i got a quick question about my downpipe.
it sounds like ive got a leak while im driving and i cant tell where from. i put RTV all over the flange for extra sealing but i dont know if that worked or not..
i only get the noise at about half throttle. think it could be from not getting the o2 sensor tight enough??

 

have someone drive while you ride under it on a creeper. that way you get real results

 

u would be my first candidate for that.

 

if you dont have any solid mounts u probably cracked ur flex pipe. its very common mine went about 30K. if its the factory dp. its covered under a 80k mile cat warrenty. with the engines moving around so much with rubber mounts the "flex" pipe cracks.. the rtv wont hold because there is too much pressure. either take it to the stealership or buy a aftermarket one..

 

it is an aftermarket one... sorry i didnt add that. and i do have the solid mounts.

ill figure it out. if all else fails ill weld the bitch.

 

lol yeah just weld it..problem solved

 

I had the same problem,pulled the dp and i had a blown gasket from the header to dp.

 

i have the same problem.. my dp flange and catback flange dont meet very well... i have a gasket and rtv and it lasted about a month before it started leaking again... i dont wanna weld it but im probably going to do it anyways because its an annoying sound
