I recently purchased a 2006 double cab with around 110k miles and it drones quite a bit. I'm comparing this to a 5.6 tundra I had with a maxflow (magnaflow knock off) and a 1/4 wave resonator I made. The tundra has way more drone than that setup and all the exhaust looks factory. The resonator looks like it is splitting from rust at one seam, but also doesn't seem to be leaking. The muffler is about the same but once again doesn't seem to be leaking at all. I have a small exhaust leak up by the cats somewhere but it is pretty small and almost unnoticeable.
I planned to do a muffler and dump the exhaust right around the axle before I drove the truck much, but the sound right now is loud enough. Do these factory mufflers or resonators wear out and get loud normally? In my head I'm guessing that could happen with rust and such. I drove one other tundra while I was looking that was about as loud. So the question is... Has anybody else noticed this before? The drone is actually pretty annoying when climbing hills and getting the whole ear popping elevation change thing going on.
PS I will probably cut the exhaust and turn it down right after the muffler to see if that helps, and if that doesn't help I'll just wait until I do a new muffler and 1/4 wave resonator. I was going to just do a stainless pipe right before the resonator and run a magnaflow knock off or something like that to keep the sound on the comfortable region. Climbing up and down canyons with drone hurts my head:grin2:
