Here's one for you exhaust experts -
I recently had my muffler and exhaust replaced on my '91 Ex. Each time previously that I had to replace it, the exhaust pipe rusted away from the resonator (juice can-looking thingy). Well, this time, the shop decided to install an exhaust pipe without a resonator, explaining that mufflers are much better than they were 20 years ago, so I shouldn't need a resonator. Made sense to me.
But in driving for the past week, I noticed that I'm going through gasoline a lot faster than before. My mpg looks like it's dropped off a few.
Question - does the presence of a resonator, or the absence of one, effect my gas mileage? Is there a deal here having to do with more or less backpressure?
I just don't know, so I'm looking for input.
Thanks in advance.
