Easy induction sound (unplugging a pipe?)

[Addicted]

Hi,
I saw on a thread (but now i can't find it for the life of me from searching), that some 182/172 users have disconnected one of the pipes on the intake (i think a breather) which apparently gives you alot of induction noise! I just wondered which it was and if anyone has any pics? But more to the point, if i did do it, is it safe? (Surely it's connected up for a reason? )
Thanks,
Matt

I thought it was achieved by removing the acoustic valve?

ahh yea that was it!
so ignoring the pipes part of the post, same still applies, what is it, how do i remove it, and is it safe?

edit: now i know what to search for, just ignore this post, as i imagine its been posted a million times

just one final question as i don't want to bring up old threads that don't need to be - if i just unplug the CAF pipe instead of removing the valve (wouldn't want to for warranty etc, and easier etc), this will have the same effect? i saw that perhaps you may lose a bit of power due to warm air, but apparently the stock CAF sucks anyway so it'd be about the same, just with more noise?

 

[hipwell]

I took off my valve and to be honest I still cant hear the induction sound over my exhaust and decat anyway. You can remove one of the pipes yes but it may affect the performance Of the car for the worse.

just tried it then & warmed up the car to test, much much beefier induction, and i have the stock exhaust with decat (can't mod til my warranty is over), very impressed; though like you said i probably lost a bit of performance but it's worth it i think!

 

[p@blo]

If you're just wanting more induction sound have you considered the R25 v6 airbox?

 

[Addicted]

i haven't, but didn't want to change parts because of warranty etc so will just keep it stock

Just remove the pipe going from the air box to the acoustic value if you want a bit of noise.

Is this the one going into the airbox from the right? If so, how is it attached? I can't feel anything connecting it but when pulling it away from the airbox it won't budge.

Also, do you pull the whole pipe out or leave it loose once you've disconnected it?

Is there any power loss from doing this? Or do you just get a bit of induction noise?

 

[Addicted]

just pull side to side should come off, and also i just left it half way between both ducts, so i still get cold air, but more noise!
perhaps slight loss of power, but up to you to decide!

 

[ScarySquirrel]

Cool, thanks for the quick reply. Sounds easy enough to do so I'll see if I notice a loss in power and decide which I would prefer.

 

[Addicted]

i went for noise, not much power loss (if any) i dont think

 

[ScarySquirrel]

Awesome. Does it make much difference to the noise then?

 

[Collister]

hmm has anyone got any pics of this? i aint looked at mine will have a peek tonight
does it give much more noise?

 

[Addicted]

made loads of difference on mine!

 

[ScarySquirrel]

I just yanked mine out and went for a quick drive. Certainly makes a nice sound now
It's definitely safe, yes?

One thing that concerned me though, there appeared to be some oil spillage around the entrance of the CAF and also at the entrance of the airbox. Is this normal?

 

[Addicted]

i didn't have any oil around mine!
pretty sure it's safe, it only stops a bit of cold air from the pipe (i kept mine in so it's in between the two airbox holees so i get cold air anyway, it just doesnt suck it as much!

take the acoustic value off. i done mine at the weekend sounds deeper wit panel filter. i removed the pipe and i taught it sounded like a 1.2 wit a filter on it. so that went back on

 

[Addicted]

i've got a K&N filter, acoustic valve still on but the pipe unplugged!
sounds beasty here

ah yea it sounds ok. but after a while youll get sick off it

 

[Alx]

Any pics?

 

[Addicted]

will take some later if it stops raining!

 

[Collister]

Any pics?

its the pipe behind the headlight u cant miss it
done mine last night what a difference it sounds tonnes better now

 

[Eddyg]

Yea i took my one out. You really can't miss it. Right hand side of the air box. You need to squeeze it a little bit as there are little clips so to speak keeping it in place. Performance wise i think it made bugger all difference. In terms of temp it is very similar there, JMS's rs2 feeds from the same space!

 

[ScarySquirrel]

A few days after doing this and I am really please I did. The sound is really nice in my opinion, and I haven't noticed anything different with the way the car drives, it just has a bit more grunt. Nothing over the top, just a bit of a growl when you get higher in the rev range

 

[Collister]

Ive changed mine back now got borred of it, and i get better mpg lol

Get a ph1 airbox and run it with no airfeeds. There are no heatsoak issues as JMS proved. Something like 5 degrees above ambient at 60mph.

It sounds epic. Best free mod I ever did to my 172.
