Hmmm. I didn't know this. I got more top speed when I had it ported but not much. I had GPS my friends stock machine on pavement and got 68 mph. Then when he put his RcR top end pipe which is supposed to be around the same as HPD's stock pipe and only got around 70. After I had mine ported by Rick I got a top speed of around 74. I don't know why I would have different findings than you? I KNOW you know what you're talking about but it just seems strange to me. The acceleration from a stock to HPD pipe is quite a bit better too so it would stand to reason to me that it would reach top speed faster as well Mine isn't clutched the way HPD reccomends but I like the way I have it.. Please educate me.[img]i/expressions/face-icon-small-wink.gif[/img]

 

I can't find anything on the HPD trail pipe, but then again I usually have a hard time finding stuff on the internet. Anyone got the web site address? Thanx

 

I emailed you back and sent you a link. Here's another one. It's at the bottom of the page.

Thanks a ton Shawn you've been a real help
I'm seein' some pipes on "http://www.aaenperformance.com/Power400.asp"
Looks like the top end pipe is pretty compareble...does anyone have any experience with this one?
Not that I'm doubting you guys...just lookin at everything before I buy something

 

if your gonna get a pipe then you better invest in a wiseco.

 

it's 5 o'clock somewhere!!
Usually...but around here we say "it's noon somewhere"

 

Where's "around here"?

 

guess I'm not familiar with Wiseco...Do they just do pistons?

 

Aaen have really good products. But in my opinion the HPD make more horsepower. That's just my opinion now people.
