PROFLOW EXHAUST QUESTION 2.7 2tr

I was doing exhaust research on LC engineering and the website stated some cutting might be required on some trucks. However, they didn't specify which models would require cutting. Is cutting required to install the Proflow exhaust on a single cab 5 lug '10 tacoma? Has anyone here installed this for the 4 banger?

 

This one? https://www.lceperformance.com/Pro-Flow-Exhaust-System-2TR-Tacoma-2005-2017-p/1042025.htm

Looks like it just says that the front pipe length can be trimmed depending on cab length (ie probably shipped as a Double cab unit, and can be cut down for a single cab).
