My g37 IPL has really annoying rasp and drone in lower rpms.
What size vibrant resonator would be good to remove the rasp i get around 2.5-3rpms? And will it help if i put the resonator end of my Y pipe or at my Axle back? I have meistershaft mid pipe, aam axle back. I dont want to cut my mid pipe but i am willing to cut my axle back or Y pipe.

 

Please stop using 'k'. You're doing it wrong. You post title sez your car has a loud rasp between 26,000 and 32,000 rpm. That rasp is the sound of internal engine parts ricocheting off of other engine parts and fenderwells. Very small parts.

I suppose you mean between 2.6k and 3.2k rpm.

 

damn.. your car can go up to 32,000 RPM?? that's more than a rocket ship!

 

Gthaus mid-pipe has no resonator if you want to eliminate the "rasp" you can try putting the stock mid-pipe back.

 

Op might have the best roll racing car known to man
