I just got a 07 gt and would like to put some different mufflers on it so my ? is I have some stock mufflers off of a 09 roush 427r would they sound any different then my stock one's?
i've got mid mounted pypes m80's. not sure about the fitment of the mid muffler system now, but when i did mine all i read about was how it didn't fit well, so i bought the mufflers and had a muffler shop bend some over the axle pipes and welded some tips on. love the sound
