I currently own a 06 IS250 and i was wondering what i need to get in order to just get that very deep and smooth sound. I dont need any performace added just the sound because IS250 is already exteremly slow so i dont want to add any extra performace to it, however i just want that deep smooth sound. I was wonder what i need in order to get that and im trying to save as much money as possible so can anyone tell me what i need to get?? Just mufflers, Just intake, or do i need a full exhaust in order to get that sound that i want?

Thank You very much

 

just get some maganflow mufflers welded in the place of your stock ones

 

Looking at doing the same plus new tips...how about removing the secondary cats at the same time?

 

then you begin to get into in-cabin resonation territory
