noticed there's more black soot in other g35 sedans tailpipe when compared to mine........i know my bolt-ons obviously have something to do with that, so my question is, am I running more effeciently because there's less black soot on taipipe? or even a little lean? hope i'm making sense to someone......

 

Intake and plenum spacer may make you run slightly lean.

 

Me + Bone Stock = No Soot A'Tall

 

No soot on mine either (stock), guess that blows the bolt-on theory.

 

Shows that the ride isn't 'grannied' at all, as well as not run for short distances.

"Shows that the ride isn't 'grannied' at all".............humm, sounds about right!

forgot to note i have 28,xxx miles on my January purchased 04. I drove car like anyother day during break-in period....didn't redline but didn't baby it either........

 

I abuse my car so much that I leave a TRAIL of soot wherever I go, it just pours out of there.

 

make sure there're no parts of valve springs and such in your soot trail.....if so promptly go to dealer............

 

The pistons won't fit thru the exhaust pipe, so I know I have all of those left at least

 

I flogged the $hit out of my old Maxima and didn't have soot on the tail pipe. How does that fit with the granny theory?

 

Soot is a byproduct of combustion, it's normal. Some cars produce more. Excessive soot (sprayed all over the back bumper) is obviously the result of running way too rich.

I wouldn't be too concerned. Bolt-ons alone don't really screw up the AF ratio that much.

 

that's the reply i was waiting for, makes much sense........thanks.

 

Hey guys,
I have a '04 G35 coupe.
I recently noticed that the left tailpipe is a bit lower than the right one.
Any ideas how to align it with the right tailpipe??

Appreciate your help!!!
