It is louder than any bolt on cat back system for the Titan. I think it is the best exhaust system I have ever had, performance and tone wise. Check out Aeroexhaust.com for any details about their products.
fisrt, your titan looks bigger than your house...second the exhaust sounds sick. the "muffler" is so small it looks crazy, but sounds nice. and thats just reving it up, im sure it sounds way better under a load:cheers:
