Do hard IC pipes actually cause a felt increase in power?? Or an increase at all for that matter

 

theoretically, mainly because with composite(plastic, rubber, whatever) there is always some flex from high boost pressure...since metal cant flex(or not nearly as much as plastics) the air has no choice but to enter your engine instead, now in the real world, hard pipes alone probably wont do anything for you that you'll notice

 

I kind of figured as much but I wanted to ask thanks for the info
