LT Headers on a '90 L98
I have been reading that a Long Tube header set up is a good upgrade for the L 98. I live in NY and need an emissions friendly car and have a couple of questions.
- Can these be purchased with the air pump tube fittings included?
I know the O2 sensor ports are available
- What is the major difference/advantages between the ceramic
coated and powder coated pieces?
- On the '90, I have the pre-cats almost immediately after the stock
exhaust manifold. Can the headers be installed with the precats and
the main cats and still use an aftermarket "cat back" system? I
presently have a Magna Flow system
Based on these issues any recomendations (other TPIS $$$$$$)
Thanks

2. Ceramic is better, results in less heat in the engine bay=less damage to electrical and heat sensitive parts. Powder coating is just to look at.
3. No, longtubes delete the precats. So if they are part of your visual inspection, you will not pass. That does not mean you will fail a sniffer pipe test however.
