Whistle above 5.5k

[AndyWilde]

Hi all,

Since changing my k tec stealth back to standard I've noticed a whistling noise when caning it above 5.5k. My other ph2 did it as well.

Is it something I need to get sorted or just a characteristic of the exhaust??

Thanks,

Andy

My KTR exhaust has a raspy whistle above 5.5k

With the Ktec i didn't hear ne whistle thow which is strange but with the STD system bk on it's there :-$

 

[Aluco]

My ph1 std exhaust never whistled

they whistle when they are about to fall off or mine did anyway lol

Let the engine tick over and get down so you can look at the join where the cat is and rev it. Probs coming from there. My 182 does it but I'm sure they all do.

So I guess I need to get it looked at??

You probably have a leak, check the CAT links. Though this is more common to the 182 but it is said it can cost power

Mine does this. Its caused when exhaust gas leaks out at high engine speed. Think mines coming from a crack rather than a leak :-/

I used to have this. It was the cat to manifold gasket.

I used to have this. It was the cat to manifold gasket.

This. About £40 part for the fixing kit. Birchdown sorted mine. It still whistles very slightly on full chat, Andy suggested it was standard, its certainly not blowing anymore as its clean at the joint.

I've got this!
except mine's a 1.2...
Thought nothing of it tbh.

 

[AndyWilde]

Thanks guys I'm goin to get it looked at tue can somebody post a link to the part I need?? It does feel down on power ATM so thAt would explain things !!

 

[AndyWilde]

Been looking at some other threads and some people say it's a characteristic of the std exhaust?

 

[OiNK]

Yeah, mine does a little whistle too, I though it was normal of the standard exhaust to be honest...

 

[kristian]

my 182s always done it... and its had a new manifold too cat gasket. think its normal?

 

[AndyWilde]

Turns out the STD cat back I had has got some holes in it. Looking to get it welded up - has anybody got any experience of welding exhausts i.e. is it worth it???

 

[DMS]

Better to get a new stainless one IMO. If it's started rusting, welding it up won't help all that much. It'll just rust somewhere else and you'll be back to square one.

 

[fuel_slut]

Difficult to patch up with a welder as exhaust wall skin is very thin.

As above, its better to just replace with a stainless item.

 

[AndyWilde]

Thing is I want to do it as cheap as possible. Where is the cheapest place for a STD back box??

 

[fuel_slut]

Cheapest place would be a second hand one.

A new one will cost almost the same as a stainless sports item.

:-( I am now wary of 2nd hand ones as the one I bought has holes in!
