I have a 2006 Lexus is350 with ppe headers+ x pipe + custom dual exhaust mated to cherry bomb glasspacks + Invidia Q300 mufflers(no meow meows), I also have valves after the glass packs for when I want to be obnoxiously loud.
the exhaust was way too raspy and high pitched with just the Q300 mufflers so I welded in 2 glasspacks(red sections) which made it sound a little better but it's still too raspy for my liking.
so my question is what mufflers can I replace the invidias with so that it will have a deeper growl like a v8? I'd like the muffler to have similar volume and no drone like the q300 but deeper sounding.

My son has AutoTech/Magnaflow mufflers on his 350, sounds pretty good. No cats, has X pipe....kinda loud sound, but not raspy.......low tone rumble.
