Hi, Stangers:
:doh:

I have this set of modded MAGNAFLOW COMPETITION (19179) axle-back exhaust for 15-17 V6/ecoboost, it's professionally fitted with side branch Helmholtz resonator on both side of the muffler.

Magnaflow competition has the highest price in the market both axle back and cat back systems for v6 and Ecoboost, and that's for a good reason. It has the most aggressive and DEEP tone of all brands.

However, the drone in the cabin is pretty huge, some people even refer them as "magnadrone". this side branch Helmholtz resonator was meticulously calculated and professionally welded, and after testing, it eliminates 95% of the Drone!!! without affecting the tone of the system

More information about the most effective drone canceling please google/youtube search:
side branch resonator
Helmholtz resonator

Cat back portion(resonator) will come with the system free of charge,
NO RASPINESS
;)
NO DRONE
;)
NO WORRY
;)
NO FITMENT ISSUE


The deepest tone of all for a v6/Ecoboost and custom fit, no change to your car needed, like new condition (about 270 miles), free resonator and connecting pipe. bolt on ready!

Item located in Maryland, ready to ship for the mid-Atlantic area. 400+shipping
you can check out the price, see the value of the deal.

Curious, any videos of it? I can't find any videos of anyone who has done this.

How come you're getting rid of it so quickly?

Why use a resonator on the j tube when just the length and the cap would have been sufficient. Just curious seems excessive. Do not get me wrong it if works better than just the basic J tube setup, seems like it adds so much more weight..

I do have a video that records an in-cabin sound after the side branch resonator installation if you want I can send it to you. didn't videotape the outside sound, that should easily found on youtube. And the side resonator doesn't affect the outside sound. I was just after the drone canceling.

Such a shame I'm back to stock now, basically, it's the loudness of the competition muffler itself. I'm doing this for my girlfriend, she always complaining that this is too loud and unrespectful blah blahs, I didn't listen, but we found out 3 weeks ago that she is PREGNANT!!! YES I'M GONNA BE A DAD SOON!! She said the loud sound makes her frightened and look/sounds stupid, and makes her dizzy after getting pregnant. So guess what?

bought 2 adapter piece online and 4 clamps. soon-to-be daddy back to stock.

simple job a J pipe can do, but with a thin resonated pipe,
It has its only purpose is make the sound deeper at higher rpm

I assume you are in Iowa? It depends man, I think there are different logistics option available, how fast you want them to arrive to you? and do you need that factory resonator w/ piping as well? or you can just cut your own?
I can give you measurements if you want cut your own.

No rush on shipping, and I wouldn't need the resonator/piping as I'm still running stock exhaust.

If that's the case, a UPS ground won't cost much, even with the foam bed premium packing (I don't want any damage to the system especially the 4.5inch tip) I think I'm confident it'll be within 100 for total packing and shipping cost
