Hey guys,
As you know I added the megan y pipe not too long after the test pipes... and now when I drive around, upon acceleration theres a sound coming from the Y pipe as if there is a screw loose. I checked underneath for a deeper look and what do you know I didn't find anything wrong. Also, I tried setting up the non-foulers on the 02 sensor to not turn the SES light on but was not able to fit as there is a very tight clearance to tighten up the 02 sensor. After a try of doing that I just reconnected the sensor as it was without the nonfoulers and had no SES light for about 70 miles. During the time the light was off I would sill feel hesitation when I would accelerate. I know this is due to the y pipe and would like to know if you guys have this setup? and if there anything I can do to fix this. The rattling noise was not present when the weather was warmer now that it's colder here this issue started right up very conveniently. I've tried to search for a similar issue but haven't had much luck.

 

Did you reset the ecu after install?

 

I had the dealer install it and more then likely they did not reset it... Do you reset the ecu with the rev up process?...
thanks for your response BTW

 

when i had an aftermarket exhaust, one of the pipes tapped against the other and created that loose screw sound also. make sure all ur bolts are tight. about the hesitation it might be an exhaust leak due to a loose bolt. but def double check all the connections.

 

I got the same set up. Mine would rattle horribly but found out the non-foulers were loosening up. Dont really notice any hesitation tho.
