I have RB Headers, the Road Race ones, the Y shaped piped to convert from dual too 1 pipe, then my stock connections, no cats, then the stock replacement peice from monza to goto my monza muffler. As it is right now, this setup sounds so metallic its aweful, i dont like the sound at all, it echos and has a high pitched wistle almost echo`ing in the cheap pipe monza gave me to connect muffler to stock pipes. I have a exhaust guy and i want to know what i should tell him to run from the RB headers right to the muffler so it will sound deeper and not metallic like its in a tin can. Please help! and thanks for your time!

 

if thats what you're looking for go with RB all the way man.

 

Get a presilencer from RB. It goes in place of the cat, bolted to the header.

 

the pre-silencer does help give a deeper tone but it will still be metallic because of the muffler. you need either a good unibody one or the RB primaflow. they do sound amazing and are quiet. if they could flow enough for a turbo car i would use one in a heart beat.
