Good luck! had the alta on my old 53s and it was the best sounding in my eyes also, running a borla system now its as close but not the same

 

It is a beautifully designed product that I just WISH Alta would reproduce as I know there is an extreme high demand for their exhaust. I even messaged ALTA themselves and they unfortunately do not have any or any possibility to make anymore. What a shame.

 

How can that extremely sharp hairpin turn bend be good for exhausting gases as quickly and efficiently as possible? A straight exit pipe no bends no Y splits always best right? No tone here, asking tor a sincere technical explanation

 

yeah,
some people delete & relocate the battery so they can run a straight design which is probably ideal for maximum performance, but a daily driver is more prone to accept the exhaust packaging constraints & live with them best they can because ain't in fierce competition chasing ten/tenths time shave or whatever?

Actually, the Alta design is more fluid-gentle radius form than many others that i've seen,
like for example here's an old Webb Motorsport design which appears rather crude to my eyes:




but i really suck at mathematics & i ain't know about the pulses and backpressure and escape velocity either

this viddie is interesting,
"increasing exhaust back pressure via a restriction and the effect on power"

an experiment made by 4A-GE guy --- apparently alotta the old-heads in that community are vociferous about saying exhaust backpressure is needed & good

You Tube

anyway,
back to Alta . . .

. . . i wonder how many of the stealth version they sold?

there was so much variety in the aftermarket back then & lotsa people were buying&installing it,
but seems somewhat rare nowadays to come across the waybackwhen stuff
