Was thinking about running the intercooler pipes at 3" but spoke to a business within our industry who advised to only go 2.5" pipe.

Reason being you'll loose the compression.

I remember matty saying a minimum of 2.5" and with my limited knowledge would of thought 3" would be better????

I would of thought the entire set up would be compressed few seconds after start up and 3" would be better for more air flow in the intake surely?
