What kind should I get for my Cobra? I want the very deep, throaty sound that identifies a mustang coming from a block away. A sound that "hits your chest" at idle and cruising speed. I can't remember if it was the Flowmaster 2 chambers that give the classic tone. I am considering a few options:
- flowmasters
- magnaflow
- SLP loudmouths
- Mac boom tubes
- bassini
- others?

then I don't know if I will replace the H-pipe and cats with high flow units and mufflers or just replace the mufflers. There is a substantial cost difference in those two options though.

I like how it sounds now and would like the same sound but deeper.
Thanks

 

I`m wondering about what mufflers to put on my 67 Mustang. I want something with a nice but no too loud rumble for highway cruising.

 

flowmaster super 44's are awesome, i got them for 110/ea. borla makes a nice sound too.

 

How loud are the 44`s, as in would they be fine on a trip?

 

always like the flowmaster 40 series
heres sound clips (theres a little button marked sound clip under pic of muffler)

Flowmaster, Inc.

 

I have heard some really nice borla exhaust too.
Flowmaster sounds pretty good from the few I have heard.

As for whether to replace your cats and h pipe, you know your gonna kick yourself in the *** if you dont do it!

 

in my '83, on the highway it turns about 3g rpm's @105 km/h... it's not bad at all. i was told that a higher compression engine will result in a louder sound, makes sense.

 

I had a Borla dual cat back on a Chevy half ton - I liked the sound but maybe too quiet for some. I currently have a magnaflow dual cat back on my truck and I like it. On a muscle car I think most of the guys I know have flowmaster. My friend with the 440 6 pack cuda has a TPI (I hope I got that right) and he has flowmaster mufflers on his 440 challenger. He prefers the flowmaster sound but I like the sound of his TPI system.

 

Yeah Flowmaster really brings out the deep throaty rumble on the mustangs but so many people dont like em cause everyone has em

 

3000 rpm at 105km/h? Your kidding right? That would be powerfull but terrible mileage! My 302 with the 5 speed (OD luckily) revs at 1600-1700.

 

My 65 has tri-y headers and cherry bomb exhaust which exits out in front of the rear tires. Has a nice sound when cruising, and really barks when you mash er right down.
I vote for magnaflow on your Cobra.

 

Sweet, a stock 289 4 bbl?

 

302 with cam, intake, holley 600 carb, 4spd.

 

i' m serious Prep. 14.4 mpg on the highway baby!!

 

That sucks! Time for an OD bud!

I have a couple of cherry bombs on my 89 and they are actually not that bad. I dont think thats the kinda sound that colin wants on his stang though.
