I just got some body work done to my CL. Got into a minor accident, the work looks great. But when I got it back I noticed my car sounds different.
The CAI sounds like it vibrates a little when I start to accelerate. Instead of sounding nice like it used to, its sounds a little deeper and louder with some vibration. Its hard to describe but I know it doesn't sound the same.

Could the body shop have done something to screw it up? They were working on the rear bumper!

I also have the old OBX headers, and they've almost completely chipped away. How can I tell if they have a crack?

Any other ideas? I guess I'll check out the cai and tighten everything up first. If that doesn't make a difference I am not sure what I can do.

 

The only thing I can think of is if they were working on the rear they had to unbolt the exhaust and maybe they didn't tighten the b-pipe to cat bolts all the way? Or the cat to header a-pipe?

 

so i just went under the car and its def not the cai.
it sounds like its coming from right in front of the cat where there is a flexible pipe that eventually leads to the headers. im not sure what its called...

should i try to tighten the bolts securing that pipe?
i have extended warranty, should i just bring it in to paa? how much is the deductible for the acura care extended warranty?

any suggestions?

 

Does it sound like some rattling in the front but it goes away after you reach higher speeds?

 

yeah it does go away when i reach higher speeds but im not sure if I am just drowning it out. its hard to hear with the windows closed. its a very deep sounding vibration. You can hear the air flowing and causing the rattle. I went under the car while it was on and I'm pretty sure the area i described is where its coming from

 

ok so def think that flex pipe is leaking. so how can i be sure.
I've heard of a couple of methods:
Incense smoke
Paper clip on string
Laser Pointer
Any others?
