A y pipe simply merges the two exhaust flows into a single tailpipe. The H refers to a piece of pipe installed between the two and before the y to equalize the flow in the two before they become one. No real horsepower gain to be made there.
the only difference is the price you will pay as long as they are the same series mufflers
40 series
44 series
you will gain some but not alot. and i will tell you why, flowmaster mufflers are chambered so they dont flow very good there just loud. if you want something that flows good were you will gain power but its not to loud than go with magnaflow but if you want something loud and flows just a good if not better than flowmaster go with the flowmaster outlaw series.
keep in mind flowmaster mufflers are chambered. so they wont flow nearly as good as say a magnaflow would. so you will get more HP with a magnaflow than a flowmaster unless you put a flowmaster outlaw series on. its pretty much just a street legal way of straight piping your truck it will flow way good but it will be loud cause there is no ceramic glass packing like magnafow has.
Yes.
the loudest would be the flowmaster outlaw series. its just a straight through muffler with no ceramic glass packing. i have one on my f-150 it sounds way good
what is the difference between N series and C series in nokia mobile phones
