As per title. Makes bugger all odds what size the tailpipe is, surely?

Silencer size etc is what dictates sound isnt it, the tailpipe is just a cosmetic thing?

Just its always been one of them internet myths you hear, that a mongoose with a 3in tailpipe sounds different to one with a 4in one etc etc even though it has the same backbox barring the welded on tailpipe, but ive never checked.

So, its it bollocks, or what?

 

4" tailpiped goose's do sound louder than 3" imho

 

I've had 3" and 4" mongooses and scorpions on my RST's and the 4" pipes have been considerably louder each time...

 

ive got a 4inch mongoose, and heeman has a 3inch mongoose and is pushing about 70bhp more, but mine is still louder by a long shot

 

Interesting, i didnt believe it, until now...

 

I guess the only definative way would be to use one car and then swop the exhaust systems over and measure the sound

 

Makes a massive difference Steve

 

yep, tis true.

my powerflow had a 5" slash cunt pipe, was too fucking loud and hurt your ears.

my mates had a 3.5" slash and rest of the system looked the same, but his was much quieter

 

its about how the sounds projects from that tail

 

No Shit!!!!!!!!!!!

 

my 4inch sounds louder than my bruv in laws 3inch goose, and my old 5inch slash cut on my RST was too damm loud

 

of course the tailpipe size makes a difference - just look at musical instruments in different sizes

 

so if by chance a 4" was too loud for track days ,could you make a sleeve to slide in and make it 3"

 

 

i never believed it either untill 1 day at college when i was doing machineing i rolled a bit of steel to about 7"'s wide and put it over my mates exhaust. it was hanging about a foot out the back of his car and it made quite a difference to how it sounded. that was even with a load escaping where the 7" was quite a tight fit over his existing tail pipe

 

why do you think my exhuast points down??

alot to do with noise other than silencers

 

never would have believed it you learn something every day
