G37 sedan Art Pipes W/ Top speed Exhaust

Any members on here running a G37 sedan with art pipes and a top speed pro 1 exhaust?, I have a top speed y pipe as well. I Installed some art pipes and the rasp is really bad! Does the rasp muffle down after a while?, thanks!

I had RTPs w/a similar Y-pipe connected to my Top Speed on my sedan and went back to my oem Y-pipe, the Y-pipe is the culprit, and that rasp was NASTY!

If you can take your Y pipe to a shop and have them cut off the large 3" collector and replace w/a 2.5" reducing cone/flange that should decrease the rasp significantly or maybe get rid of it all together. That's something I've been wanting to do, but life keeps getting in the way

thanks for replying, I might end up adding a resonator to my aftermarket y pipe to see if it helps.
