Mike T, need Lightning help...
Hello Mike, fairly new member here and have heard nothing but great things about you and your company. I will be ordering a programmer for my '05 screw from you shortly. My question in on my other toy, an '02 Lightning, stock except for full bassani cats and cat-back. With this system on now the exhaust tips seem to run very black and sooty looking, dont remember this before. The truck runs great by the way. Any ideas if this is a problem or not? Thanks for any input....Jeff

Hi Jeff,
My kinda guy - a nice new decked-out F-150 SuperCrew, *and* a Lightning - I like the sound of that driveway inventory.
Today's vehicles do tend to accumulate more black deposits in the tailpipes than did typical carburetor engines years back - yours sounds like it might be a bit much, but I'd really have to see it to tell for sure. That can happen with some other aftermarket cats, where they'll accumulate significantly more soot in the tailpipe tips than they did with the factory cats. The only aftermarket cats we'll use are the Magnaflow units, as they do clean up the exhaust properly and always satisfy the downstream O2's, etc.
Most likely you're going to have to deal with this as long as you have the Bassani cats on there - even with the Magnaflow cats, we do see a slight increase in sooty deposits in the tips over stock, but not a lot - I run the Magnaflow cats along with long-tube headers, X-pipe, etc., on my Lightning, and while the tips get a little bit more sooty than stock, it's not really significant, and it passes sniff test for emissions - something we insist on.
Assuming nothing else is pushing the A/F's rich and that those present cats are functioning correctly, one thing you could do would be to put on another set of cats - run 2 sets just like the factory does. Throw on a set of Magnaflow's in addition to the Bassani units, and you will see a reduction in those deposits, without sacrificing power.
It's a thought...............

Hello Mike, thank you very much for the reply and compliments. I definitely do like my F150 toys! 
I guess the sooty pipes are nothing to worry about, I don't get any black smoke on acceleration and the truck does run awesome. I would imagine its better to be a little rich with a blower than to lean! 
Take care and save me an Excalibrator.
