i have a 04 kfx 400 and now it has a stock exhaust and its gutted, it sounds horrible. i like hmf exhausts but i don't know to pick the performance or competition slip on. i want something really loud, something that has a deep sound when it's ideling but sounds like a dirt track car when riding, any help?

Wanting a new exhaust just because you want something really loud is juvenile IMO. Loud exhausts are one of the things that get riding areas closed because people living around them won't put up with the excessive noise.
