If it's a cat back system, you don't need an adapter.

MIL eliminators are needed if you run non-legal headers.

Sound is subjective. What sounds good to one guy won't to some other guy.

You can go to MustangExhaust.com and check out some clips.

Mufflers determine sound more than any other component. Anyone who says they can hear a BIG difference between an h-x-or y-pipe has been breathing too many exhaust fumes.

I put True dual exhaust on my 1995 3.8
I used Cat Back take offs from a 2004 Mach1. I went to the local Ford dealer and purchased the Driver side and Passenger side Hangers. Then took it to a local muffler shop to install.

2004 Mach1 Take Offs $150

Ford OEM Hangers $50

Install Charge $100

Total $300



A Ford 3.8 V6 is an even fire engine and does not require a H or X pipe. The H or X pipe is more effective in V8 applications where it helps reduces backpressure when exhaust cycles occur consecutively on the same bank.

actually, it helps evacuate the cylinder that fires before it.

The 6 benefits from the h-x-y-pipe in the 3-4 & 6-1 firing. It doesn't help as much, but it does help, & can provide 3-5 hp.

With a 1-4-2-5-3-6 firing order on a 3.8L Ford V6, the exhaust events alternate between banks and never occur consecutively on the same bank.
There is little or no reason to use a H or X pipe.

There are dyno sheets to prove it in the archives

5 hp isn't much, but it's still 3%

I was looking for dual exhaust for my stang....It seems rediculous for Ford to combine the exhaust into one! I don't think it would've hurt at all to keep the V6 dual! What do you all think of having one muffler in the middle, with two out ports, making dual tips?

I believe the best bang for the buck, is to find a V8 person in the local Mustang club that has upgraded his/her exhaust and buy his/her Cat Back Take Offs. Take the Cat Backs to a muffler shop and have them installed. I had the muffler shop cut my Y pipe just past the O2 sensors and install pipes with factory type flanges which connected to the Cat Backs. If a H pipe is a must have Pacesetter makes what you need.

True dual exhaust will help support any engine mods you make in the future far better than a single muffler with 2 tail pipes.

You guys need to check out this site http://www.completeexhaust.com/index.php they have everything you might need and if you call you will get awesome prices.Just purchased a Magnaflow Magnapack CB for $345 shipped.They have the pipes for dual conversions too for the V6's.Just trying to help.

zero sum gain.

It's got a single exhaust to keep costs down, and to keep insurance underwriters happy.
