Which slip on makes the most HP? Thanks for the help.

 

If you ae looking for a slop-on go with the HMF. The Yosh is a wuss.

 

My Z I just bought had a Yoshi slip on. It sounded crappy and I made them take it off. I can't tell the difference in power and it sounds much better with the stocker. Saved $400 too.

 

The HMF is a good value. Not the prettiest thing, but it does work well.

 

Go with the HMF slip on, that is what I have on mine and it made a really big difference. They are saying 4hp. bottom, 5hp. mid and 3hp. top.

How much louder is the HMF compared to stock?

 

Everybody asks about the noise on every pipe. Face it, if you want an aftermarket exhaust and more power you are going to increase your noise level. If you want quiet, stay with the stock otherwise you will be baffling your aftermarket until your power gains are diminished.

 

WP is right the only way to get real, noticable power is to accept the increase in noise but one way to look at is with all the extra power you are going to have you will be going that much faster from point A to point B that you will not notice that much extra noise[img]i/expressions/face-icon-small-wink.gif[/img]

Because they are noticeably louder than stock.
