My muffler has something stuck inside of it which is making a terrible noise while I drive down the road. I figured this would make it a great time to put a new exhaust system on it. It doesn't sound very good in its current form so I was thinking about putting a glass pack on it or making it a dual exhaust. I really want it to sound like a V8 so I'm really leaning on making it a dual exhaust. I was wondering if anyone could give me a layout that is relatively cheap with a good sound. Can anyone tell me what they did and how much it costs with possibly some pictures?

now you will never really get that V8 sound, from what im told its due to how the Inline 6 fires.

However, that being said, your car can sound quite Bad A** if you want it to. You can either upgrade your muffler, or... what I would do, is get a tuned header from clifford proformance with the port devider. This will collect three cylinders in one, three in the other. Coupled with two nice mufflers and you will have a nice sounding ride.

I will try to post some videos so u can hear what it sounds like

Here are the videos

The first one is really all you should need, and notice that both cars are using the dual header. :bigthumbsup

Let me know if there is anything else I can do to help

Having dealt with both, I would advise getting what you need from classicinlines.com .

Ranger1475, do you know how they connected the driver side exhaust in the first video?

You might think so, but the first time I saw a 200 with duals, it was a 66 with the 200 engine, stock 2" GT dual exhaust, and dual headers. It sounded like a 289 GT, but when it stopped, there were only four bolts in the aluminum wheels. I was impressed.

My 200ci is in bad need of an exhaust replacement as well, but wouldn't a dual exhaust reduce backpressure too much on an unmodified 6?

I'm not sure whether I need new headers or not, they are fairly corroded but not nearly as bad as the pipes, which have holes in them. Is there anything that I can bolt to stock headers that sound better than OEM?

Hey, looking back at the video, im thinking that there is no driver side exhaust, im actually thinking that it is not a dual header. Still a nice sounding ride but i would have went ahead and bought the dual header.

How would you have connected the drivers side exhaust, for the people who are considering this. Im not sure if there is a special piece you can buy or if you have to do a little custom work.

Go to you local exhaust shop. Have them install a single inlet/dual outlet muffler. That's what the PO installed on my 66 coupe. On mine the rest of the exhaust is stock size. He used a Camaro muffler.

Backpressure is bad. Ford engines do not need backpressure.

The 200 did not have headers. It had a horrifying 1-piece manifold, which forced the #1 and #6, and to a lesser extent #2 and #5 cylinder to push against the others to get out.

You want good sound, get dual headers and 2" stock GT exhaust with tailpipe resonators, and people will think you did a V8 conversion. The reduced backpressure will also improve, somewhat, performance and mileage.
