Quiet Exhuast for K Series

[IN73GZ]

hey guys i wana know if any knows wat mufflers u can get that will quiet down a k swap, im gettin a custom 3 inch exhuast all the way through for performance benefit but need a recommendation for which muffler i can use which may help keep the car a little more reasonable for daily driving.....

[GIPONU]

customer at this mechanic i work at got a 5zigen pro racer exhaust system installed.. it was pretty quiet. under 90db..

whereas when a pro racer exhaust was installed on my mates silvia s15 it sounded louder than 98db..

[PaZzMaN-R]

i think it was best motoring which did a test on muffler db readings, il try find them

[JasonGilholme]

Is your setup NA??

If so, isn't 3 inch a bit big??

Probably best off with a 2.5 or 2.25 inch. Also i've seena company that make headers for the k series which lin up to the standard exhaust system of an integra/civic..

I think it was hasport. i cant remember. but i'll try to find it.

[dc2dc2dc2]

3" is turbo style !

thats massive dude....i think ur gonna lose power.

[flipstar]

^^ yeah JasonGilholme is right 3" is a bit big you would lose back pressure and high end torque as well if its n/a my mate got a toda and its pretty quiet even after vtec kicks in but its got a great purr 2 it

[bennjamin]

3 inch isnt too big for a 2.4l :)
Especially if its made to rev....

[hinezz]

try magnaflow mufflers, they are gud :) best size for K24 N/A is 2.5" if ur going to boost it then 3"

u will lose power if u plan 2 keep it 3" for ur NA application :)

[IN73GZ]

your saying 3inch is too buig however i didnt mention im doin k24 wiv k20 head, not just standard k series, recommendations from jdmyard and other reliable sources have recommened 3" for peak performance not 2.5"
regardless that wasnt my question, im asking for quiet muffler

[[ricer]]

how many of u ppl that are saying 3" is too big actually drive a k24 wiv k20 head, recommendations from jdmyard and other reliable sources have recommened 3" for peak performance not 2.5"

thats right
yonas should know what his on about
last time i heard egk20a it wasnt overly annoying loud
it had a very niceeee tone...

have u heard it?
its just a oval xforce muffler

[PaZzMaN-R]

mugen twin loop
idle 60.3
stationary 88.9
racing 94.9

[destrukshn]

that's the difference between idle and stationary?
lol.
both means your in one spot.
lol.

[civic_mods]

if i m not wrong the test was done at idling rpm, stationary at 5000 o 5500 rpm

[destrukshn]

there stationary at 5500rpm?

[Chi]

With DC5Rs, when u hold Accelerator on stand still , it revs and holds at 5k rpm

Not sure bout other K series.

well i tell u what mate, Magnaflow mufflers are good but theya re also very ****ing loud. I have a magnaflow muffler sitting in my shed. its the one with two 3" trumpet tips on it (very loud when high rpm but sounds sooooo ****ing good)

Get a mugen twin-loop man. I have one on my dc5r and it is so quiet. It's all engine noise baby!

u hear nothing from this zorst! not in the cabin anyway, has a deep subtle noise on the outside though

[Perry]

just add a few resonator?

[EG5]

go to westside mufflers , they did quite a few of custom 3 inch catback for egk20a , egk24a , badhbt , car80y etc

[hinezz]

what sort of muffler does it have?

[didz]

if uw ant quiet, dont get a cannon unless it has a silencer on it which is pointless anyway. Just get a twin-loop if u want noise reduction.

i've personally heard cars with big fat cannons.
being very quiet.

were they turned on?

[destrukshn]

just because YOU haven't heard one, doesn't mean they don't exist.
any more stupid comments?

[didz]

lol... FIRE UP!

I think it would be fair to say that on average in most cases a cannon is loud.

YES OR NO MATE, YES OR NO.

thats what i thought.

[destrukshn]

lol, did you say that in your first post?
NO.
=)

[aaronng]

^^ that is very bad advice. Either that or you are spamming in the tech section.

[simonnowis]

hey in73gl have you sold your b18c?
anyway, yeh id go with twin loop, they are really quiet. i have the s10 xforce and its really quiet not very noticable. alitte louder in cold weather.
or you could put two hotdog resonators on and which ever muffler you like maybe hks style.
maybe two hotdogs and a twinloop. hahahaa

[xtercii]

this guy is asking for a quiet 3in exhaust and all you guys are giving him these pissy weak little 2in and a bit suggestions...

he's not asking for what exhaust should he be getting, I am sure he's done enuff research to decide what's the best size for his set up.

[fatboyz39]

3' is the right size for 2.4L. Don't think there is a pre made exhaust for k swap in dc2. remember to get a good muffler and put 2 good resonator. Don't think it'll be that quiet due the the exhaust size.

[IN73GZ]

thanx 4 the input xterci n fatboyz, first 2 ppl that have actually payed attention to my initial question

so far looks like having 2 resonator and yeh possibly twinloop exhuast aswell

[yourfather]

Wouldn't any muffler that is say JASMA approved and 3 inches in diam going to be sufficient.

i.e. if there is a GTR exhaust that is 3 inch and JASMA approved, would that help.

considering that the GTR is a twin turbo 2.6.

you'll need resonators too though.

[NeoBlue]

I have a Trust Power Extreme II exhaust and it is pretty quiet for both idle and accelerating. Pretty good and solid exhaust..

[yourfather]

do you have a K24 Hybrid DC2 also?

[IN73GZ]

lol hahaha

go to westside mufflers , they did quite a few of custom 3 inch catback for egk20a , egk24a , badhbt , car80y etc

Is that the same exhaust system that is fitted on car boys original k20a?
The 3 inch system is definetely the way to go

[twofruitz]

I have a full Trust system and its incredibly quiet between 0-4000rpm... after that it sounds nice and loud.

[BADHBT]

. there are no company that has released a 3inch exhaust for hybrid swaps
. if you want a straight through system it wont be quiet
. imo it wont be easy to fit 2 resonators in the system, as the collector ends est 5 inches before the shifter box as well as fitting a flexi and a cat, unless running a smaller one on the second bend
. you can get a custom muffler made to your spec but that wont be cheap either

[aydo14]

mate you should go xforce twin loop (s10) with an extra resonator
would be quiet as

[EG5]

different muffler , different resonator compared to the old car80y

[EG5]

mate you should go xforce twin loop (s10) with an extra resonator
would be quiet as

twin loop max out at 2.5 inch

[tectalk]

i don't understand why wouldn't u get a 2 3/4inch exhaust that way you would be able to get a little quieter one but still have performance :) also thats what im getting on my k20 :) so if anyone can recommend a awesome 2 3/4inch that would be awesome.

[BusterSonic12]

i'm currently tossing between RM01A n HKS but dont know how big they are tho.
