I have a 1987 Jaguar xjsc trying to locate the mufflers..In the middle of the car there's 2 that looks like mufflers.. then there's 2 at the end just before the tail pipe also looks like 2 muffles.. which are the muffler.. or is one set resonator's.. hate to pull off the wrong one's..thank you for your time

 

I may stand corrected but I believe the rear two are resonators.

 

All resonators are mufflers but not all mufflers are resonators. They all muffle sound. The job of the resonator is to tune-out particular sounds that, for whatever reason, the main mufflers can't.

But, anyhow, the rear mufflers on your XJS (and many other cars) can be...and typically are.....referred to as resonators. So if someone tells you to remove the resonators you can bet money that they're referring to the round, straight-thru units at the rear of the car.

Thanks I thought that but wanted another opinion
