I notice that the right exhaust tip of my F-sport exhaust gets dirtier quicker (very noticeable, completely black on the right vs lightly smoked staining on the left) and it seems as though only water leaks from the right during a cold start. It also makes this weird bubble noise only heard from the right tip during start up and goes away after driving. Is this normal guys? I installed it myself did I miss something?

 

I had this same talk with someone yesterday. My buddy said the same thing happens to his F Sport but thinks that one side of the exhaust is only for looks. Not a true dual exhaust because it y's off.

 

^^^Oh that blows...You guys with HKS, greddy, JoeZ, and etc, do you guys have the same issue?

 

Hmm... remove the exhausts and pour water down the left side of the exhaust. If it comes out the other end, then it works... - j/k

@ Sffd103 - I believe a true dual-exhaust would require 2 separate cats / headers. Each exhausts need to connect up to the cat without splitting off at the Y.

 

knock on the right side muffler... its hallow i think its the right side lol either way only one side i hallow...

 

LoL, same problem as mine, and I had mine installed at the dealership.
I guess that's just how it works. >_<

 

^^^aight cool as long as I'm not the only one.

 

is the same with mine too. I guess shawdowman is correct about "true dual-exhaust would require 2 separate cats / headers. Each exhausts need to connect up to the cat without splitting off at the Y." oh well.. it still sounds awesome!! =)
