trick?

 

With a resonator it won't be quiet but it will be more deep tone. I have almost that same set up but w/ a b18c, 2.25 straight back to an OEM replacement muffler w 12" Magna Flow Resonator, and it is quiet as can be given the motor set up, basically never get 2nd glance from the 5-0

 

Find an OEM muffler from a Type-S RSX and you'll be golden.

 

Put the super turbo on
My sound dropped significantly after I put it
