I was changing my differental fluid today and noticed on both passenger and driver side mufflers had holes in them(rust related). Its the mufflers right before the tail pipes. I noticed about 3 other mufflers going down the belly of this car and was wondering if the rusted ones are needed? because i coudl easily weld up some stainless steel pipes to save soem cash.

 

the rear mufflers are called "Resonators"
personally i"d weld them
