I have to agree, Titanium mufflers and exhausts are not expensive. I also have a hard time believing that they make one for 65 bucks......the HKS 4" Ti exhaust on my supra was over 1g and only the muffler is titanium.......granted you pay more for the hks name and the fact the piping is 4".......but I'd stay away from any muffler that cheap, you get what you pay for.
