Re: 3.7 Mufflers, whose got'em?

The Magnaflow is probably quieter than the Gibson if I had to judge based on my personal experience with the Gibson and how quiet the magnaflow sounds on video.

Re: 3.7 Mufflers, whose got'em?

well depends on which magnaflow your looking to get.... stay away from the round exhausts if you want quiet... get the 5x11 oval

Theres nothing wrong with the round mufflers, but they have to be sized properly.

I talked with a Magnaflow rep a while back asking them about muffler dimensions and how they affect drone. The rep said that typically the width of the casing will play a important role in resonance and overall sound levels.

That being said, the 5x8x18 or 5x11x22 is probably a safe bet, but I just wanted to dispel the myth going around that round mufflers will automatically make your ears bleed.

Which the Gibson PN?

When I had my Magnaflow full catback exhaust with the 12"X22" oval muffler on before I can tell you it was "louder" than stock obviously when getting on the throttle, but cruising it was hardly noticable. From what you write I think you would be happy with a larger magnaflow straight thru muffler. It will not be loud so that your getting pulled over for it, if anything it gave the exhaust a nice tone to it taking off.

Even right now I have no muffler with the dual srt resinators and tailpipes and its not that loud compaired to my cousins Tundra V8 with just a Flowmaster muffler in it.

Re: 3.7 Mufflers, whose got'em?

So I had a 14" glasspack installed and the results were well worth the money. Highway and cruising drone is almost completely gone and the overall sound of the muffler was reduced by about 60%. Its still just a too tad loud for me when acclerating, but its much more tolerable. The weird thing is it seems like the Jeep is running better, maybe more back pressure?
