Duramax LML also has its own clearance issues which make a
true 5 inch dual system difficult, but not impossible.This
down pipe back kit features a 4 inch front pipe which then
converts into a 5 inch pipe that connects to our original
5 inch Y-Pipe. The tailpipes are designed to go up and over
the rear axle and exiting evenly on either side. The spare
tire will have to removed for installation.

Flo Pro has come accross a design issue that affects SOME of
the 2015 Duramax truck exhaust fitment. Previously released
products for the LML Duramax will fit the 2015 Duramax ONLY
if the Turbo Direct Pipe DOES NOT have a 3-bolt flange to connect
the catalytic converter.
issue is best described in the picture below:
on the left is the Flo Pro pipe. The image on the right is the
3-bolt flanged pipe that comes stock with SOME 2015 Duramax's.
We are unsure at this time if this is related to a build date,
or trim level.
