I'd like to see a CFM flow test before I used that piece.

Your halfway there,now have Al order 2 mufflers for you,don't half a$$ it,let her breath.
It's like having a marathon runner breath thru a coffee stir.

Pete,

You really think the magnaflow mufflers would be a restriction? Have you seen them in person? They are nothing more than short 3" smooth perforated tubes. No baffles and no reduction in diameter.

I'm running a 3" system with a magnaflow x & mufs. It's loud and has some resonance with the top on, but sounds awesome with the top off.

Says on the SW website its ribbed for pleasure!

All,

I just got off the phone with SW. The piece I got is their "resonated Xpipe". I was told by Paul at SW they don't build them any other way but they would for an extra $100. Needless to say, I'm confused. Paul W. I believe has a pic of his SW Xpipe and it was clear thru. The "baffling" is there to hold down the resonance. I agree w Lee that they are there to break up any standing waves which would actually impede flow. Maybe our resident Fluid Dynamics guy PW would care to chime in. The spiralling is similar to a rifle barrel leading me to believe it straightens out the gas flow. The twisting probably helps to "compact" the stream.
Discuss amongst yourselves.

JRT,

I agree. Don't see the impedence on the MFlow muffs. At the least, its negligible.

Not sure but i know Dom's MF mufflers go from 3" to 2 1/2 inlets.

Dom, you went from banana to grapes in the tailpipe.
I gather you like fruits.

would be interesting to see back to back dyno runs and see which dynos higher, even flow rates would be great to see. I wonder if the little bumps hurt anything, they way their designed looks like it may help suck the gases out a little better.

hmm, well I may not be running the exact mufflers that come in the magnaflow kit, since my system was built ala carte

Seems to me SW is getting too big for their own good.
I remember the days when they were begging for business.
Now the @sshole wants another $100 tell him to go f@ck himself just get a refund and for that price make your own or send it to China have them copy it,it would cost $50 then SW will go back to the days they were begging for business.

Dom, get a refund i have found another source/way,cheaper.

Now how is this possible $200 you get all this with cutouts,covers,flanges etc,

SW you pay almost double and get less.

At these prices i would go with mild steel X-pipe and ceramic coat.

Guess who SW got the measurements to start making X-pipes for our Z's.

Get a Magna flow Tru-x 3 inch, have it on the 92.....for less than the SW you can get the dmn thing installed at Twisted Pipes
