you can find an aftermarket pipe for 1zzfe in Lahore but have to do some working as its not very commonly available, meanwhile u can use the one made for 1nzfe, it has slightly different bend from one side but still u can fit it and should be better than ur existing one as having to joints leaks etc...
use genuine clips with pipe, dont replace then with jubilee clips.
cost of pipe is not more than 500 for aftermarket one, its been in market for over 15 years now so many qualities available suiting ur requirements.
