2. will anything happen if i delete one set?

3. which mods are recommended to have installed before installing a meth kit?

1 - Yes, one set is right before mufflers, and the others are attached to down pipes.

2 - I have deleted the rear ones, the sound has changed quite well but dont feel any power gains.. if you purhcase the dp without cats , you would see much better performance gains and throtier exhaust note, not raspy at all.

3 - I think before jumping into a meth system, you should get the air intake, dp, tune and new intercooler / the one that we have is very tiny comparing to aftermarket ones..
