I plan on getting a GT Dual takeoff muffler, just wondered if the sound will change a little bit or will I have to go with a CAI as well? (Sorry, NOOB-question)

 

I definitely think you'll hear a change. The GT mufflers provide a deeper tone than the stock muffler. I can't say from experience or anything because I have a Magnaflow, but I'm pretty certain you will get a noticeable difference.

However, gettinga CAI will certainly help. Of course, getting a CAI with the S197 usually means getting a tuner with it. So if you want to go that route, plan on spending at least $600 for a CAI and tuner. From everything I've read, it is certainly worth the money and more power is always welcome!

 

Well from inside the car, I CANNOT tell a difference. From outside the car, it "almost" sounds like a V8... Before pics>

I have the same setup as Willie. I'm very pleased with the sound. It's deep and mellow - night and day versus the stock muffler. In my opinion, the GT mufflers sound as good or better than any of the aftermarket mufflers.

 

Will I need the OEM H-Pipe, or will something like that do the trick?

 

Think about the dynamics of the gas flow on a setup like this. Personally, I wouldn't even consider such a configuration but hey, it would be a cheap way to do it.....

Buy the GT OEM Midpipe and OEM hangers. A good muffler shop will be able to fabricate the H for you and tie it it all together. You don't need the GT H pipe.

 

Looks great! I bought a set of GT-Take offs mufflers and plan to convert my stang to true duals once my pipes come in.
When I bought the mufflers I covered the tips and painted them silver with engine paint. Some say why bother, me, I just wanted it to look good all around.
Here's a picture of my mufflers after I painted them....the tips are still covered;
