Anyone have this on their Tc? For the ones that do is it worth it even on an auto? Also if its the same diameter as stock will it be safe to run with a system? I have a 1000watt amp and subs if it makes a difference.

 

same size as stock just lighter. will not affect a sound system. ive installed 2 of these and so far both people really loved them.

 

if u want an nst underdrive pulley pm me!!

 

watch out for these, i'd go with NST.......im still debating if i should get the AP
