Post Stromung midpipe...louder or not, faster or not?

I performed a search, but couldn't discern a definitive answer. Perhaps recent activity has made things clearer, but at present, here's the deal, judging from posts:

It's louder with the midpipe.
It's quieter with the midpipe.
It's quicker with the midpipe.
You lose some low end with the midpipe.

I suppose the most definitive answer is "Try it for yourself, dummy," but I was hoping not to have to buy one to figure it out.

Anyone?

I think it is louder with the mid-pipe, ans you do lose some low end. But you get some more above 4000rpm. At least thats what the but dyno tells me. I think it is a great set up, sounds good, and if you go for it get it in stainless. It will last forever.

louder with the midpipe, not much, but it resonates with a deeper, more forceful tone.

rev's quicker with the midpipe (not much though)

didn't notice much power difference.

Thanks, gang. Given the low end issue, sounds like I should stick with the stock mid pipe.

I ran my car stock then put on a stromung dual tip(without midpipe). I also have an air/fuel meter. With the stromung dual tip the noise was INSIDE the "cabin" (where you sit, droneing in your ears). The air/fuel meter has a bargraph on it and with the stromung dual tip it read "one" bar leaner than without the stromung dual tip. It was still one bar on the rich side. Power came on stronger at 4000 RPMS.

I then finally bought a stromung midpipe. installed it with the stromung dual tip. The noise is now comming out the back of the car, not droneing in your ears, much more tolerable. The air/fuel meter is now running one bar less (14.7:1) perfect! The car pulls harder up till 4000 and from there its the same as before. The power curve is now very linear, much better.

The bottom line is "Yes its worth it, If I had to do it again I would buy the same thing!"

I also have an ISR K/N air intake

Its on a 2000 RS 2door

The air/fuel meter has 10 bars on its graph, 5 lite is 14.7:1 Its made by K/N.

Well thanks Andy, now I'm TOTALLY confused. The noise migration was something that I hadn't considered. Has anyone else's experience paralleled Andy's. That alone might make the midpipe worth it, since around 85-90 mph, I get some drone in the cabin.

Not that I would advocate anyone's driving that fast, your mileage may vary, this is not a toy, close cover before striking, etc...

I suppose the best solution is to give it a try and see what happens. It's only $125, after all.

I'll post on Sunday and let you know. I have the dual tip installed right now and I'm installing the midpipe on Sunday.

Has anyone tried the custom SS midpipe from Mike Shields at www.spdusa.com ? Was thinking of getting that and would appreciate feedback on the diferences between that midpipe and the Stromung SS.

I just installed the mid-pipe after about a week or so of having the dual SS tip only. I found that the mid-pipe definitely quieted and mellowed the exhaust down. Before, without the mid-pipe, there was definitely the droning mid cabin and the exhaust growl was much more pronounced. It was louder while blipping the throttle. Very drony from about 2500-3500rpm mid-throttle, quieter till about 4500 and then the scream at higher rpm's. After the install, the drone was gone at the lower rpm's and the volume basically shifted rearward. It seems to be "loud" only when you really want it to be (WOT). Still noticeable volume but I think its much easier to live with.

One other thing is that it seems to "pop and gurgle" more on deceleration as well as in between shifts with them mid-pipe on.

As for power gains, don't know if its just the "volume placebo". Seems to rev more freely and pull a bit harder.

I'm still waiting for my ECU to finally figure out what it's doing I didn't reset it after installing the SS Dual Tip and SS midpipe because I wanted to save on gas money (yes, that money was THAT important to me at the time), and I know that the ECU will learn without being reset, but it can take a month :-x

Arnie.... Pop and gurgle?? Are you sure you dont have an exaust leak? That will cause all kinds of noise depending upon how much it leaks. IT can cause popping/backfires upon decelaration also

It's our unequal length headers that make the pop. They may be what causes the gurgle too... in any case, they all do it.
