I have posted about this in the past but dont you v6 owners find the induction roar to be a bit on the tame side?

I fitted a pipercross open cone on mine and i still found it quiet compared to previous cars i.e - vectra v6, fto v6, clio valver, golf vr6.... why is it so quiet??? is it something to do with the variable intake system or the actual manifold itself as i remember the veccy gsi had a butterfly type inlet for power but sounded awesome with a ramair filter fitted.

Opinions welcome :) zs180 is way too quiet.... need some v6 induction roar

two vids do sound good but here is my argument... heres my zed with a piperx cone fitted and a powerflow catback

Now heres my old vectra with a ramair and irmscher exhaust

And my fto gpx with itg and zorstec catback

http://www.youtube.com/watch?v=G8BuW86EYfI&feature=plcp

The zed sounds lame compared to both of them... yes the fto has mivec and high revs but the vectra just sounded beefier at low revs... nice v6 burble :)

Try removing the sound proofing under the bonnet??

Tbh I think you just wasting your time chasing a sound instead of just getting a good working filter and pipe system, one that produces more power and not just a noise like the Corsa brigade.
The mg is never going to sound like an Alfa v6 no matter what I do lol!

Tbh I run a full Janspeed and Itg and it's plenty noisy in the cabin area.

Are you sure the noise you used to hear was not coming from the exhaust manifolds as the only decent throaty induction roar I ever heard came from car like westfields with open to air filters or v8's with hollies and pan filters.

Mind you the 458 I heard the other day sounded like a swarm of wasp's with a steroid problem!

not sure which part, if any, of the vectra vid was worth watching. I could pick up the noise now and then.



Induction Noise
easy enough to get, but usually at the expense of power.

the kv6 is fairly quiet until the balance valve opens - which gives iduction roar.
again, when the butterflys open you get another induction roar.

if this is the noise you like, you could wire your vis so they are open all the way through the rev band, it will sound nice but cost you more fuel and loose some performance.
an open air filter in the hot engine bay will help with more noise, but cost you some power.

fit the rover 800 manifold and have both vis open all the time, this and 2 open air filters in the hot engine bay will make a noise to die for, but like the above, cost you some torque.

or go down the bmw route, play some noise through the stereo. you could record some btcc cars thundering by and burn it to a cd, or alternatively try tuning into radio 1 which produces a noise that will create the same effect as listening to none stop btcc cars.

It's because of the vis system. It won't ever sound like a Alfa v6 without fitting a different intake system.

big open cone straight onto the throttle body sounds good but suffers heat soak in warmer weather.


sheeeeesh thats one of my old on board vids from the xpower day i organised in 2007....was a cracking day with great friends.
car had a bmc air filter with itg pipe to the throttle body and full exhaust system inc manifolds, i think its loud because car was stripped.

if im not mistaken the cat muffles some of the noise, if you put a decat pipe on it, it maybe a bit louder, i heard witnesses v6 at xcape mini meet thats how i knew where everyone was parked lol

Been here before. The Vectra does sound awesome tbh and you will not get that from the kv6 set up. BUT the kv6 has its own gorgeous and unique sound system. Just down to them being different cars with different set ups. When we had the L reg GSi Corsa it sounded like a scooby just by drilling some holes in the bottom of the oe airbox.

Agree with above. I got hand crafted enclosed unit with normal silicone and stainless pipework, de cat and stainless cat back exhaust and she sounds lovelly. I get many admiring comments. Had a guy behind me last year and we ended up at the same country pub. He even turned his music off to listen to her pulling uphill.

Lol, the red or black one?

v6bloke - that gsi vid was what made me decide I need and induction kit! Nice vid when you get your foot down.

Best intake sound I have had is from a BMC with no cold air feed on a itg-copy psh pipe. I must get a vid of mine vs Wit's car. One is bassy and muted, the other is out-and-out raw noise :)

Here we go: I'm Sure Aldon won't mind me linking them.

Grey, PIPER 4" + itg foam filter in the wing.

Out of them 3 vids the first one sounds the best... i think you seem to get what im on about... my old gsi sounded like a proper 'v6' when foot was plonked... the 180 doesnt really make the same sound at all... its very muted even with a catback and when i had a piperx bolted to the end of the rubber hosing coming out of the throttle body! its almost like the inlet mani stifles the v6 note... but going off them vids it looks like cone to inner wing does the trick... but im ******ed if i know how unless its because its nearer to the cameras microphone :S
