[2 The X]

This past weekend an exhaust shop installed a "Wide Open" Magnaflow muffler on my X. All the piping is OEM. . .this was a simple replacement of the OEM can.

Results: Exterior tone is very deep and aggressive. However the interior resonance at 2000RPM - 3000RPM is excessively loud. I was wondering if anyone who had done a custom exhaust had any feedback on what aftermarket muffler offered "low level" interior resonance.

I was originally interested in a Flowmaster 50 series for SUVS that is a 3 chamber muffler advertised as an interally quiet muffler. The muffler shop claimed that the Magnaflow was actually quieter but I noticed that it didn't appear to have any chambers. I might be mistaken but aren't chambers w/in a muffler supposed to cancel out sound waves thus limiting interior/exterior "sound".

Any feedback on a "quieter interior" muffler would be appreciated.

with the muffler wide open, do you notice a loss of power at all?

I had a Flowmaster 40 series on with custom piping. I was a very deep aggressive sound. I didn't think it was too terribly loud inside, but it was enough to wake up my roommates when I left for work in the morning

Back when I had my '02 Ranger Edge 4x4 (4.0 V6), I installed a Flowmaster Delta 50 series muffler along with 2.5" pipe from the cat back.

It sounded great, however, after a while the interior droan gave me a headache. I regretted making the exhaust "upgrade".

Stay away from the Flowmaster. Most people call them Dronemaster. I Had the catback system from Flowmaster on my camaro when I first got it a long time ago. After a couple of years, i hated it. I now have Magnaflow. Magnaflow is one of the quietest mufflers when it comes to drone. All performance mufflers will have some sort of drone arond 2000 rpm's or so when cruising on the highway.

Do the Gibsons drone?

With the Magnaflow "wide open" technology I have noticed a small loss in my low end however when the RPMs get up the truck definitely moves. If you can deal w/ the interior droan/howl, Magnaflow is a definite winner.

I did the same can switch out with an Ultraflow muffler from
Dynomax. Then the rear tail tip section of piping was cut out to
make a side exit exhaust. I think the straight out the back under
the bumper exhaust tip doesn't look right- like the Gibson.
It looks out of place IMO.

I had the same interior resonance at ~2000 rpm the first month.
But over a few months since the install, the drone has
lessened somewhat and is barely noticeable most of the time.

thats called going deaf
i had a mustang and a lightning before my X, so i now am against having exhaust on my DD, it gets annoying, my lightning i couldn't hear myself think... it was fun on like 10 maybe 15 minute drives, after that i wanted earplugs.

-edit- btw, from what i understand magnaflow's regular mufflers are one of if not the least droning mufflers around, although i would assume sense you got the "wide open" one, that would be more like the magnapack, that is one of the loudest mufflers you can get

Hmm, I hope you don't wheel that side exhaust X.

My tailpipe is all smashed up and it's tucked up behind the bumper. I can only imagine what it would look like if it was stickingo out the side.

Depends which Dynomax you get. The SuperTurbo is real mild with no drone. I had one put on my full size Bronco. According to Dynomax, they have the highest CFM flow than any of the others.

--I had a "50" series offset Flowmaster with dual pipes installed on my X. It has a very nice exhaust tone with a noticeble "RAP" on deceleration..

--The only time there is NOTICEABLE resonance inside , is when I LOAD the engine and don't have the 6 sp MT in the right gear--

--Otherwise, it's GREAT

Do the Gibsons drone?

Nope not at all.... i love mine to death. Get it. Better performance, better sound (especially after a few thousand miles), and better look ..... kinda?.
