Interesting. I guess about what I expected it'd look like. I'm very curious to see what it does for the drone.

ankur914

I dont know about you guys, but on certain days, my drone is not that bad, but on others, is just damn near head shattering. I have a feeling i fucked up somewhere on the install, where the hangers have pinned themselves on the rubber to cause an over amount of resonance...

The inside on both has perforated metal. I think the magnaflow will make a deeper, less drone-ish exhaust note.

lol yes those are my type s OEM wheels just sitting in my garage. ive been thinking about selling them but not sure if i will.


ankur914 when did you get the cone? did you ask josh for it or did it just come in th mail?

ankur914

It arrived yesterday. It was from B&B. Im pretty sure its from Josh's efforts to address our concerns. I surely didnt expect it to arrive yesterday, but it was a nice surpise ....my only problem now if finding a damn exhaust shop in chicago that is good with welding & handling stainless steel.

If anyone is in the chicago area in need of a custom exhaust shop that welds and deals with stainless steel, i guess Iggy's Muffler Shop is it...I have no experience with them, but from the online yelp reviews, they seem to be a good shop. Im going to be going there tommorow.

Dont waste your time and money with the resonators etc, just get a mid muffler like the one thats CT cat back comes with, magnaflow makes them in the exact dimension.

j1n

iTrader: (1)

did you know it was being sent to you? i would like to get the cone if it helps.

i was thinking about getting a small muffler like the one on the CT and using the magnaflow one right behind the test pipe. but that might be a bit much. i dont want to completely silence the exhaust i just dont want drone.

The resonator cone doesn't really reduce hp; they've tested them before. It's designed to reduce resonance. I've asked BB to send all the resonated customers resonator cones.

The cone goes in the front pipe after the resonator and the tip of the cone faces the front of the car. You will want to have the cone tack welded in place.

ankur914

Well...Josh beat me to it, lol

Im hoping to get it installed tomorrow. I will definitely post my experience once i have it done.

FYI, if you google "B&B drone" - a thread about CTS's having the drone pops up. Some members installed a dynatech vortex cone in their systems and stated that it helped reduce drone. I hypothesize that these cones will do the same for us, eventhough they are not as large as the dynatechs.

Thank you Josh.

Guess i'll have to wait for the cone before moving forward with the magnaflow.

Do you guys have any idea if this cone will do anything for the "Non-Res" exhausts? Just throwing some ideas around in my head.

c2pid

iTrader: (12)

well...if you adding back the small muffler (aka mid-muffler) and the magnaflow resonator.... the only diff. is the pipe size & mufflers. you're basically going back to stock setup. my

j1n

iTrader: (1)

Yeah i know. i'm not going that route. it just crossed my mind before when i was annoyed by the drone.

i'm very curious to see ankurs results with adding just the cone.

mmmh good point this had never occured to me... I just looked at the catalog and found the following

only if it were more cost friendly... $105 is a bit much
magnaflow 14148 $105

magnaflow 14158 $105

iTrader: (12)

^^ Yessir, the first one is it, notice that it is a bit smaller in dimensions to the Comptech one so it shouldnt kill the exhaust note to a point where you cant hear it.

The above cone may resolve the resonance issue but if the exhaust is still too loud for you then get the mid muffler. The long 4/5/6" diameter mufflers dont tend to reduce noise as much as the oval shaped due to the lack of packing material depth. A 5" round mid muffler with 2.5" pipe has only 1"~1.20" inch of packing material to reduce noise, compare that to a 5" X 8" oval one which, towards the sides, has as much as 2.75" of packing material, the depth of the material is what will reduce noise and resonance. This is proved and tested with the CT exhaust as the primary mufflers are even smaller than the XLR8 and ATLP mufflers but the mid muffler is where all the noise/resonance reduction happens.

That cone is very similar to the CC Insert I purchased...below. I had it tack welded after my resonator, and it eliminated drone by 90%.

Josh (from Excelerate) said that the short oval Magnaflow mufflers won't really do much b/c they're race mufflers.

surlynkid

iTrader: (1)

so, is J1N's magnaflow the best option? is it installed yet? i want the best option, can do all the cutting and welding myself, and cost is not a concern. i need to cut the drone from 1800-2500rpm.

ankur914

Got the resonator cone installed. The drone does seem to be cut out a bit. I would say about 30-40%. Its still present, but right now, i think I can live with it. Unfortunately, chicago afternoon traffic is a bitch. I could barely hold a constant speed above 65 mph..with all the gassing and coasting. At 50 -60 mph, the drone was toned down to tolerable. Under these conditions, i found the drone with the resonator cone tolerable. And, I didnt have to really raise my voice to talk (to myself...).

Later tonight, I will drive I-94 where i can hold a 80 mph speed constant.

I have a question for you all thou. After installing this exhaust system, i find that my car doesnt like to enter into 5th gear when driving around 40-45 mph, and holds revs at 1900-2000 RPMs. Does this happen to anyone else?

j1n

iTrader: (1)

As soon as i get the cone i will get the magnaflow and cone welded on. I'm taking it to a shop that was recommended from a friend i met on here. They said they can do it when ever. they will stay open later for me if they have to, so i can go anytime during the week. I have a sound recorder and i will do a before and after sound clip. i tried to do a before clip with my wifes digicam but it sucks for audio. thats why i never posted a vid of when i first got the exhast on.

Thanks for the update on the cone! im very confident in killing the drone with the magnaflow + cone.

40-45 is ussually when i shifts into 5th for me. when im decelerating it ussually down shifts at 39/40 MPH to 4th.

dunno I think the mufflers jnc mentioned might work... best bet would be to install one on a non resonated setup and have a user review it...

I have seen those race muffelrs in person... and it was on a straight pipe 3" k series civic... wasn't that loud... weird

andyc123

Gilla, where are you? I replied to your PM, am having the same issues. I already have a high flow J-pipe (ATLP V2) so your drone is at least as bad as mine.

Let me know what happens on your install if you get the MagnaFlow. This drone sucks.

How recently did you ask BB to send them? I need one!

I'm here! I'm waiting to see how j1n's 22" magnaflow muffler works out. If it doesn't help out much, and there is room under the car, I am going to install the Vibrant ultra-quiet resonator (basically mid-muffler size.

anyone else get the cone yet?.... im still waiting.

Some times when I am in the car by myself, I forget to put the music on b/c I am in an exhaust drone trance. I do realy like the sound, except when any of the other 4 seats are filled.

I'm gonna jack the car up this weekend, take some measurements, and then order THIS, assuming it fits somewhere. Even if the cone arrives before, I'm not gonna stick it in. I'd rather not put a restriction right in the middle of the pipe.

ankur914

You going to cut out the original resonator and put the magnaflow in its place? or stick the magnaflow somewhere upstream (or downstream) of the original resonator?

TheChamp531

iTrader: (3)

You guys should've bought the Comptech Exhaust and slapped on a Aero Resonator, very little drone, and at the same time not too loud in cabin. Anyways, I find it funny that one user said he had customers in his car with an exhaust... If you're going to have customers in your car, don't buy something that will make more noise.

j1n

iTrader: (1)

What are the specs of the resonator? it doesnt say on the site.

i know what you mean. i dont mind it at all when im by myself... mostly because i barely hear it anyways cause im bumpin my music. but when i have passengers and the music is down and your trying to have a conversation the drone is annoying.

I'm going to cut out the original resonator that came with it cause it is TINY and i dont think it really does anything. put the mangaflow in its place and add the cone right behind the res.

i will post before and after audio clips when i do it...... im still waiting on that cone!!!!

andyc123

Okay, so I have to put my 2 cents into this, being that I have the Xcel Resonated version. Every fix I look at seems to restrict flow. The CC inserts have a small interior and holes on the outside, and the cone is, again, more metal with some holes.

Excel says it's been tested so I'll try the cone (if I get it). I'm a little hesitant to put an additional muffler on. We bought this type of exhaust to get more flow and hp to begin with, so I'm waiting to hear from everyone who straps on their choice.....

tihomirbg

iTrader: (1)

I don't know if you got the res version or no res, but I got the non res. I have been driven the car 3 times so far since I did the installation. the more I drive, the more I like the sound. I would not change a thing for right now. My only complaint is between 1500 RPM and 2000 RPM. It is not that bad but I don't like the sound so much when in the this RPM range.

Just a heads up. This is the most recent update from BB:

Joshua,

I submitted the list of customers that need to receive a resonator cone. The cones are being cut out now and should all leave by Friday.

surlynkid

iTrader: (1)

Josh - see my post in the GB thread about this.

gilla_monster

iTrader: (2)

The Vibrant resonator is 2.5" inlet/outlet (obviously) with overall length of 14". Resonator itself is 4.5" x 6.75" Oval with 10" body. It's basically the mid-muffler that we're looking for, IMO. I'm gonna leave the resonator alone and put this downstream, assuming it will fit downstream. It is a straight through design, eg: no physical path restrictions like the cone.

j1n

iTrader: (1)

Ankur, besides less drone did you feel any other differences when adding the cone?

ankur914

Sorry for the lack of input, but heres the rundown of the effects of the resonator cone.

On cold startup, the drone is not annoyingly loud anymore. Before when i used to start up the car in the garage (with the damn door open lol), our dinner plates, wall fixings, and such would rattle in the kitchen (attached garage). After the cone install, not so much.

The incabin drone of cold start up is also significantly reduced.

Prior to the entire exhaust installation, i had a vibration free car (after one dealer visit to cure the rear deck rattle...which by the way, Libertyville Acura rocks). After the exhaust install, pre-resonator cone install..well...There were too many rattles that i couldnt count. ONe in the center console, one in the passenger side door, one in the drivers side seat belt pillar, another in the damn dash which seemed to be coming from way inside the dash.

Well, after the resonator cone install, all the vibrations aside from the center console rattle were all eliminated. Less resonance produced by cone downstream of resonator is what i surmise. Additionally, when crusing at 80 mph, i dont get a headache. Dont get me wrong, there is still low frequency drone present, but it doesnt feel like your head is going to pop off. I can enjoy music at a volume of 10 now also.

In terms of power loss, the ole butt dyno didnt feel any sort of loss at all. Still very peppy and for some reason, still struggles to get into fifth gear when around 40-47 mph (rpms hover around 1800-2000 rpms). This shifing issue was noticed after i installed the exhaust. And no, i did not disconnect the battery, so this may be the underlying issue (but after 200 miles, youd think the comp woulda relearned any sorta change...oh well).

Many people stated that after the resonator cone was installed, the drone was not annoying anymore. It is now definintely tolerable, and at times, nice to listen to. People can hold a conversation in the car as well.

All in all, i now love the exhaust. I dont think i would change anything on it. It sounds great outside of the car, and pretty dope on the inside. I will say that after 200 miles, i have started to get used to the sound, but the resonator cone did make a difference. I hope this helps in evaluating your decision.
