I'm about to do the exhaust on my 2009 a5 rt, got a quote of 550 from a refutable shop to do a custom 2.5 in. cat back with flowmaster 44's and no resonators. I was completely happy with this until I watched a video of a new scat pack with a muffler delete with the resonators still intact. Hands down best sounding Challenger I've ever heard. What do you guys and gals think?:4-dontknow: Has anyone done this on an rt? I'm sure it will be louder than my current plan but I'm not complaining, My guess is that it will be better for drone since it's an a5. Thanks in advance.

Most auto trans owners experience drone with a resonator delete. For a more comfortable ride where you don't rattle the fillings out of your teeth, try keeping the resonators and delete the muffler.

I deleted mufflers and kept resonators, the sound is awesome and nooooo drone
