Had the Magnaflows(#11225) installed today by a reputable shop and while I was there also had them remove the resonators sounded really nice had a nice rumble but more cabin noise with the windows up then I would have wanted but I could have lived with it..Once I hit the highway and floored it... WOW the amount of flatulence from the exhaust was horrible after letting off the gas sounded like an exhaust leak but it wasn't,so I returned back to the shop and was informed that it was due to low back pressure and the abrupt angle on the h pipe..Not sure how true this is but it sounds fairly accurate/logical...
So back in went the resonators..Sounds good a noticable difference from the stock mufflers,the sound is more noticable at lower rpms/cruising speeds..All said $180 for mufflers and resonators removed and another $50 to have the resonators reinstalled leaving the exhaust alone after this..Next mod will be the K&N typhoon intake..
Just posting my experience.. Later
