K-Tec Exhaust rattle

[fUbAr]

Ive got a K-tec system on my 172, and when idling it rattles.... almost as if theres something loose inside rattling around.

it only does it at idle.

any ideas?

 

[fUbAr]

bump.

u got a de cat dan?

 

[fUbAr]

nope, standard cat

..is it rattling against the mounting? i had this prob had to wedge a piece of rubber in there and cable tie it..sh*te. fixed with a pro-speed tho

 

[Clarkie172]

mmm, u had it on a ramp? best bet is to get under it mate and listen to it! i sorted mine out, it was near the cat catching on heat shield

 

[fUbAr]

its an irregular sound... sounds like its coming from inside the exhaust somewhere. I thought maybe it could be the cat breaking up?

 

[Clarkie172]

could be the baffles on their way out?

 

[fUbAr]

the what? lol

i live 4 miles from K-tec, so might pop it over there for them to look at.

mine was rattling mate, got a new rear bracket from renault which holds exhaust £19 and problem was solved!

i fitted a new bracket last month.

it sounds like its coming from inside the zaust... not outside if that makes sense.
when i rev it slightly it stops rattling.

Thats probably becuase the vibration is bigger at lower revs (i.e the amplitude is bigger).

If its a kind of loose rattling it could be just hitting something as it vibrates wider at lower revs.

Thats the case with the exhaust I have on my car (its a mk1 clio though) as its only noticable at idle or very low revs.
