Muffler Delete

[QuickSilver]

I did it. Had it that way for an out 50 thousand miles.  I had an x pipe put in place of the third cat and I put two glasspacks right after the x pipe.  It sounded great! I put mufflers back in last week though cause I plan to trade the SHO for a new stang this fall and will get more for it from a dealer if it's quiet again...  it did drone a small amount at 1800 rpm, and was louder with more than one person in the car or when towing.  I loved it though and would do it again.

I can't believe you said that!  I did a full custom exhaust, am running a single dual 2.5"  in/out flowmaster and some strait thru resonators just upstream of the exhaust tips and I have had the drone(worst at 1900-2200 RPMS) for almost 20 K miles. All this time I thought I was imagining that it was WORSE when I had a carful of people?? By myself, no biggie but load up the Sport with 4-6 passengers and it's embarrassing :-  What causes this? Is it because the car sits lower, or the load on the motor is higher? Or?

I tried the muffler delete. The drone was ear rupturing. Then I put in a set of pypes m80 ' s. Still terrible drone. Finally had to make a tuned resonator to remove the drone. I can actually drive the car and not want to plug my ears.

I've heard about this Mod 3000 but I haven't seen it pulled off by anyone in the EB community til now, thank you for showing it! :thumb:

So many questions, where to start...  I have heard that several things affect how well its works, tube diameter, tube length, where you put it in the system(though where you have yours is where I had been considering putting mine), RPM's that the drone is the worst, etc etc etc.  THe exhaust guy who told me about this said there is a 'formula' for determining the things I listed based on engine displacement, what range of RPMS you want to quiet the drone, even exhaust gas temperatures.  Now it's possible he was making it sound overly complex because he wants me to pay him to build/install the resonator(I'm already into him $800. for my exhaust as he did the fabrication/install of the parts I sourced out) He also had mentioned that the resonator could even be a simple J shaped deadhead, that is, it doesn't even need to plumb back into the exhaust but that overall length would be critical for that kind of single inlet/no outlet, capped resonator.

Where did you get your information on size/length/location etc?  How much improvement do you feel it made, drone is 50% better, or like all gone?  Thanks in advance for anything else you can add, with 20K miles on my system now, it's way past time to deal with the drone :-[

Glad someone else finds my work useful. It isn't very complicated. The math us very simple. All you need is just a few of the variables then enter it in the formula. What I did was download an app that analyzes sound frequencies and found that my drone peaked at 118hz. So I used that in the formula I linked below. Just read threw the linked thread and it will tell you everything you need to know.

Since mine needed to be 30" long I had to loop it all the way around. It isn't very hard to fab the pipe. It's just time consuming since most shops can't bend a 180° into 2 1/2 pipe. I had to cut pipe into several pieces to make a 180.

Let me know if you need anything else!

I like Wasinger fix and my fix give you the best of both world. Stock quit for road trips with wife. And GREAT  attitude as my DD. I really think the X-pipe helps kill the drone down in my car. Oh it takes only 30 min to change them! Less if you are small enough to side under the car with out jacking it(I'm 240lb need the jack).

I went the "I've made a terrible mistake" route with the muffler delete and now chalk it up to a $1000 learning experience.  I added two "turbo" mufflers, whatever the hell those are, to where the stock rear mufflers were.  So now I have a Magnaflow Crossing Muffler in the middle and two "turbo" mufflers in the rear.  No resonator/s.

The results...

Honestly, it sounds pretty freaking good. This is how this car should sound from the factory. I'd prefer a little more noise, but it's a Lincoln, it shouldn't sound like a Mustang.  I can hear the turbos way more now too, which is pretty cool.  When I put a CAI on there (get your seal figured out AirAid), I'm guessing that the turbos will really whistle.  It's pretty subtle, with a little rumble where the drone was, and more of a "euro" sound.  I don't know what I'm giving back performance wise, but I will still be married tomorrow, so that is a plus.  I'll load some pics and video later.  If nothing else, I would have paid $300 for this no problem, so really it's only a $700 learning experience.

My set-up was $260 DynoMax,$60 x-pipe,$500 local-shop install the thing w/2.5" pipes. At LMS dyno tune of my METH. I have 405awhp & 417tor (that is 2-4hp more than the avg. METH TUNE> Total cost $820!

I thought we've already established that I should have copied your setup. Now you're beating me up with price too. Salt -> Wound.  I'm kidding of course. If anyone is going for performance on a budget go straight pipe or x-pipe with rear mufflers meant for turbo engines. Do no go the muffler delete route. It won't be different for you.

NO-SALT,NO-SALT,NO SALT!!!!! Just saying that my cheep fix works just as good as the more costly set-ups!!!!!!

I know, I'm having some fun. I wish someone else had posted "just do what shoman04 did." So I'm doing that now.

Anyone considering Muffler delete, don't. Do what shoman did. Or if you have an MKS, you might want to run what I am now. It's way better than stock.

This is the drone fix.

I'm sorry I did not tell you more before reply #31! I have given my set-up on threads and and some members(with more money than I have put my system down, because they spent more. My system give you the best of both worlds. I like my "HOT ROD" sound around town or 2hr to the track but stock quiet for road trips with wife!!!!!

Any video on what your car sounds like? My brother just did a single muffler in the middle of his 15' Eco mustang and deleted rear mufflers. His sounds pretty good for a 4 cylinder.
