i can take better pics if you like.
edit;these tubes do provide more power.thats with out a doubt.only problem is,with my custom air filters,its making the car run a little lean.so its either ditch my custom filters and keep the z1 tubes or keep my custom filters and use the stock tubes.after testing,i choose to keep my custom filter setup and sell the z1 tubes.if they dont sell,then i'll just wait till i get ready to tune and put them back on.
