4x4 w/ headers

[jmacintosh]

I have an 86 K10 4x4. I noticed the pipes off the collectors aren't the same. Driver's side goes straight back, Passenger side curves upward to get past the transfer case.

Are there any manufacturer's of exhaust parts that keep this in mind?

I you buy a kit to fit oyur truck, year, model, etc. the pipes should be bent similar to your current ones.
