I used to have a 06 TL and you guys are smarter than the other site for accords so I thought id ask ya. have a 08 3.5L 08 accord. I find the exhaust system seems very siliar to the tl, correct me of i am wrong.

I recently put 2 magnaflow mufflers on the accord...the problem now that they have a very deep low tone that drones through the cabin. I am not please with the exhaust note either. I called magnaflow. They said remove the front res. They suggested this because they claim the current exhaust note is low and deep because the resonator is restricting the flow of air.

So what should I do? I thought removing the res would make it louder and droner. PLEASE HELP I AM SO LOST HERE.

you could remove it or just replace it with a vibrant/magnaflow/etc type resonator and it would probably help. All the J motors seems have at least some amount of drone but it has certainly been managed by most in the past.

I would do some youtube searches and see if you can find a setup like yours with no resonator or a different resonator.

tell us more about your setup. from the engine back what's been done?

davewhodavedunn

The only thing that has been done are 2 magnaflow mufflers welded on. That is it.

If I use a vibrant or magnaflow res what will this do for me?

Like I said the tone is super deep and just not throaty plus it drones. Also I loose exhaust tone over 4000 rpms. Apparently this is normal with magnaflows mufflers.

I have done youtube research with no results.

davewhodavedunn

Again my exhaust tone is pure bass, pure loud deep tone with no throatyness.

pure bass huh? would you say its more bass than the stock sub can produce?

davewhodavedunn

Always a shit talker on acurazine. Wow I really dont miss this site.

I was trying to describe the exhaust note as its not raspy not throaty but just a deep hum, sorry it wasnt up to your standards. Glad you have enought time on your hands to write dumb shit instead of helping a fellow old member.

davewhodavedunn

Any other opinions? I really want to correct this prob.

Ken1997TL

Just ignore people rather than fall for their bait.

Which magnaflows do you have installed?

davewhodavedunn

I try to ignore stupid people, and when I had my acura I dealt with ppl like that all the time but only on this forum. Alot of people on this forum are helpful but there are alot of shit talkers who just come in and have nothing good to say and don't help.

I have the Magnaflow 14834 mufflers

Below are the pics of the set up. Again 2 magnaflow mufflers welded on.

So I need a answer like asap cuz I am about to buy either a TEST PIPE or a MAGNAFLOW RESONATOR to correct my deep boring tone to my 2 welded on magnaflow mufflers...Again I only have 2 welded on magnaflow muffler 14834 Below is a youtube video of what I want my mufflers to sound likes...which one of these will give me this tone...

i have a magnaflow resonator and a straight pipe where the mid muffler was and my car sounds similar to a g35 (deep and no rasp). not sure if that was what you were aiming for.

no exp with test pipes so hopefully someone else can comment on that

Afgkid11

maybe the the silencer,and the mid muffler should be removed, and maybe the the part that you wielded it that the there is different diameters with the exhaust piping.

dude i wasnt even talking shit, i was making a joke -_- maybe the age difference of people on this forum is too wide, for example a 30 year old may not understand the jokes of a 20 yr old.
(not to say im 20)

back to the topic....dont get a test pipe if you are looking for less drone, and i call bs on the removing front resonator, a lot of times the ppl who work there dont know what they r talking about. add one of those vibrant resonator things that might help however keep in mind a v6 will always have more of a deep sound (compared to an I4)

davewhodavedunn

The reason I would remove the front resonator and replace it with a magnaflow resonator is to create more of that throaty sound. Magnaflow themselves suggested it and said this would increase flow. They claim I would or might experience more drone but that is to be expected. I sent them the video I posted above and they said adding there resonator would make my car sound similar to that one.

So does anyone have experience adding a magnaflow resonator to the oem exhaust system with 2 magnaflow or other mufflers welded on the rear?

davewhodavedunn

So i am going to install a magnaflow resonator to replace the oem resonator. I just dont know which size the oem 08 accord 3.5 v6 sedan piping is. Any ideas?

vibrant resonators... no drone

paperboy42190

iTrader: (7)

should be 2.25

davewhodavedunn

I need to know for sure. Everyone thinks 2.25 but they do not know for sure....can someone help me? I am desperatley trying to find this answers out so I can order the resonator asap. I dont even have my car with me to measure

Sonnick

You should honestly just wait until you have the money to fork over for bigger piping. Get a 2.5in midpipe, either a Vibrant or Magnaflow 18in resonator, then 2.25in piping at the Ysplit back to your mufflers and call it a day. It will sound 52x better than it does now and you will get some performance out of it. Those mufflers look really good on the back btw. Magnaflow tips too?

EDIT: I just serached that muffler and it's a 3in muffler. Should've gotten a 2.5 or 2.25in muffler for that section. But in that case, get a 3in midpipe. You're going from 2in to 3in. That's part of your sound problem too.

The mistake you made was going the cheap route and just welding on magnaflow mufflers when you should have gone with a magnaflow cat-back setup.

davewhodavedunn

Theu dony make a magnaflow catback for the sedan.

davewhodavedunn

The reason i got the 3 inch inlet muffler is because i was sent the wrong ones. I wont be getting bigger piping i just bought a house no money for that shit no more, i am just going to add thee magnaflow resonator at the front and call it a day. This should help for sound correct?

EL19

iTrader: (4)

Well theres your dam problem, you put 3" inlet mufflers on 1.75" piping. Theres not enough air entering those mufflers and its creating the drone. I suggest you either A. lay off the chop shop exhaust and get mufflers that match or at least close to the stock piping or B. fork over $360 for the magnaflow catback that almost EVERY 8th gen accord driver has or C. Replace that stock piping with piping that is close to those mufflers you have an add a resonator. i suggest 2.5"

Also head over to my8thgen.com. A select few members over there know ALOT including myself.

davewhodavedunn

magnaflow does not make a catback for the 08 accord SEDAN...I asked them trust me.

I went with the 3inch diameter because the magnaflow tech was an idoit and told me to get the wrong one. So my "hack shop" lol used reducer making it almost the same thing as a 2.5 or whatever.

The fact is the exhaust isn't droney...its just very deep sound with no throatyness AT ALL....Magnaflow knows my set up (oem everything except welded on magnaflow mufflers) and suggested either removing the front resonator (shown above) or replacing it with there resonator 2.25 14 inch long. They said this would help the car breath better and I would get a similar sound to the video that I posted above.....

so what do you think?

phee

iTrader: (5)

Get wider piping.

davewhodavedunn

omg lol...cant anyone understand I dont have the money.....I dont want performance just sound that is why magnaflow told me the best opton is to install there resonator which will create more flow, or just straight pipe the front res.

All I need to know is what either will do.....

Dave_B

If you're looking for final answer, forget it. For one, you're on a TL site. Different motors, different exhaust designs, the list goes on. Two, you're doing an awful job of describing the exhaust sound while doing an excellent job of getting pissy. Three, you're going to have to stop taking a vendor's recommendations as the written Word of God.

If you're an automatic, that is a large part of your problem too. Torque converters slip during most driving, don't sound as athletic or throaty, and ultimately cause more drone than a manual. It's a sound quality you're going to have to live with. There's no real way to make the motor rev quicker like a manual that has a direct connection to the engine and typically deeper gearing (ie more shifting).

If you want to know the exact size of the exhaust piping, you're going to have man up, get the car on jack stands and use a measuring tape to wrap about the pipe in question and then use math to find true piping diameter.\

Changing out resonators may help somewhat, but it's going to take a lot of experimentation to find the sound you're looking for. Chances are you're going to end up creating rasp and hiss if you start adding less insulated resonators. BTW, the resonators are not restricting flow. Silly Magnaflow guys.

delete both factory resonators and run the longest straight resonator magnaflow makes

worked for my daily driver



fyi since your mufflers are 3" you really should just do single exit
everyone will think you have a 4banger... till you stomp it

phee

no money = no mods.

fast, reliable, cheap. pick any two

davewhodavedunn

Im gunna run the factory front res and replace it with a magnaflow resonator. See if that gives me a throaty sound. The mufflers sound fine noe but just want a g35 is sound as opposed to just a deep tone.

greco9885

iTrader: (1)

Then buy a g35 guy

TheChamp531

iTrader: (3)

We bashed you before cause you never searched.

Secondly, just put your car back to stock, sell the mufflers, and do it right the second time.

ParaSurfer1979

You other real problem is that the Accord's V^ isn't 3 stage vtec. It's only I-vtec because of the cylinder deactivation. If you drove a TL non Type-S you'd swear the 258hp motor had more than that. The tone isn't throaty like the TL's smaller 3.2 motor because your motor doesn't have vtec cams to give nit that sound. Want a throaty sound, leave the exhaust as you have it and do Intake and J-pipe.

davewhodavedunn

I had a TL. I found it slow and the heat soak was crazy and in the 3.5 I find NO HEAT SOAK...I do have a intake and I dont know if I j pipe will change the tone. Magnaflow is sending me this resonator to open up air flow and change the tone, they swear it will. I will keep ya up to date on it guys. Thanks for the help. I have taken it all into consideration. Keep in mind I did this mod for look and sound only...didn't care bout more power. I am happy with the 3.5L 271HP plus the intake....

EL19

iTrader: (4)

Weird you found the TL slow. The 3.5 in the auto 8th gen Accord is slow as shit. Any TL from 99 to now would keep up with it if not beat it. The 3.5 in my 6MT Accord was the truth. 285whp with 3 mods(Intake, PCD, Jpipe) on stock catback. 13.9 1/4 mile stock. Only thing that car needed was an LSD and it wouldve been great

But in all honesty, I would get rid of those mufflers. They are the root of your problem. The resonator isnt going to give much extra "flow". Getting a jpipe on the other hand will give you much more exhaust flow. Many 8th gen members have added the jpipe and reported having less drone.

In regards to the 8th gen SEDAN having a catback. All you had to do was buy the coupe catback and add a couple extra inches of piping. been done numerous times. Ihope you get what you need. Having an exhuast sound you dont like blows

ParaSurfer1979

He's EXACTLY right. The Accord does 0-60 in 7.5sec when even the 3.2L does it in 6.8 and TL-S auto 6.2. In your case a J-pipe would help. It opens up the exhaust with larger piping from the engine to the cat. Hi-flow cats would also change the tone. Your car is still bogged up in some cases that can improve the sound if replaced but that said it'll never have the aggressive tone of the real VTEC motors in the TL/Accord V-6 6-speed. i-VTEC in the V-6 accord should be called Vtec-E. It's an economical system vs. performance.

davewhodavedunn

When i had my 06 tl i removed the oem front resonator on a completley stock muffler system. It was great it had a nice throaty sound so i was thinkin if I do this with my 08 accord now that it has magnaflow mufflers welded on it will do a similar thing. That is why magnaflow suggested there resonator. This they claim will change the tone and make it aimilar to the video above. Keep in mind guys i just want a change in exhaust note not performance.

Sonnick

I'd go with Stillhere's idea. Take both of the factory reso's out and put in a long Magnaflow 4in or 5in round muffler (18-24in long) and you should be good.

What you should've done, was send the mufflers back to Magnaflow when you realized they weren't the correct diameter. Then waited patiently for the correct mufflers. It would've saved you time/money since you are looking for ways to improve it now.

My moms 4dr Accord V6 actually feels pretty quick. At least from a 20mph punch in 1st in manual mode. The power delivery is shockingly smooth.

davewhodavedunn

18-24 inch res? they want to send me a 14 incher
