I currently have an sports muffler... If i replace that with a hotdog.. will it sound pretty good?
Anyone got any better ideas??

Also will it be defected or pulled off the road quite easily? As it could be too loud???

if you are only running one muffler and you replace it with a hot dog then yes it will be way too loud, i ran 3 hot dogs in my datsun for abut a month b4 i got sick of the obsurdly loud noise, mates said they could hear me comming from a mile away, just stick with a good free flowing sports muffler shouldnt make it too loud but should still give you a nice rumble,
