OF COURSE I SEARCHED!!!

with that said, i made a thread about this a while ago but havent gotten around to solving the problem yet. i installed a ws on my gf 05 EP3 and a <FONT COLOR=""Red"">rumbling noise </FONT>is herd from under the car around the e-brake area

at first i thought i left something loose or that it was hitting against the sway bar .

but..

i went under the car and checked and the piping seems to be rubbing against the bottom of the car itself (not heatshield). right after the cat where the midpipe first bends. there is no gap in between the car and the piping as if the piping was too big, which is not (2.25). i was thinking about maybe bending the braket on the header/cat which is the only one i see would help lower the midpipe down a little? .

DOES ANYONE ELSE HAVE THIS PROBLEM? or any suggestions?

ive herd of this happening with ws1 on ek coupes..


thanks in advanced

 

I don't have that exhaust (I've got a Fujitsubo RM-01A instead), but I'd try tweaking the hanger at the cat-midpipe junction as well.

I recently gained access to our underground garage at work, and my midpipe was always scraping at the entrance. I put the car up, stuck a screwdriver into the hollow hanger tubes back by the resonator, and bent them a little bit downwards so that they lifted the midpipe higher. The next morning, I cleared the garage entrance with no scraping.

Anyway, that's my example of adjusting the exhaust hanger to change the pipe location (even though it was the other way around)...

 

yeah the thing is that the apexi hangers arent hollow i bent them today with a hammer a little but it didnt do anything

 

Same thing happend on my car too. Same year, Same exhaust.
I red-neck engineered it. (I am from Missouri) I used a die grinder and a dead blow hammer to flatten out the raised portion of the floorpan. I tried to moving the hangers to no avail.

good luck

hmm thanks. yeh i was thinking of getting the exhaust piping flattened a little not the bottom of the car , that im scared to do bc it would probable be a lot more expensive to repair than the exhaust

 

yeah my exhaust does the same thing but i have a greddy sp2... but it only happens with it rains for some reason...

 

ive heard about that happening when it rains . i think my case is different because at all times there is no gap between the pipe and the bottom of the car.

 

well i drove in the car again today . ive seen to have fix most of the problem by bending the brackets towards the rear of the midpipe. but now you only hear it when the car is idling, first turned on, or when turning off. im taking it to a muffler shop tomw to see what they can do
