Exhaust Sound

[Dan34]

Right heres my problem when i bought my gti 8v it sounded like a tractor really bad ticker sound on idle, which i thought was a front silencer blowing. Wasent a problem as i was gonna put a new full system on anyway. But now i have the system on and my car still sounds like a tractor, has a bad ticker/blowing sound coming from the front end of the car, the sound is worse from cold. I think this could be causing my car to have a lumpy idle

but my question is, it is the manifold blowing or something else?

i have used the search function but doesnt really give me the right answer

Thanks

Could be the manifold and/or the downpipe from it by the sounds of it. I take it you replaced the exhaust from the downpipe back?

Cant remember if the 8v has a 1 piece manifold to centre section, I know the 16v doesnt but its been a while since I put and exhaust on an 8v

i changed my down pipe and have a tinny blowing type noise and it seems to be around where the pipe goes from 2to1 and i have had mine on a ramp and checked it
only thing i can think of is to heat wrap it to try and reduce the noise
but check for blowing just to make sure

are you sure its not a mechanical problem and not just an exhaust leak?

Like above. Cover the exhaust tip and listen out for a 'hiss'

You may have an air leak. Check the rocker cover bung that seals the air breather to the rocker cover.

could also be a broken manifold stud. Had this before

could be the timing is out, i tuned up a digi gti the other week that sounded like that, guy had changed his zaust since he thought it was blowing.  turned out the cam was out a tooth and the ign was out a country mile...

Mine sounds pretty 'throaty'.  No leaks, I'm wondering if a baffle's gone.



Any other symtpoms of bad timing RJ?  Idle and power are excellent at the mo.
