Glass packs are just cheap mufflers. If you mean side-pipes instead of straight, they are expensive & usually have glass packs inside. If it's a newer vehicle, you have to also contend with converters for emissions reasons.
straight pipes are louder than glass packs at first, glass packs have glass wool inside to help muffle the sound, when the glass wears out they get louder, it also depends on the length of the glass pack. if you get glass packs, you can run the car for awhile and shut it down and then spray water in the pipe, it will break down the glass, it might not be as loud as straight pipes but it will give you a better even sound versus straight pipes, I have both and done both.

Yes straight pipes are illegal in north carolina. IF your car or truck has to pass and imissions inspection. But if you don't have to pass imissions the noise that comes from straight pipes is not a big deal. Atleast not it my hometown.
yes they are because a few years ago there was a plot to blow up the president by terrorists planting bombs in the pipes in the president's limo the next time it was taken to be repaired. but they found out about it and since straight pipes are illegal because bombs can't curve they are only straight------------------------------------The above is not correct. Straight pipes are illegal (in the U.S., at least), but they are illegal because of the loud noise they produce and because vehicles with straight pipes usually do not meet emissions standards.

The best way to clean out the inside of your custom motorcycle straight pipes is to remove the pipes and use a cleaning solvent and a rag with a long handled brush.
if u want ur truck to be very loud the straight pipes would be the way to go but if you just want a go sound than the flowmaster 40s would be the way to go but dont get wrong the straight pipes sound great
yes, they are legal, true dual pipes are the best type of pipes that you can buy. compared to "single and a double pipes" which aren't loud at all. of course there are straight pipes which have no cat converters, but those sound like crap. so basically if you have true dual pipes you have the best money can buy
