It is not a glasspack it's a muffler and Iran the exhaust for a couple of weeks without tips and wasn't very happy. Put the tips on and it gave it a much better (and a little louder) sound. The volume is comparable to a 40 series flowmaster, I went with Cherry Bomb just because I liked their phrase "Disturbing the peace since 1968."
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:
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
Magnaflow catback, dual exit. Haven't received it yet; but it was down to that or the JBA system. Wanted the Roush off-road system, but I like my neighbors. ....well, most of them anyway.
Installed my system over the weekend (catback, SIDO), along w/ a CAI. This system sounds great! Loud accelerating, but very quiet cruising. You only hear a light burble from the exhaust when in overdrive; but let's people know where you are when you're gettin' on it! Highly recommend this system to any anyone who is worried about drone at highway speeds; yet wants an agressive sounding system. No idea on whther or not it has improved mileage as some claim; but it is more responsive; and doesn't feel as though it's laboring to get out of it's own weight anymore.
