I have a question. Is the factory exhaust system on the 3.7 stainless steel? Mine seems to have gotten louder but seems to be a resonance only. Upon acceleration it's not noisy. Anyone have any problems?
my muffler on my wk when I had was all swollen and coming apart on the inside... it was probably exactly like yours, not excessively loud, sounds stock really when you dont have another one next to it. I also had 205k miles on it.
Thank you! The dealer checked the exhaust system the other day when it went in for service. They said that it was tight with no leaks so that's my only concern. I have around 67k on the jeep now and it runs great.
I just hit 60k with my 3.7 and my exhaust looks like it was submerged under salt water for the past 5 years. I cant believe how much rust it has!! Even the muffler is starting to show signs that exhaust is leaking at one of the seams.
I am probably just going to replace it in the spring with a Magnaflow SS CB and be done with it.
