Long Tube Headers

For what its worth, I think the bassani "optimum length headers" are a good idea. They are supposed to be much better than shorties and they don't have the ground clearance issues associated with long tubes on a lowered car. I also read they are the easiest to install and they are ceramic coated. Just food for thought.
 
I love my SLP LT's also.. and if you were interested.. you could run catless all the time and when it came time for the e test you could take out the SLP race pipes (if you get the SLP mid-pipe) and put in cats instead ;)
