How to make my accord v6 super loud and deep?

[johnnxiv]

I have a accord 2002 v6 ex coupe automatic, my budget is $1000
What header and exhaust should I get to get the loudest sound ?

any suggestion is appreciated.

Try Magnaflow, I believe they have franchises in most of the states and they can create custom systems to your spec.

Thank for answering, I have do a lot of research, and Magnaflow is not loud enough for me. I also looked at Invidia, Greddy, I'm looking to understand how to combine exhaust + test pipe + header to make my loud really loud because I have an auto so the highest RPM is like 4000

Well I have actually had a Magnaflow exhaust fitted in the United Kingdom. It was fitted to a 2 litre 4 cylinder turbocharged engine with an automatic gearbox and was pretty loud. I assume off course that with all your "Research" that you actually looked into the silencers/muffler range that Magnaflow do, as in the UK it is quite extensive?

Also, I assume again that you know that the exhaust system will make a much more subdued exhaust note after the inside of the header, muffler and pipes have become coated in carbon after a few hundred miles plus of driving?

If noise is that important to you buddy (Still unclear about the 4000 rpm as a limiting factor) then I would suggest a twin tubular header of 3-2-1 in a 2 1/2" pipe and preferably made with equal length pipes for balance. Have the exhaust made out of 2 1/2" stainless steel pipe all the way through the system. If you want to save money and make your budget go further then forget the stainless steel and just have it made out of steel. Then just forget about any middle mufflers and just put two small mufflers with tips on the end of the exhaust system.

If want to be really loud and you don't have any noise laws to contend with in Florida, then forget about the rear mufflers and just have tips welded to the end of the pipe.

Why?

If I understand correctly, your recommendation is straight pipe the car which will make the car super super loud, but I don't know if I'm going to pass the smog check or not?

I don't know much about car so I still trying to learn. My car is automatic so it will auto shift gear about 4000RPM, and maintain ~2300-~2900RPM when normal drive. So with Magnaflow dual exhaust alone will be deep but very quiet at the same time. Please correct me if I'm wrong, I watched ton of video on youtube.

I'm trying to find a way to make my car sound loud at idle too like the Subaru WRX/STI, and sound as aggressive as possible

+1 ^^^ but each to their own. If you want it, go for it.

I would get a custom exhaust made up in this case. They should be able to make it sound exactly how you want within the limits of the engine. My RB26 GTR engine was race car loud with a titanium exhaust. Soon changed back to a Nismo manufactured one so I'm saying there are limits to what the ears can handle sometimes

I agree completely. Just hope that the OP never criticises diesel engines for being noisy. :-D

 

[Aerial Andy944]

I love a loud petrol engine but in the 'real world' I've converted to the darkside of diesel and its intoxicating torque

In which case, I would suggest you have the idle speed raised to lift the sound that you are looking for when the car is idling. Obvious drawback here would be a slight increase in fuel consumption. You could still go 2 1/2 to maybe even 3" pipe and keep those small mufflers on the ends. You will want those rear mufflers to be able to be repacked so that you can alter the noise if it's not quite right.

That midrange thump is very alluring. I became addicted with a remapped 2.2 HDi Peugeot which managed about 320lbft. That's marginally more than a BMW 540i which is a 4.4 litre V8.

I'd love to get my hands on an M550d X - the tri turbo 2.9 straight six diesel. I think it's circa 600lbft

 

[T9 man]

I had never heard of this particular model before and had to Google it :embarrest:

That's quite a monster :amazed:

[SLEEPER]

you cant make a v6 like a flat four especially at idle but you can make it loud .

if you want it deeper them large bore exhaust will be the way to go,

 

[TCJBOLDIE]

How would a separate system from each bank sound??

Stereophonic or binaural I imagine

 

[johnnxiv]

so, I dont want to spend too much on my accord but I like it louder,
So i plan to only change the 2 mufflers.

So which brand mufflers give me a really loud deep sound?

 

[old-git]

Each to his own, I guess, but bear in mind that by making the exhaust loud you will probably lose power.

A classic case of all fart and no sh*t

 

[Aerial Andy944]

Had Japspeed Blue Tip Titanium system on my GTR when I acquired it. Way to loud for me and soon changed to Nismo setup. I'll try find and hook out the pics of them for ya

 

[Aerial Andy944]

Japspeed should make a specific one or universal that a custom place can weld on. This is my old one which had no muffler plates in, straight through basically. Set all the cars alarms off as I drove by

can any1 help me find a loud and deep muffler for my accord 02 v6, please?

Surely there is an exhaust shop in your neck of the woods that can point you in the right direction or a dedicated Toyota club that should have some info

It is very difficult to state a particular model muffler that will help you in your quest. This is because different engines off varying litre sizes, cylinders and exhaust manifold design all go to help create the cars own unique exhaust note.

A particular exhaust note produced on a car called (A) using a particular pipe and exhaust manifold lets call that particular performance (Loud) muffler to be used "HDT 100" this exact same muffler fitted to another different engine WILL NOT make the same noise as car (A) due to many different factors.

So unfortunately, it is very difficult for someone on here to actually state a specific muffler model number for you to buy and have fitted that will achieve the sound you are looking. Also, different people will have different views on what they class as "Loud" so what is loud to person A may not be for person B.

You really need to talk too a performance exhaust system specialist as they fit these units to varying car manufacturers products all day long and hear first hand what the car sounds like after the work has been completed, so therefore these guys need to be your first port of call so to speak.

Listen to my esteemed colleague in the above post, words of wisdom to follow.

We have given you plenty of help....

The smog laws in the states are quite strict? The only way you can have a really loud exhaust note is by fitting a straight through exhaust system.... ie. Large bore exhaust manifolds combined with a pipe with no mufflers. However, it will drone like no tomorrow and it will give you a head ache. I've done it and wouldn't recommended it to any one and that was only on a 1.4 - 4 cylinder engine! $1000 dollars will get you a decent system which will also increase power slightly and still sound really aggressive....

 

[Aerial Andy944]

^^^ +1 ^^^
Listen to us thay have been there done the straight through recovered from the headache they cause and got a system to suit the individual car now

 

[gummy]

i agree with the above my exhaust is loud,sets of car alarms etc!!,the drone gets on your nerves especially on long journeys,in one way its good as people don,t want to go in your car so you get your car all to yourself!!!.,as already said you could loose power,.I did however have a v6 capri years ago it had s/s tubular manifolds and separate exhaust of each manifold in 2and a half inch pipes with a 3 inch muffler at the ends used to sound awesom it burbled and was,nt to loud it was custom made ,i dont know who by as i bought the car with it on but it didnt loose any power.
