I'm his friend, and I have the hotshot header. Marc was close in his explanation, but here's the details.NISMOMarc said:Don't go knocking Hot Shot, my friend has one on his SpecV and it's a great mod. Great sound, respectable power, and looks good. And unfortuantly it's not smog legal it elimanates the cats. He did get a custom pipe made from Stromung so that the SAS light would not come on. The only problem he had with the header was that one of the bolts didn't line up perfectly.
And I'm looking for any options other than $tealin. He's a rip off and a bullshit artist. Somebody voulnteer their car. I wish I was out on the West Coast so I could.
The Pre-cats are there just to help out with cold start emissions.I think that if you are worried about smog issues, then you don't want a header, because to make a good enought gain the pre-cats would have to be removed. Go another route for power. I want no cats, and I don't care about smog.
