Update DRONE.......

[mecry][facepalm][?|] The way my system is set up has caused Allot of DRONE. I have used Sound Deadening Material in the Spare tire well and surrounding areas with little success. I almost think I made it worse [facepalm] I will be doing under the rear seats later as I still have allot left over after I get the drone fixed.

I talked to my exhaust shop and they will be installing a J-Tube to help lower or completely illuminate the Drone. I looked online and found the equation and I came up with about 20" but I could go up to 23", I'll be trying to get an adjustable one to find the best length. That's with the drone at about 2,500 rpms.

Just keep in mind my system was modified differently then the normal system and I wouldn't anticipate any on and un-modified system.

I Still love this system [hihi][thumb] and the deep tone.

Ok, Ok, Awww....

[bigcry][?|][B)] Ok, my drone has not gone away at all. I've finished installing the "J" Pipe at 19.5" from doing research on here and other sites regarding drone and length of pipe. This did not help at all. [facepalm]

I installed Sound Deadening Noico Black 80 Mil from Amazon in the spare tire trunk area and also under the passenger seats, it didn't do anything either. [confused]

Now I'm on my last leg and will be putting in a Magnaflow 12265 Muffler in the rear replacing the "Y" pipe and see if this helps. If this doesn't work, I will then have the 2 mufflers taken out and see what it does with just the Magnaflow.

I would suggest NOT getting this system if it's going to be modified like mine to fit the Focus. I think the drone is from the Custom "Y" pipe they did after removing the mufflers. The main system has the "Y" pipe running into the mufflers and then exiting out the back. I believe removing the mufflers created to much of a restriction and is causing the drone.

I just ordered the 12265 from www.AutoHance.com as you can get an extra 10% Discount on Magnaflow mufflers. The reviews were really good and I'll keep you all posted on my "Drone" Exhausted system.

I know, I Know, but I still love the sound from this system and would highly recommend the "STOCK" format for the Focus and not getting it modified how mine was. Overall I love the Deep Throaty sound [thumb]

EDIT: "APE" Arkansas Performance Exhaust did an Excellent Job and they are in NO WAY associated with the DRONE Problem I'm having. This is just the "Nature of the Beast" when you put in a system that was not made for the Focus and when you have modified the Rear Bumper that causes issues with the placement of the "Stock" system you want installed. I just wanted to make sure that everyone knows this was my choice and I'll get it corrected.

Good Bye Drone...

[headbang][giddy][cheers] Well, I had "APE" install the Magnaflow 12265 Muffler and all I can say is [grinking] WoW! It killed almost all the Drone except for the WOT!

This drone will always be there as it's a hatchback and everything is open from the back to the front. It really quieted it down, but it still has a low rumble that sounds really good. I still have the 2 mufflers, tips and the 2.5" piping from the original kit and I think these help with the low rumble different from just having the Magnaflow muffler. I'm very impressed with how it sounds and how much the drone has been stopped.

Looking inside the muffler it's just a Y Pipe with stainless steel stuffing to help quiet things down. Granted this muffler; Magnaflow #12265 is a Firebird, Trans-am, LS Camaro muffler. I would highly recommend this muffler and the 2 mufflers from the original kit. I just have NO Idea what type or who makes the mufflers from the Mazda kit.

To that end, my saga for a good sounding Exhaust system [hatchet] is done and the dreaded Drone has ben vanquished [drinking][cheers]

Oh, I forgot... It pulls harder now then it did with the original Mazda kit. I'm still just putting miles on it and we will see if anything changes in the sound, drone or if it really pulls harder with this set up I have now.
