You must be using some special kind of fuel, since I've had issues with black soot on each of 5 cars that I've installed test pipes. Two of these were S2000's. My '02 had a test pipe with a totally stock exhaust, and it would actually blow a black cloud of soot if I did a long drive on the highway immediately followed by full throttle in 1st gear.

 

that's odd, I'm using Chevron's 91 octane gas. Even when I go to the track, I don't get the "soot black cloud."

 

The black cloud only happens when you gun it in 1st gear after LOTS of light throttle driving. I haven't noticed that to happen since I replaced my OEM mufflers with Magnaflows, so my theory is that the soot was collecting in the chambered mufflers, then getting blown out all at once the first time I gunned it in 1st.

Both of my S2000's have been light colored, so it is easy to see the soot when I do a "white glove test" on the rear bumper.

 

sorry this isnt guna help but i got a qeustion too...
I got edge headers, invidia single exhaust system. What kind of test pipe should i look into getting.

 

it depends, does is your exhuast 60/63mm or 70mm. Like it says in previous post, it doesn't matter what brand test pipe what matter is the size. So if your exhuast system is 60/63 mm from the cat then you'd want 60/63mm test pipe. If your exhuast system is 70mm from the cat then you'd want a 70mm test pipe.

 

Hey guys,

I had one more question regarding my setup.
(RSR gt2, Invidia 70mm Test-Pipe, and the PLM headers)

I was speaking with a couple of friends regarding this and a couple of them warned me about a rattle? I guess inside of the car you hear a lot of rattling? I'm not quite sure, anyone have any issues with "unique" sounds?

 

I realize this may come across as me trying to be "grammar police", but S2000's don't have headers. They have a header (just one).

 

as far as a rattle goes. if you bolt everything up correctly and tighten it down there should be no rattle. might be a little raspy. shouldnt rattle.

 

@Gernby
Dang it >_< ...Bad habit, my mistake.


Alright, thanks again.

 

If the exhaust winds up having much drone, then you'll probably have rattles inside the car from various sources (soft top tray, dash board, etc.).
