Alright, have another odd one for the forum...
I just got Lazarus (2005 LX) back from the alignment shop - so it's the first time I've actually really been able to drive it ever! Super excited about that. Mechanically drives like a dream & all is well on that front.
However, above about 40 miles per hour I get a super low frequency 'drone' in the cabin. You can barely hear it, but holy crap does it make my ears hurt - feels like it's building pressure on my eardrums. If I'm going down a decent hill (i.e, no load on the engine) it goes away even at speed. I can rev the engine at a stop and it doesn't do it - seems like it has to be under load.
I do have Doug Thorley headers on it, but I've near heard of anyone having this issue with them.
Opening the rear quarter windows helps a little, but not much.
Has anyone had an exhaust leak somewhere cause something like this? That's my best guess - some sort of odd leak that's causing low freq pressure spikes. Open to other ideas though - it's a weird problem!
