An X pipe would be the way I would go...Dynamat is a great product, but you will get better results from the X pipe IMO...

 

There's a long thread here on this Magnaflow setup if you do a search. I think it's the 11385 but do a search to make sure. The dynamat recommendation ain't going to solve your problem. The x-pipe setup will not only solve your drone issue but your rasp issue as well. Added benefits are more torque and a bad azz exotic sounding exhaust.

 

Dynamat is good, but B-Quiet is lighter... I have a B-Quiet mat in my sedan trunk (HFC + Stillen Gen 1 is pretty loud and has drone)... You can install the adhesive material under the trunk mat, but I like to be able to remove it at the track for weight reduction, so the mat is my preference.

The sound-deadening product won't eliminate but definitely muffle the sound noticeably.

 

not to be an ***, but get a different exhaust. Everything else will just barely "deaden" the drone. But it will still be there. Try the dynamat/b-quiet. If that does not do it for you, look for swapping out some of your exhaust components to quieter setups. My .002.

 

Does anyone here have experience with dampers? Are they all the same, or is one better than another? Any unique designs out there that actually make a big difference? If someone could not use an X-pipe, what kind of damper would you get?

 

If i remember, I saw that Apexi made an exhaust Valve controler. Anybody have experience with these? it allows you to control the exhaust output volume from inside the cabin manually or electronically.

 

Be a man and use your *****. My gf doesnt complain about the Injen drone. She knows better

 

Hello guys.
I have the same problem with the Injen exhaust.
Too much drone in the cabin, especially towards 2000 rmp
Someone has replaced the two Injen resonators with a X-muffler? I would like, if possible, a photo: i read that should solve the problem.
This may be fine?
