[DeTomaso] 180 sound

[Göran Malmberg]

Chuck, agreed, it is of course easier making a crossover pipe as on the 
image
as compared to standard headers.
We have two issues here, sound and power. I was mostley discussing sound
as this was what the questioner asked for. I newer tried the 180 with 
cross-over,
so I really cant tell anyhing about it. There is one thing more I newer 
tried and
that is 180:s emerging in to a single big silencer, as 90:s ends up with a 
very big
collector.
