Last week I ordered the JFB 4554 (that's the DI/DO 2.25" single muffler, similar to the FM Delta 40). It arrived today and am scheduled to have it installed next Tuesday - I'll report my observations.

I ordered it from their website: normal price was $39.98, but was on "sale" for $27.75. Shipping to my house was another $26.35 - a lot considering it was just UPS from PA and it took a week)....however, everywhere else I checked on the net list it for $47-48.00 plus $10, shipping, so I still got the best price at $54.10 total.

My muffler guy said he'd install it and use straight pipe out, with a custom curved tube that will capture the drone, similar to a j-pipe. I'll keep the original chrome tips.

Anyone know how long I should give the new system to "settle in"?

I am interested in your results, can't wait to hear the details, and if I am lucky, you make a video. What year is the car?

My ride is a 2012. All the Pentastar 3.6 (2011-2015) have the same exhaust, except the 2015 has different tips. So if this set-up works, it will work for all of them.

FB4554 Weight

If anyone is interested, I weighed it and this muffler weighs 10.6 lbs. The stock exhaust system supposedly weighs about 77lbs; I figure my muffler plus the straight piping will weigh about 40lbs total. The 30+ weight loss was not a big thing to me, I was just curious.

Still debating on whether I should have the muffler guy do the custom j-pipe thing or not. As I understand, j-pipes will remove drone, but also the exhaust sound won't be as deep. And supposedly the FB4554 has little to no drone.

JFB also makes a similar muffler, the V-tube, which is not supposed to have any drone. The few recordings that I heard it sounded good, but I felt the FB4554 sounded better.

Looking forward to Tuesday!

Got 'er Done!

First, sorry I don't have vids - I filmed some today, but ran into tech difficulties - will re-film and post during the weekend.

Had my muffler guy, Ron (good reputation in the Jacksonville area) install the JFB 4554 that I ordered, and straight pipe it out (reso delete); additionally, he installed custom j-pipes that he said would eliminate the drone. He advised he's done this several times for v6 Challengers/Chargers, Mustangs, and Camaros. He was unfamiliar with JFB mufflers, but advised they made good exhaust tips.

Install took about three hours, using mandrel bent 2.25" pipe. The weld points and custom tubing looked great! OK, now for my observations:

Break-in Period: Ron advised there is no break-in period for chambered mufflers, only for mufflers with insulation material; how it sounds now is basically how it will sound months from now.

Drone: None. Wait, let me clarify...my understanding of drone is it is jarring vibration to vehicle occupants and/or vehicle interior, so there was no drone. Now at certain points during acceleration and deceleration, there was an increased sound in the cabin (like a deep humming sound), but no vibration. I've experienced the same when the exhaust was stock, but now it is a little louder...nothing to complain about.

Exterior Sound: sounds good - a little deeper and a little louder than stock at idle and acceleration.

Interior Sound: overall, a little louder than stock, sometimes as quit as stock.

WOT: Niiiiiice!

Summary....

Pros: Louder and deeper than stock; no drone; no ricer sound!

Cons: Overall good sound, but occassionally it sounds like a European sports car - not a sound I was looking for.

I've only heard them on vid clips, but this set-up reminds me of the Solo (obviously) and the FM Force II, which IMHO are the best systems for less than a thousand. The difference with the Solo is I've heard it have a bab-bab-bab backfire sound when upshifting during WOT, whereas my system doesn't.

Ron agreed it sounds good, but advised that a Flowmaster Super 40 would give it an even deeper, louder sound. He advised my JFB sounds very close t the FM 50 Series (the FM Force II uses two 50's and two tuned resonators).

When I left the shop I was thinking that maybe six months from now I'd have him replace the JFB with a FM Super 40....but than I wondered if that would be too loud. As for now, I've got no drone and an improved exhaust, so I am pleased.

Next Mod: Mopar Stage 1...hopefully late spring/early summer.

Interesting write up. So what did it end up costing all total if I may ask?

Sadly I don't trust the exhaust shop near me to do any custom work. They hacked up a previous car of mine, and they don't get a second chance. I'm 99% sure that I'm going to order the Gibson catback in the next month of so, mainly because they look to use a similar 2 in/2 out muffler with resonators in the back to prevent drone. Seems like the 2in/2out muffler is pretty key to getting the sound I like.

Cost: About $28 for the muffler and about $500. for install and pipes. Sounds like a lot, but remember he added j-pipes, which I think was worth it.

Gibson Catback: I haven't heard any clips of the Gibson, but I think I read of at least two different v6 Challengers owners that were very pleased with it - definately worth looking into. IMO the best catback system for the 3.6 for less than $800 is the FM Force II, and Gibson is probably worth checking into. But I still like my mod.

Two Weeks Later...

Ok, I really like the sound - a little deeper and a little louder than stock; louder than the FM Force II, but not as loud as the Pypes for the 3.6.

Drone - maybe it's that deep humming sound I hear at cruising speed, but definately not unbearable. Eventually I may put something like Dynamat down in the trunk area, but it's not necessary. Without the j-tubes, I'm sure it would be worse.

Power - my Butt-dyno advised no power loss, and my pride wanted to say a slight power gain, but let's deal with facts: a few weeks before the exhaust install, my best 0-60 times was 6.48; today I did some pulls and the best was 6.97. I'll do more in the weeks to come, but according to this quick check I lost .5 of a second. But from what I gather, it is not uncommon to lose a little low end (or was it high end?) speed with an exhaust mod. We'll see.

Yes, I like it. A lot. :grin2:

Sorry haven't posted vids yet - my camera is MIA and I'm having problems loading the vids from my phone. My I/T Specialist (the Missus) advised that my exhaust vids are a low priority of things to attend to right now for her. I know, obviously she is wrong. I'll address that during our next board meeting.

Update: I like it it. Was thinking about dynomatting the trunk, but at this point I'm in no hurry to do it, if even I ever do it.

Did some more 0-60 runs: ran between 6.0 and 7.02. From this time and the last, I felt I had bad launches, but now I realize I launched the way I always did, just didn't have good traction. Then I remembered my tires are starting to show wear, are louder, and haven't had the great traction that had for most of their life. Not a complaint on the tires - these Hancooks previously had great traction, they're just showing some wear now (I've had them for over 40 miles, so I got my money's worth. Hopefully they'll last another 3 months before I need o replace them. At that time I'll do more runs.

I wasn't expecting much, if any, speed improvement with this exhaust mod, I just wanted to make sure I didn't lose any power. My feeling is my worn tires are the reason for the slight increase in time.

Thanks for the update. I'm having a hard time pulling the trigger on a catback. Had it in my cart several times, but just don't want to spend that much coin and not be conifident I'll like the sound. I might just spring for the JFB and give it a shot.

No exhaust change is going to affect your 0-60 time by .5 second... for the good or the bad.

It is likely a combination of factors which could include launch, DA, etc.

Who Else Did the JFB4554?

I think the JFB4554 DI/DO is one of the best options - we can only improve the sound so much with these engines. But at no point did it sound ricey. I had practically no drone, but then again my guy fabricated j-pipes where the resos were.

My experience was good - let's hear from anyone else that has done the JFB4554...

I'm considering keeping the resonators at first. Then if I didn't like the sound after a couple weeks having them removed.

I swear in all of the car work I've done in the last 25 years, this has been the most debated, researched, and fretted on thing ever. lol

LOL! Most of us don't have the time and/or money to be experimenting with this, so we want to make the best choice the first time. As far as sound, and even drone, some of it is personal preference.

Does anyone have any idea how this setup will sound with the resonators still in place? Did you leave the factory x pipe?
Everyone that did this removed the resonators, however you have nothing to lose if you want to try it with leaving the resos on first. If after a few days/weeks you want them removed and traight-piped, it should only cost around $100. additional.

Video

Sorry I haven't been able to post a video of my set-up.

The video below is not mine, and you've probably seen it on the forums over the last year; 3.6 with single DI/DO muffler straight-piped to reso delete. The guy said he had a Flowmaster (40?) knock-off, so it may have been the JFB 4554 or the Excelerator (which I hear is a direct copy of the FM 40). BTW, my muffler guy told me my FB4554 is chambered, but not a copy of the FM 40, FWIW.

Anyway, this video, as well as the videos on the Solo, sounds very much like my set-up:

Update

Been a few months now and I still like my Jones FB4554.

As I indicated earlier, my muffler guy did a custom install of removing the resos and fabricating fixed J-pipes; it looks and sounds very much like the Solo, but the j-pipes are not adjustable. Install and piping cost me about $500. Now, I never compared my system to someone else that used the FB4554 but without j-pipes, so I can't say whether these custom j-pipes worked or not. Either my custom install worked and negated the drone (so it was worth the $500), or it would have sounded the same without the j-pipes (which means I overpaid by about $300-400.). All I know is I don't think I have drone, and if I do , it is minimal and doesn't bother me at all. Only a direct comparison will tell. All I know is, I like it.

If I were to get a catback system for under $1000., I'd get the FM Force II or the Solo - I think they both sound similar to the JFB. The FM uses 2.5" piping, and the Solo uses 2.25" piping (which is the size of the stock piping on a 3.6).

Loving my Jones Full Boar!

It's been a little over a year since I had the FB4554 installed. Do I still love it?

HELL YEA!!! More than ever!

Would I get it again?

HELL YEA!!! But if I had to do it over again, I'd consider not having my muffler guy do the custom j-pipes and just straight tube it out after the muffler. Ride it for a few months and see if there's any drone - if there is and it's not bearable, then I'd have him just replace the straight piping with j-pipes. I always wonder now if it was neccessary to have the j-pipes done - maybe it was, maybe it wasn't.

Pros:
Louder than stock
Deeper than stock
Rumbles like a V8
No drone (at least no drone with j-pipes, no sure without them)
Muffler only costs $40
Doesn't sound like an angry-bumble-bee-in-a-metal-trash-can
Doesn't sound like a 4 cylinder, or 6 cylinder

Cons:
* crickets *
