But much less fun.

Your new exhaust may just have an unfortunate resonance, its exits may be in just the wrong locations/directions, or there may be a number of other causes.

I have noticed something very similar in one of my other cars after essentially doing an "axle-back" exhaust line swap under very narrowly defined set of circumstances of rpm and load. In my case, it wasn't a dual exhaust system either before or after, no H or X pipe, not even a V8. IOW, heavy resonances can happen even if you don't have two pipes rumbling in sync (or just a really tiny bit out of sync) with each other.

Can you "drive around it" at all by upshifting or downshifting, or is it always there no matter what you try? Is your trunk either full now when it wasn't before or vice-versa (different resonances and damping possible) That's where I'd start.


bigray - If you're going to turn it around and try to help, please help by first doing no harm. Throwing out terms like Valsalva without identifying the potential risks involved in haphazardly trying out that technique is perhaps a bit . . . ill-advised. Never mind how I might know that Valsalva has a big potential 'downside'.

I was intentionally vague so people would <gasp> use Google and do their own research, which is probably what the OP should have done in the first place.

P.S. Your post was very irresponsible because it didn't point out the dangers of reading too close to a monitor or improper ergonomics that may lead to carpal tunnel syndrome. tsk tsk.

I thought that's what esl was doing . . . doing some research into whether his feeling of ear pressure was only an individual experience, and to perhaps establish possible causes of it.

If you're that good at establishing - from the get-go - the full scope of what starts out with a simple observation, try to have a little patience with the rest of us who are not as gifted.

Sounds (pun intended) to me like the OP isn't experiencing atmospheric pressure on his eardrum, but rather sound pressure. My suggestion would be to schedule an appointment with a Otolaryngologist (ear, nose, throat and neck specialist) to discover whether any permanent damage to his hearing has resulted from exposure to loud vehicle exhausts or music. I had Magnapacks on my car and they sounded nice and mellow and not much louder than stock with some drone at the usual RPM. After going FI, they got louder and the drone was unbearably loud. I switched back to the stock mufflers and all is good now.

We have been such fools. Instead of comforting a fellow stanger, we have perpetuated the stereotype of uncaring gear heads who believe antagonism is the best way to deal with ignorance, thus further emotionally isolating our auditorially challenged young friend.
I have learned my lesson. I am a changed man. Thank you ghost of Christmas past!

Its really difficult to pinpoint the cause. In my own personal experiece, my sinuses give me hell quite often and it just developed out of the blue and is now something I have to live with. This could be another example. There are days when I'm fine, and then days when certain noises, frequencies makes my ears hurt and give me a headache. Like yesterday, when I first posted, I had earbuds listening to music. I knew a sinus headache was coming because my ears started to hurt with the pressure of the buds in my ear and from the music.

Its really up to the OP on what he wants to do to help solve or alleviate the problem, but if it is going towards hearing loss, going back to stock exhaust may be a good idea.. and like other people mentioned, hearing loss develops overtime.. My ex-husband was like that.. he was gradually loosing his hearing due to working by loud machinery.

If you want to attack it from the hearing loss angle, be advised that permanent hearing damage happens when humans are exposed to sustained noise in excess of 90 decibels. I know some of our Mustangs are pretty loud, but the mufflers are pretty far back so I doubt you'd see those levels in the cabin.

Here's the real advice to the OP: don't tell the Navy about this.

Sarcasm is exactly what drives new members away or keeps them from asking questions to try and find out / correct things they / or previous owner might have installed on their cars.

I agree with Norm that he needs to provide more data such as does it change with upshifting / downshifting and speed changes.

Another member on here purchased the same exhaust I had and the drone was so bad for him personally that he ended up taking it off and putting something else on. each person is obviously different. The slight drone (to me) was unbearable to the other forum member.

haha, i love how things can go from one things to blown up with in two posts.

About the hearing, i hear fine. No hearing loss whats so ever, just slight earpressure that i thought may have been from ehxaust. It was making of an observation seeing if any one else had an issue. It may be a number of outside reasons behind it and the drone may just make it noticable.

I dont mind drone, my blazer had such a loud drone i just phased it out. My new set up isnt loud at all, i just feel the pressure at crusing speed. i may go back to chambered muffler.

Ive been on these type of forums long enough to know that there are always "that guy" one here. That comes with the territory i just accept it.
