Hopefully a simple question with a simple answer. I recently installed a CAI, Magnaflow catback and CA header and now there is a buzzing type noise in the passenger compartment when I give it heavy throttle. I know it is hard to diagnose a noise without hearing it but I was hoping someone might have some clue as to what could make a buzz. Any help would be great

 

it's probably one of the heat sheilds... you just added a LOT of vibration to the underside of the car.... with the car running, get underneath, and if you can't find it like that have someone step on the throttle... remember that pipes will be hot, so this is best to do it when the car is cool... when i put my downpipe on, i had lots of vibrations because the heatsheild was touching the bigger pipe... i got a screwdriver, gave it a good push out of the way and that ended it...

you can also feel aroudn the pipes (again when the car is cool) to see if anything is touching, that's what i would do first.

welcome to the site, and i hope you find this helpful!

also, your new parts will sound a little weird until they break in fully after a few hundred miles...

 

my entire car vibrates with my setup. Its just one of the quirks that comes with having an exhaust.

 

hahaha yah ive got a whole custom exhaust setup and my car vibrates when i give it a lil gas..you gotta live with your new power..lol

 

Yea, I will do a check to see if anything is rubbing. Im just sad cause now when I go WOT I lose exhaust noise and gain a loud buzz

 

i just got exauhst on mine and the first thing i had to do is play with my heat shield cause it was causing a whining noise around 4-5K RPM's so that could be an idea to check on.
