3" cross-over pipe

[k3500man]

is a 3" crossover pipe a good idea or sheer maddness and a waste of time/effort?

I have a 6.5 burben and I have one on mine. The turbo spools faster but if your looking for big ganes then add a turbo back exhuast too....

3" for 4 cyl. ? OVERKILL !

You got one ? Nice, but for what ? The crossoverpipe only got 4 cyl. to the turbo, so in my opinion, the stock diameter is absolutly okay.
If you have to change the stock pipe, cauz it is crunched or got a rusted hole in, you could change to the 2,5" mandrel bent version from SS Diesel, or any other vendor like warpspeedperformance, heartthrob, etc. who sells it.

A mendrel bent, free flowing 4" turbo back (3" Downpipe and a 4" system) is much more important than the crossover pipe.
