Re: Dyno Day
Well, it will be interesting to see what you get with the same system that I have. I guess it will come down to a test of the heads and your cams.
But, one of my "winter projects" will be to change the muffs to the 3" Dynas, and coupled with the new radius in my IHs, maybe I'll see 440 ish...not to put the screws to an old WOP friend of mine...at least not toooooo bad!  P.

Re: Dyno Day
Paul,
You'll need to do that on the same dyno in order to compare apples to apples. |

Re: Dyno Day
Got the SW Xpipe. I thought this was interesting and not expecting to see this:
  Is this a newer version? Trying to deal w resonance?? How does it affect flow? This "baffling" is in the aft part of the Xpipe. Its in the section behind the X where they are merged. Last edited by XfireZ51; 10-23-2011 at 10:31 PM. |

Re: Dyno Day
wow thats different . looks like the noise reduction cones that they put in header collectors to quiet open headers at the track . also kinda looks like someone welded a cheese grater in your pipes jk
 . sure could mess with your exhaust flow

Re: Dyno Day
Looks like an X pipe with a bad case of hemeroids!!
 I don't like it - at least not until there is some "with and without" data to at least show it is benign (which I doubt!). I guess we'd like to hear what SW has to say about it, as I'm sure you're going to give 'em a call. P.

Yeah I'll be calling them later today. I'll keep you posted on what they say. This is definitely not what they have pictured on their website. This isn't cheese grater stuff. It's bumps in a spiral pattern located in about a 10-12" section of the Xpipe behind the merge point and prior to the exit opening. |

Re: Dyno Day
Bumps reduce velocity loss against the wall of the pipe?
