Yeah, unanswered questions....

My gauge detects air velocity in feet per minute @ 70F, with graphs for converting to other temperatures from 40F to 1,400F in 200F increments at anything over 100F. Unfortunatly I would need to drill holes in the exhaust to take my readings, which I'm not overly thrilled to do.

I'll have to really think about this valve idea.

I can also manage backpressure in the rear muffler itself without a valve, but it wouldn't be as instantaneous.

 

Found these two sound clips of the Kreissieg exhaust. Starts out with the valve open, then switches over to the quiet setting in the first video.

I'm pretty sure it's a butterfly valve. But I'm guessing they route it through chambers in the muffler. If you go to their web site you can kind of figure out how they're doing it.

 

Recently introduced.... Damn...

If I end up adding a valve it will be just ahead of the rear mufflers. I want to be able to replace the packing. And it would be much easier if the valve wasn't inside my baffles.

Que?:confused5:

Got an appointment for 4/2. I think it's a bad cell.

 

Sorry, no.....
I've been focused elsewhere. Just too many paying projects at work.

Re-modeling of one of my rental units is about 99% done. I hope to get back on my personal projects soon, like maybe this coming weekend.

In the mean time feel free to tell us about your pipes..... I was kind of curious how you made your's sound like a 747 doing a fly by......

 

Well, I was able to spend a few hours down at the shop working on a couple of projects.

I repaired a MOM member's JCW strut bar.

Then I did a little work on my rear exhaust muffler. The housing is complete, however I still need to make the hanger bracket that will attach to the stock rubber isolation supports. I cut the two perforated tubes that will create the separation space for the ceramic insulation. The two discs will be a part of the rear hats that will cap off the rear of the muffler (I will punch a hole in each disc so the exhaust gasses can exit both cylinders)... That's it for today.

 

I've got sooooo many half started, half finished MINI projects going (that's the same thing, isn't it????)...... I guess I hope so. I've been finding more time to be down at the shop on the weekends with my wife being away at horse shows. The exhaust requires a lot of "under car" measuring of the existing exhaust. Without a lift, I've been dragging my feet a little on that part of the project. This weekend I'm going to see if I can use my forklift to raise the MINI from the side, since I have 8 foot forks. Will see where my jack pads line up with the forks.....:arf:
