Buddy Club Exhaust (spec 3 or 4) vs. Twin loop exhaust (mugen or xforce)

[Dau]

hey...i drive an ek4...and im not sure which i shd get...either da buddy club or da twin loop exhaust...

whats the pros and cons of each? and if buddy club...spec3 or spec 4? if twin loop mugen? or xforce?

[PaZzMaN-R]

BC exaust loued and big, mugen or xforce twin loop silent and slightly hidden and small.
are they going to be full systems or just mufflers?

[czy_sol87]

the BC "spec" exhaust are catbacks, and are very, very, very loud, they have no restiction, ie straight pipes
and if u are unforuntate enough to be pulled over by the police, u will! be defected for it and there is probly no way of avoiding it

on the other hand the mugen or xforce twin loops are just mufflers, u will need a b-pipe, and axel-back depending if it comes with one, if u want a full cat back exhaust
these will be more quiter and will attract less attenion, however u might not get as much power as the BC because there will be ristrictions on them to keep it quiter, ie resonators, and the end muffler

[[[d a n n y]]]

i had twinloop on my car it was too quiet for my liking now i got a BC spec 2 on my car now i am going deaf but i love the sound it's up to u man. deaf or too quiet :D

BC3 rocks!

[Encor3]

twinloop provides more torque, but yes its a pain in the arse to get an axel back or bpipe, currently looking for one =)

srry just hijacking for a sec
is thier a big difference with or w/out silencer for the buddyclub exhuats or are they about the same noise level

[eriktufa]

There will be a big difference when you use the silencer on the bc3.

Out of all the exhaust system, I really recommend BC Spec IV as this exhaust compromise both noise and power, as the power output shouldn't be much different with BC spec III as both exhaust have ID of 2.5 inch.

BC IV will be fairly quiet (not as quiet as Twinloop) under normal driving condition and it will be super loud when you race the car.

While, BC III is really loud :D

Hope that helps

[RIVAL]

lol sure does is the bc IV the one with the really short canon tip

[Encor3]

because of such a small engine, there isn't alot of torque and having a twinloop i dont know the mechanics of it but just been told over and over again by various people, a twinloop will increase the back pressure or something and allow more torque.

having heard the buddyclub exhaust... its pretty loud not my sorta thing

[air23box]

Mugen Twinloop
Great low end torque coz it run around the loop...by increase back pressure....your engine will privde more low end torque but it doesn't mean they are restrictive on high end. Because the design in the loop...there is a valve that will open up in high exhaust pressure and make it like normal exhaust....thats why they will become louder when you Vtec it...
X-force
Same design as mugen but you know the price difference.....you get what you pay for...
BC Spec series
They are not straight pipes except spec II...They all come with hotdog on B pipes.....but the reason they are louder since the material they use and also the pipe itself is thinner.....They will provide excellent high end improvement but you may lose a bit of low end torque coz of lack of back pressure.....
Hope that helps.....

[sivic]

are you sure there's a valve inside the twin loop?

[Encor3]

im pretty sure my one has,

[F.O.B Squad]

man i rekon go the buddy club if u wanna here it scream in vtec espec bc spec II. sure it mite cause a lil chaos on da road wit cops nd stuff but dats wats its all about man. my m8 got 1 on his, nd its only a d series vtec nd its freakin screams man. up 2 u tho.

[yourfather]

fully sik man....

farq, its kaos wit da koppas..
polis pigzzzzzzzzzzzz

p.s. just get somethin thats in the middle. you dont want to go deaf by 25.

rofl... joeseph jus get ur self somethin in ur price range =P btw check ur email

[F.O.B Squad]

ahh yeah ok den well check out da buddy club website anyway nd dey got da db test on how loud der exhaust's r.

oh nd ps. my m8s asian not muzza so no fully sick business crap. wats wit da stereotypin. no vl turbs here.

it's not back pressure you want to produce low end torque, it's a balance between flow and inertia. Back pressure is evil in every way and is to be eradicated

Large pipes mean the gas flows slower (try blowing air through a straw, then a toilet roll), and as the gas at the outside of the pipe sides encounter friction from the pipe walls, it slows, the faster gas running on the inside causes eddies to form along the pipe wall, which actually encourages the gas to start flowing back up the pipe (fill a sink with water and pull your finger straight through it, some water will go in the opposite direction). In that situation, the exhaust coming out of the motor is basically encountering a very small area it can flow through, hence no torque.... but at high RPM the sheer volume of gas doesn't allow this backwards flow to occur, the larger pipe allows more gas to be pumped out of the engine, so better performance

A smaller pipe will allow more flow at low RPM because the overall speed of the gas doesn't allow the eddies to form.... the exhaust coming out of the port encounters a larger area to flow through...

Now, add on to that the inertia aspect - the gas flowing out of the pipe must push something out of the way - resistance from the air already in the exhaust, and actual back pressure caused by restrictions in the system - but as it pushes through, it creates a vacuum behind it, effectively sucking the exhaust out of the head. The bigger the pipe, the less inertia the flowing gas has, so less vacuum...

exhausts for turbos are a different story ;)

I'd like to know more about the mugen twin loop and the valve thingy, I've searched and searched and the only mention of it is fokelore on forums like this. The twin loop design seems to be all about soundwave tuning - using special sizing and angles for the pipes to eradicate unwanted sound waves, while allowing the gas to flow.

Look, I know that it's "easier" to type like that...

But we aren't in high school anymore.

Cool!!

[air23box]

yeah...do a search in the mugen website...you will find out more...as I am using twinloop on mine....

got a link? the only one I can find is www.mugen-power.com, and the japanese version is pretty useless, and the english version says "Sorry. English pages are currently under the constriction" lol...

[mimps]

BC3 is loud, but u get nice gains from it.

go to parts....and exhaust.....click on sports exhaust system and click on twinloop image....then you can see how it works...

[jords]

I got mugen 4-1 and mugen twin loop and its not overly loud (only when in vtec), and makes the car breath a whole lot more.

[gelo]

also...mugen comes as a catback
