SLP LM1 or Flowmaster 10's

I'm running straight pipes right now, and have bee for about a year.. It's loud but more of an annoying loud, it's also loud on the inside, so I'm wondering which of these two mufflers would sound better.. I want a loudness from them but not annoying loud like straight pipes.. I have stock mid pipe and would only be able to go catted x or h due to emissions.. Thanks

Yeah that sounds pretty good. Does it sound raspy in person?

A bit But bot really, Too me it's almost perfect, it's not loud unless you want it to be, it realllllly starts to growl at half throttle, wot it screams, but if your just cruisin and takin it easy, it's not loud but you still hear the signature sound of the SLPs

I'm a fan of the FM 10's on the 4.6L but really love the loud, aggressive sound of BORLA's XR-1 Multicore mufflers.(Multicore, NOT the Sportsman)

Not really a lot comes from the rear seats but windows up radio on you won't hear it. But windows up no radio isn't bad. And depends if you have cats or nit
