Hey I have a 2003 gt with a flowmaster exhaust and I was wondering if an o/r h-pipe would be too loud for a daily driver, or if there is a large amount of droning at higher speeds. all help is appreciated.

 

Drowning, yes probably with the flowmasters, too loud for a DD, depends on personal preferance.

 

Your car will be heard from two blocks away just by driving normally.

 

off road H's and flows sound tinny and hollow. drone is considerable at high loads and low rpm. I really couldn't take the drone after a while and switched to a non-resonator type muffler. Much happier now.

 

What about if he ran a catted h-pipe...would that be a more tolerable solution??

 

i have a daily driver mac offroad h and flowmaster 40's........doesnt bother me loud as hell tho if your not in a high gear........click my 35th link for a soundclip its at the very bottom of the page

 

flowmasters drone like a bitch...i love the sound outside of the stang but with my buddies o/r x and weld in flow 40's it is headache drone inside...he is switching to magnapacks to see if it helps

 

ya it will help big time.. I had Borla Stingers with Offroad X, and it gave me a headache and my ears would start to hurt after a while, so for HEALTH reasons I switched back to catted x and its a lot better... but I do miss how loud it was and scaring people and setting off every single car's car alarm when I go by, but its my daily driver and I couldn't take the sound, it got to the point were Id drive to work with my father until I got my catted x pipe on lol..

 

Drone sounds horrible around 2-3k but other than that it will sound sweet and not too loud i think...

 

Dude, he really needs to go with something else besides magnapacks. They pop like a damn popcorn popper. My LM II's sound MUCH better than magnapacks in my opinion.

 

lol are you serious? nothing would stop me from driving a loud *** stang even if it gave me headaches...you must have sensative ears...i mean yea its annoying but not that annoying to not drive your stang

 

yea...he still doesnt know...but its not like it matters...he still needs 460$ to buy some rear tires for his black bullits...and then buy headlights, grill, delete, etc...i think he wont be gettin a new catback for a while

 

its not just that I get serious MIGRAINE headaches.. were I throw up, get dizzy and get blurred vision it sucks... only way I can get rid of them is if I take a nap..

 

ditto. I get em too. Driving home from work nauseated with a blinding headache and a loud interior resonating exhaust sucks big hairy donkey nutz. no bwaynoh.

Some magnaflow's, borlas, bassani's or similar muffs will sound really good with or without cats (cats are milder and you SHOULD use cats just on principle).

 

I have had my Flowmaster's for about 10,000 miles now and to be honest, the drone has gotten quieter, though it is still there. However, there is always the option of adding a resonator...

 

yea my friend gets those but he deals with the loud drone somehow

 

magnapacks = stingers > * end of stroy...

 

does that make sense?

 

other than misspelling story yes.. it makes perfect sense.

 

It is all preference. I have a MAC O/R Prochamber on my car as a DD. It is loud, but not too bad. Luckily my LM II's dont drone with it too much. It drones around 1700-1900 RPM, but I have 4.10 gears and I turn about 2400 on the Highway and it has no drone at that RPM. You will notice a power increase on the but dyno.

 

TClark: what he said /\ /\ /\ i cant type when im tired

 

Thanks for all of the help... I'll probably get the o/r h-pipe....would 4.10 gears help out the droning in high gears???

 

haha..no gears have nothing to do w/ sound

 

Gears in a sense help out with drone. With stock gears, you will be turning about 1700-1800 RPM on the highway (65-70 mph). 4.10's will bring you out of the drone rpms (1700-1900) while on the highway. Something about those rpms creates a low bass sound frequency that is referred to as "drone." Imagine if you were listening to a subwoofer at low frequency. The low frequencies are much harder on your ears and "drony" than when if were at a a higher frequency. The 4.10's cause your motor to spin at a higher rpm (on the highway) which creates a higher frequency of sound.

 

Or you could just go faster?

 

 

so the higher the rpms the less drone?

 

Not always since the other factor is load. For example, at slight throtle, I get the same drone I get at 2k rpm at 1k rpm. Generally though, anything above the 2k mark will pretty much be drone free.

 

drone is almost universally gone by 2200rpm. I've had lots of exhausts and they would all drone a little but none above 2200rpm. So yeah... 4.10's will keep you out of the drone zone since it's pretty hard to be under 2000rpm but still under load. Avoid high loads + low speeds + high gears. That combo is the basic formula for drone so if you're at a low speed in a high gear, downshift.

 

thanks for taking the time to think logically about what i was asking and answering it....
