Thanks man. I found the resonator that I was gonna use on my last project that I didn't get to. I'm running 3" tailpipe. Volume and sound are excellent, it's those dreaded few areas; 1300- 1750 rpm and 2500- 2800rpm. After company leaves I'm gonna get on it...……...

An additional update, as I venture into the engine side of tuning, the exhaust note is tightened up considerably, while yes you can purposely lug it and V4 can get atrocious as well cleaning up the tune has been the best thing yet...………..

Well guys- pleasant update; I made a J- pipe/ Helmholtz resonator tube because as you call all remember I had this lazy sounding drone. So- the J- pipe, it's cured everything; tightened up the exhaust note, and best part, no more drone in those dreaded areas. Not embarrassed anymore to roll in at 900 rpm up the subdivision main drag lightly applying the throttle. So what I've concluded; most every aftermarket muffle will have that lazy drone at certain rpms, and the cure is a J- pipe, I swear by it- where the Dynomax and other resonators failed to help, a Helmholtz/ J- pipe is the ticket...………..
