Engine/Transmission (1998.5 - 2002) exhaust system measurments

[RHerrmann]

Hey all, I was wondering if anyone in TDR land may have a diagram with lengths and angles of a 2001. 5 exhaust system ( less muffler ). My son is going to make me a 4" system in his metal fab. class at school. I thought maybe if someone had some specs. it might save him some time or mistakes. Also looking for turbo flange and short piece of down pipe to weld to the new one.

thanks for any help... .
