Im a new member here and i am practically obsessed with mustangs, but i had a few questions. ive been doing a TON of research and im trying to find the LOUDEST, DEEPEST, MEANEST exhaust combo for an 05 gt. My buddy has an 88 LX 5.0 with the flowmaster american thunder and sounds AMAZING, but from what i have seen/heard online the 05 flowmaster models just dont sound nearly as loud. From what ive been reading and listening to im a fan so far of the SLP Loudmouth 2 (whats the difference between LM1 AND LM2?), and also Borla Stingers. i am also looking for a nice H pipe, from what ive been reading H pipes are louder than x pipes, but ive heard a great combo is borla stingers w/ a bassani catted x pipe? i am a little confused and i just want the loudest meanest exhaust! Also, do headers add to sound, and whats the difference between shorty headers and long tube headers. Last, whats the difference between catted pipes and off road pipes (why are they even called off road?). Ive been tryin to find these answers but cant find exactly what im looking for!

THANK YOU!

slp loudmouth 2 are definately the loudest in my opinion, h pipe definately has the deep mean v8 sound to it. catted pipes and off road pipes, well off road usually add more performance and sound meaner than ones with cats do, but if your city or wherever you may be is very restrict on car emissions and inspections then you may not want to go that way because cars dont pass without cats if the inspector knows what he is doing. and yes headers add to sound, atleast long tubes do, my friend has some jba long tubes he just put on and it definately added some to it. but then again long tubes also, are not emissions legal.

Long tube headers, cut the cats off the stock h-pipe, connect that to the headers, then slp loudmouths out the back (or do borla, just so i can hear it ) and you will have it pretty loud indeedy
