Wow...that is all I can say about the Polished SS Magnaflow 14326 I just installed on my truck two weeks ago. Have only a 4.6 that sounds like a beast without any drone. Not way to loud, but definitely lets people know you are proud! Specs on the muffler are as follows:
Material: 100% Stainless Steel - Mirror Finish
Body Shape: 4in.x9in. Oval
Inlet/Outlet Size: 2.5in./2.5in.
Body Length: 14in.
Overall Length: 20in.
Core Size: 2.5in.
I simply installed an extension into the factory clamp (the one furthest from the engine before the stock muffler) so that i could mount the Magnaflow near the end of the heat shield allowing for a nice professional looking hanger mount. I topped it off stealth style with a short 6 inch piece between the outlet of the muffler and a polished SS rolled edge tip. The polished muffler and tip show up nicely from the rear passenger wheelwell and when sitting in a car behind me. I love the sound because of the throaty sound without the drone inside and the cackling when you let off the gas. The way that I mounted the muffler eliminates all the bends in the exhaust system after the y-pipe following the factory resonators.
I hope to take some pictures soon as well as record the in-cab, drive by, and outside idling performance
