I recently installed the f-sport exhaust last week. Been driving around and havent really noticed anything until my friend pointed it out when I was showing him the exhaust. He noticed the right side(passenger side) was more dirty. And when I revved it, more air was coming out of that side of the exhaust than the left (driver's side). Is this normal?

 

Normal. There's an explanation why, but I couldn't give it to you.

 

yea its normal. right side will always be dirtier with this exhaust.

 

One side is hollow. Go knock on the cans and you'll hear which one.

 

Yeah its normal, i experience the same thing

 

Same here ^_^ I have to clean the tip every other day =/

 

lol i posted the same exact thread a couple months ago. congrats on the new exhaust, get the intake to make your car really growl.

 

It is really odd that they did manufacturer the cans that way...but I'm sure there was a reason.

 

The left side is actually the muffler, the right side is a fake muffler with a straight pipe going through a can. By design, more exhaust flows through the unrestricted side therefore, more air & more dirt.

 

Yea mine does the same, whtevz

 

thanks for the responses everyone, thought it was weird but i guess its normal.

 

Same here, Left side is almost clean, while the right side is dirty as hell.
Just got it installed recently.
A lot quieter than I expected haha

 

My f-sport did that too. Right side is very dirty compare to left side.

 

I noticed that, and really want to know whats the reason though

 

i believe the right side is not a "true" exhaust.
