I know I've made a few threads on HMF pipes for a 250ex, but I was wondering about something. If any of you 250ex riders have an HMF pipe on your quad did you gain alot of HP with it on and how much faster do you excellerate. I wish I could hear a sound clip of a 250ex with an HMF pipe on it. If you know of a sound clip where you could listen to the sound of the pipe on a 250ex give me the link.

I have to know a few last things about the two pipes that were brought up. If somebody can please help me out on these questions I will appriciate it very much!:macho

I heard the sparks exhaust was very similar to the FMF which i want to know if thats true or not, because i'm not fond of FMF pipes. And which is better quality HMF or sparks? Which gives more overall power and I only want answers for a 250ex.

Also what are the decibel ratings without quiet cores on the 2 pipes HMF and sparks? I searched and searched but had no luck.

I know the sparks is 95 db's for the 250ex, but what about the HMF?
