Magnaflow mufflers are reversible so this is possible using them.

That's good to know. Would there be any advantage to doin' this, like there is on a Harley?

Flowmaster has "scavenger" Y collectors which are suppose to make the Y flow better.

Just to make sure we're on the same page: A V engine has 2 banks of exhaust ports; as such, it will have 2 headers coming off the engine, one on either side. The headers bring the exhaust gases from the cylinder heads, converge them to one pipe at the end of the header, then lead the exhaust gases to a Y that converges the exhaust from both headers into a single pipe.

So, you could theoretically get a DI/SO muffler, cut out the Y, and route extensions to the pipes from each header into either side of the muffler. However, I don't know that there would be any benefit from doing this, because all you're doing is eliminating the Y and a section of pipe, which may or may not improve exhaust flow. I say this because as long as the Y and that section of single pipe is sized appropriately for the amount of exhaust the engine produces, you're not adding any additional exhaust capacity vs. if you left the Y in place and replaced the stock muffler with a better flowing aftermarket muffler. If the Y is not a good design and/or the pipe is too small, you would be improving the exhaust flow.

Full dual exhaust would involve headers, typically a X-pipe, H-pipe, or Prochamber (to mesh the exhaust flow from each side, but still provide full capacity; I don't have an in depth knowledge of this), then 2 pipes w/ 1 muffler each running the full length of the vehicle. I'm no expert, but in the case of V engines, I believe this configuration usually produces the most horsepower on a properly set up and tuned engine.

It wont change much. Because its actually 8 to 2 to 1. Thats the theory behing the tri-y headers. Helps scavenginging,reduces pulsing etc.

That stinks... now I've gotta save up 850 for a set of those thorley headers... those look pretty sick.

Good info. Thanks.

I guess I just figured that the muffler would do a better job with the gasses than the Y pipe.

I was thinkin' the same thing. lol

Cant say for certain,but thinking back to racing days.....
On mustangs you have true duals,h pipes,and x pipes. Each has benefits,as well as drawbacks.
In dirt track,like a late model,you have crossover headers.
Exhaust is some tricky **** if you don't know what youre doing.

These are crossover headers.
