hey guys just a qiuck question got a new full system 2.5", hiflow cat and 4-1 headers......
its been a week now and a big ratteling noies is coming from da cat what caould it be??? cant get rid of the noies........
its bad pealses help...
thankz bobby
i hate noises... check the screw.??
nah its welded on to the headers
did you check the header hanger isnt touching ? ( located under the oil filter /collector area - its where teh stock header joins to with 2 x nuts)
IF this is left on , it can touch the collector and make noise. Easy to take off
does it sound like rice shaken inside a tin can?
probably little bits of the welds broken off and are just rattling around in your exhaust
good luck getting it out though
your new exhaust mite be hitting the heat shields underneath becos of the bigger diameter exhaust ?
do u have a flex pipe welded onto your cat - headers
if not expect it to crack in the future
best to of have kept the donut flange
i do have a flexi pipe join and i jucked the car up to see if the new bigger exhaust is touching enywhere nogo there ither. its comming form the cat area but still dont know what it exactly is.........
thanks fror the help
the noise is very bad now its sounds like my car is gonna fall apart....
now i relies that it may be little bits of broken weld......
dont want to drive it its dat bad should i take it back the the exhaust shop??
definately have them take a look again, they'll probably try to blame your cat dying at first(unless its a metal one)
when i had mine cut apart i tilted the pipe and all the metal bits came out and the cat was fine
I hope the exhaust shop is close to where the car is. Just get it in there as soon as u can and make sure they fix the problem b4 u drive off again! Just make sure that they dont try to blame it on u. You paid to get it done properly and u deserve to get something that works. Just make them feel bad about it and tell them that u paid good money and u expect it to be fine. Hopefully they'll fix it for u for free. Have u still got the receipt?
i would guess it would be something rubbing against your heat shield.
just jack up car, and tap out the heat shielding a little
sometimes the pipe hits the gear shifter as well,
do you get the rattle in all gears
