Trust me, you put a Ravin and a Flow 40 beside each other and the Ravin will be a LOT more growly and low.

I don't know about you, but if I has carbon throughout my exhaust system, I wouldn't deem that a good thing.

that means not everything is burning right, right?
carbon is a byproduct of... oil?

i've also got a really fast kinda quiet ticking or something... is this normal, does it have something to do with the vortech? i figured it was a little exhaust leak?(which i know if that is the case, i need to get it fixed before it gets bigger)

sorry boys, i know i'm ignorant , but that's why i'm here

Carbon is a by product of too rich of a fuel mixture.

The ticking could be anywhere in the exhaust system.

Best bet is to take a lot underneath when you first start it up when it is cold and look for the puffs of condensation coming out of the particular area that is leaking.

Put on a new exhaust system, and after a month or so it won't be perfectly clean steel anymore. Carbon builds up on it, and the sound becomes deeper and louder.

Trust me, I've put on more than enough exhaust systems to figure this out.

yes, the Raven might sound better to you, but that does not make the Flow. sound raspy!!

Carbon will build up on any vehicle over a period of time. This will happen to all vehicle. Happened to stock vehicles I have, happened with the 454 I just built and put in, happened with the crate 502 that I just put in my car.....happens to any vehicle!!!!!

You might want to check your cap and rotor. Mine clicks when I first start my car up. Sometimes the clicking doesn't go away. I plan on replacing mine ASAP.

so the inside of your exhaust is just as pretty and shiny as when it was new...??

also... so carbon is a byproduct of oil then, since too rich a mixture means too much oil, right?

No but it is not covered with a layer carbon at all.

Carbon is the sign of a rich FUEL mixture caused by a engine that needs a tuneup or the timing is retarded.

i don't get what a rich fuel mixture is... does that mean that there's too much fuel compared to air?

Yes, the perect air to fuel ratio is 14.7:1

When you are running rich or the air filter is clogged you will run 11:1 or so and run with to much fuel and not enough air to properly burn it.
