3.5" Mufflex Installed
Here are a couple of pictures of my 3.5" Mufflex system with the Magnaflow muffler. This is with the single tail pipe tucked up. It is not that noticeable to the causual observer. Had to stoop somewhat to get most of the tailpipe.

Not loud at all. Probably close to what the factory is until you nail it. I can drive down the street with the windows down and have a normal conversation without raising my voice.
I do not recommend this muffler to someone who wants a loud exhaust. Plenty of ground clearance. Again probably close to the factory ground clearance.
Dyno Don did the installation and had no problems with it. He does custom exhaust systems anyways so it was a piece of cake for him.

care to say how much the whole setup (minus instal) set you back? while i like how my bassani sounds, its a 3 inch setup and ill need a 4 inch setup sometime in the near future to go along with a 4 inch downpipe. plus i dont like tips sticking out nor a very loud exhaust. so this may be right up my ally. thanks for posting this.

I bought the 3.5" Mufflex cat back system in a group sale. It was around $400 with the Spintech muffler. After I received the Mufflex I learned that Magnaflow was going to make a 3.5" muffler that looked exactly like what I wanted. So I placed and order for it through Summit. Cost was around $115. Now you can get the Mufflex catback with the Magnaflow muffler as Mufflex is also a Magnaflow dealer.
