I had a 'turbo tube' installed and I replaced with a
stock (Mo$$) glasspack after about a month. The tube
sounded great but really resonated inside the car.
The stock (its made by Walker) muffler eliminates
interior resonance. It's got a somewhat odd note but
OK for me.
After switching to stock muffler I looked in the
turbo tube and saw a small (1/4 inch) hole where there
probably shouldn't have been one -- I could see
straight through the thing! Maybe that's why the tube
made my ears hurt after hard driving.
Personal note: after seeing my grandfather and father
both half-deaf from war and farm equipment I am very
protective of my ears. I'll give up a couple of hp if
