Title: Re: after market exhaust Post by: bigsteve on June 08, 2005, 12:27:45 AM Check out first which one is going to give you the most gain in HP, low end ,mid range, and how high the db levels are. I think HMF runs alittle high in db levels. I could be wrong so just check for yourself.
Title: Re: after market exhaust Post by: gtnwood on June 08, 2005, 06:58:34 AM Thanx 4 yur input wheelie_boy and bigsteve. Im not worried about db so much as that can be adjusted I just want the most HP. Big Gun says they make 3.5 - 5 hp, HMF does not give HP gain.
Title: Re: after market exhaust Post by: Truegrit on June 10, 2005, 08:16:00 PM HMF Utilities will give you the most HP. Average 5-6 HP YOu can push it up to 8-9 if you add a complete jet kit and high flow filter. The pipe produces around 106dbs at WOT, you can et the quiet core for them for $20 it will not noticably cut power but it will cut the noise down to 98dbs.
I love the sound and the power it added. It was well worth the money. Title: Re: after market exhaust Post by: gtnwood on June 11, 2005, 07:57:42 AM Thanx Truegrit, I'm gonna do just that. By the way some one told me if I use a K&N I cant use a closed air box, which would cancel all the canal water crossings I do. Is that true. Thanx again, gtnwood

Thanx again, gtnwood WHAT?, I would stop talking with the person who told you that. They probably can't even tie their own shoes. That is simply ridiculas.

By the way some one told me if I use a K&N I cant use a closed air box, which would cancel all the canal water crossings I do. Is that true. Thanx again, gtnwood I've got a wolverine and use a K&N filter on it. It's a closed air box. Only thing I'm looking for is the cover to help keep it clean. Haven't found one yet. Since we're on the subject of pipes. Thanks for the info. I'm looking into a new pipe for mine. Need low end increase in power just don't want any more noise than mine already produces. Where can I find the db level of my current pipe so I can compare it to a new one? Title: Re: after market exhaust Post by: Yamaha72 on June 27, 2005, 10:38:02 PM I'd say the Big Gun
Title: Re: after market exhaust Post by: Truegrit on June 29, 2005, 09:47:55 AM HMF Ecosystem wil give you a couple (2-3) HP and was no louder than stock on my bike. I think it was around 89-90 dbs at WOT.
Title: Re: after market exhaust Post by: KXKID on June 29, 2005, 10:20:49 AM I'd say the Big Gun me too ;DTitle: Re: after market exhaust Post by: Robert yfz on June 30, 2005, 09:33:00 PM I would get the big gun thats what i have on mine
Title: Re: after market exhaust Post by: jon457 on July 10, 2005, 10:54:20 PM hey i have asked the same question to dealers they all tell me the hmf but then again that is something they just tell me i could be wrong
Title: Re: after market exhaust Post by: Exmx54 on July 12, 2005, 02:58:29 AM I'd go with the HMF ecosystem for a utility. HMF's customer service is awsome, prices are more then reasonable, and I'm sure the power will be there, they make a dam nice pipe.
