OH no my friend there is just as much cackle with the M55. Their designed the same, both straight through. they sound alot alike. Where are u planning on getting the catback from I cant find it on ford racings website?

i wouldent go and say that one is louder then the other. i would say when you get as loud as they both are, it dosent matter. because it's so damn loud you cant hear shiat anyways.

let's just say when you race people and they have to have there window up your car is loud. i raced 1fast 99gt one time and he forgot to roll the window up, and that lead to him trying to cover his left ear and him missing a shift = me winning

The M55 tho at least has a little bit bigger muffler which will counteract the noise a little bit and the cackle. Yes they are both designed straight through but LDM's 1 cackle like the most on any mustang I've ever heard. IMO it gets obnoxious (not spelled right) after a long time.

Yeah hey its all good and its ur car man just trying to help. The guy I knew had the M55 on his 03 said he used to get pulled over all the time before he put cats on it. My friend and I literally thought he was running open headers when we heard him. You know its some loud exhaust when u can hear his exhaust from behind you.

ya i that would be loud and i dont have cats either so ya since there both pretty similiar in how loud which one has better sound i kno the m55 is cheaper but is the loudmouth better performance wise ive looked up info on it but there is no better way to kno then personal experience

my personal choice would be the M55, i run straight pipes on my 67 with a 5.0, so i like it loud.

ok guys new problem here they dont make m55s anymore so i guess i need new ideas here i am now lookin between loudmouths bassani and magnaflow and i am startin to think that loudmouths might be too loud with o/r x pipe though i do want loud but i dont want it to be as quiet as mac or borla or that kind of sound...i kno im picky but that wut u gotta do i guess but if i can hear your thoughts on these that would be much appreciated thanks

they're all names that have been proven to provide power and last. Just gotta go with the tone and the price
