Hi,

Last week i had my exhaust done in my country an x pipe with a good sound was hanmade .but it is not good for me.....i ad heard that boomtubes and flowmaster have the most dark rumble...but which 1 is the best?????

 

i have flomaster and i like them. So i am going to have to choose flomaster. Its just my opinion.

 

Flows sound better on the previous gen. mustangs. That being said, boomtube will sound better. Do you have cats? If so, keep them on with boomtubes. If not, no cats and boom tubes will be very loud and possibly annoying.

 

so boomtubes are really to loud after a while....als will install in the future an supercharger ...and maybe it is going to noise then??

 

Boomtube should be fine as long as you have cats on.

 

Boomtubes sound good also check out SLP Loudmouths I love mine... I will have to get rid of them eventually because I will be getting Long tube headers.

 

sorry it will sound very stupid....but what are cats???,,,,,......sorry...

 

Catalytic converters. Required for emissions in most places.

 

so what is the best rumble....flowmaster / boomtubes/ or SLP Loudmouths ???

 

Boomtubes. There's just no comparison.
