Will the Alston SFCs fit while using the stock exhaust routing?

Also, where is the cheapest place to buy them? I checked AlstonRacing and TDS and both are like $190ish. Is there anywhere cheaper? They just seem extremely high in price considering the Spohn and UMI/BMR style (though different), uses more material.

yes, they are supposed to.

these are the same ones, no pic, but it was linked through another post here on the same topic.

cheapest anybody has found

price reflects every aspect of the connector, the alstons have some complex bending and saddle mounts for the subframes, so they probably take a little longer to make.
