You are not looking at it very closely H.

 

Dave man I thought I was

 

While the welded strength plates are a good idea, we cannot see the inclusion length, but I do see tha the inclusion angle is different. Not good or bad, just different, and we do not have any dyno proof. I would also be concerned about getting something that large to here from Canada.

 

An X is not an X is not an X. Just because it looks similar does not mean it's the same. What Brendan was saying is that the chamber size at the junction looks very narrow. It does to me also. The size of that opening, the distance from the exhaust ports, the inlet angles and the outlet angles are critical to horsepower production. In their other photos it appears that they used bent pipe to create the chamber and added a spacer inbetween.

The reinforcing plates are a bit overkill in my opinion and do not allow clutch or flexplate work without removal.

I'm still more than willing to fund a dyno shootout...

 

It could gain you some low-end torque due to a little added backpressure!

 

I have an Ott )( .... I think it works well, I managed to get 299rwhp and 299rwtq out of Godzilla with it. Not sure what it was without it. Anyway that X looks to me very similar to an Ott, is ALL I was saying ... no more ... no less.

 

What are you trying to imply with this? Did you notice that the original poster never told us about the final outcome of his transaction? We really don't know all that much detail, and should not speculate.

However, you should remember that since 9/11, shipping to the US from abroad has become much slower. I feel that everytime I get a shipment from Germany, Canada, or else. Packages are sometimes held up for multiple days before they are released for delivery. None of my vendors can control that. It's just a fact of post-9/11 securitiy.

Similarly, Canadians might have reservations for getting an X-Pipe from the US with all the shipping cost and duties involved. I hear the Canadian authorities are ruthless when it comes to duty.

I expect most of these to be sold in Canada.

 

I think Roger's price is the best I've seen for a proven, excellent product. Roger!!

 

I am not trying to imply nothing just stating delays with the vendor that was discussed in the earlier thread. The delays was not only experienced by the person that started the thread!

 

Thank you H - you are an officer and a gentleman.
And its not true what Kim said about you :>)

 

oh sheeeet

 

You are funny H, we have had the same price for a couple of years now.

 

Take it easy, bro! As said in that tread, they had a huge ice storm at that time, all power and phone lines were down for weeks. Jager has been making high quality products for numerous years, except for the rim stickers (I personally didn’t like that invention), everything they invented/designed was good and of high quality.

 

Same there. The other 2 people did not mention the date that they placed their order so should we assume it was right after the storm? Other people has ordered from HK, Germany and got them in less than a week. I have got parts from UK in 5 business days.
Its a free country, let people make their own conclusions, whatever it may be.

 

Without actual measurements to go by, it's hard to really tell. It could be 2.5" size up to the end where it appears to have a smaller pipe size welded in to fit inside the rear exhaust section. Then again, it could be 2.25" with a smaller size welded to the end. The pipe size to fit inside the rear exhaust has to be quite small since the ID of 2.5" goes over the expanded end of the stock rear exhaust. I'm thinking that a size to fit inside the rear exhaust is too small for a slip fit into 2.5" pipe. Also with the smaller end, you couldn't easily use 2.5" rear exhaust piping. The center (venturi) part does look quite narrow. It does make a difference and possibly on some smaller motors might be ok. Generally, the smaller center will help the low end while larger will favor the high end. But then it's motor specific too. The center of the X where the pipes join is quite long. What that means is that the low pressure point in the center is removed by some inches from the pipe inlets on each side. How much extractive effect is lost there is a guess. Hard to know without testing. Dave Lomas experimented a lot with that aspect of X design. If you check the X-pipe pics on the web site, you can see that where the pipes first join at the front, the joint appears quite rounded with a large radius. The merge point is moved forward and blunted. Opposite to any merge collector I've seen. This will lower the velocity at the exit where each side comes together well before the gasses enter the pinched area. Lower velocity = higher pressure which is what you do not want at that point. The nice looking rounded center section looks like it will flow nicely and probably does. Maybe that's why they can have a smaller width there. One property of fluids flowing in a pipe is that they will tend to adhere to the wall of the pipe. Exhaust gasses entering one side will tend to adhere to the smooth pipe as it bends around the smooth curve and will continue right out the same side as the entry side. The velocity is lower near the wall and it pulls the gas stream right around the corner. Theory says this will happen and testing I've done shows it to happen. With a smooth center, about 75% of the flow will stay on the same side as the entry side. It's not even close to a 50/50 split. You do need the sharp break, or discontinuity, near the center to disturb the laminar flow and help equalize the flow of gasses into each outlet pipe. Other than that, yup pretty much the same. Like Dave, I'd like to see dyno comparisons. Still might be a good thing for the Canadian folks not having to deal with the border/duty thing. They can't call it an X-Pipe either. Maybe its ok in Canada.
