Lemans answered it already for me, but i have the Dinan midpipe and rear and it is the best sounding car i have ever heard plus there is no drone at all and the power increase was awesome, best mod i did for sure.
also if your getting Dinan software they have software for the midpipe so if your not gonna get the Dinan midpipe and rear then don't get there software go with a different company
the Gintani is nice but i believe it has drone and there is no way i could stand any drone. the set up i have sounds exotic above 4k and nice and deep below 4k and has no drone and awesome power. best of all worlds
i have all the products you listed by Dinan and couldn't be happier and my dealer doesn't say a word about warranty
good luck with your new car
