Down pipe

[obsdan]

Anyone ever fab up a 5" dp my buddy wants me to make him one but I'm not sure if it's worth. I know how much work is involved in the firewall. Do you think it will sound deeper/ be louder

Is the turbo is use THAT much bigger than stock?? Otherwise anything more than 4" is a tad bit of overkill. If you do pull off a 5" down pipe I'm sure you could get more than one order to fill.

Trimming/bending of the firewall seam would be required on top of the 5" dp fabrication.
