Question for Stillen Exhaust owners
 
I didnt really notice it until recently, maybe I always have my music too loud, who knows. But right when I turn the car off, theres a consistent thud I hear, not a metallic thud either, and it sounds like its coming from right around the resonator area, i've never had this happen with any exhaust setup in my life. Now, one would think "hey, its just the metal cooling off after being heated", and thats what I initially thought. It never happened with the stock exhaust on my car once. You can actually hear the thud from inside the cabin, and its even more prevalent when you peek down underneath the car. To describe the sound, it sounds like someone is flicking the pipe with their finger around every 8-10 seconds or so. Not sure if this is normal or not, has anyone else had the same experience? I personally torqued each bolt as tight as possible, so i guarantee theres zero chance of it having a leak or loose bolt.

i am no expert, but like you said, i think its the heated metal cooling off.

I've just never heard an exhaust make such a loud thud from cooling, usually you hear little metallic "tink" sounds, glad im not the only one thats hearing it though!

In the summer time, it's very noticeable. No worries.

i'm curious if any of the other systems have this same problem

spearfish25 02-25-2010 06:26 PM

any metal exhaust will make this pinging sound on cool down

I never had that with the magnaflow I had on my G, or the Injen I had on my GSX, which is why it seemed new to me. I know exhausts will make a pinging sound when they cool, but this one thuds more than pings ya know?

Haven't really noticed any thuds. Video?
