First: I did a search, but I can't exactly find what the "y-pipe mod" is. Does is it the fabrication of a centered Y (in place of the offset Y)? or ______?

Second: Just a theoretical question for you all. Has anyone considered the fabrication of an X pipe which crossed back into a Y-pipe that goes to a single in & out muffler?

I figure than a Y pipe is similar to an H-pipe, so why not X it if possible?

The attached picture is pretty bad, but it gets my point across.

 

I guess you could do it but why? If you have a Y, it serves the same purpose as an X, bringing the pulses from each bank together. On a true dual system, an X lets each bank take advantage of the opposite side's exhaust piping.

Are you sure the fluid dynamic (and acoustical dynamic) properties of a Y-pipe and X-pipe are the same? (especially considering the unequal lenghths of the Y-pipe with respect to the 2 to 1 intersection)

So the Y pipe mod is essentially adding a mandrel bend to replace the crap bend of the stock?

Max- I really didn't understand your original description.

I can't find the tons of posts or pictures that describe it very well (hence the first line of my original post)

 

strike 3, I'm out

 

Here's the infamous jagged hole inside the factory Y-pipe. Some are far worse than others.

This is how it shapes up after the mod . I'm sure you can understand how the factory Y-pipe restricts the driver's side of the "Y" from flowing freely into the passenger's side.

Photos are " ala Jackal " I found them by using the search function.

Good luck Corpsie.

 

I DID search and the 20 or so threads I checked, the only thing valid was that the Y-pipe mod was mentioned, no pics, not links.

Thanks for the assistance everyone.

So any more guesses about my whack y-x-pipe thingy?
