If you get a low pressure catalyctic converter, its supposed to free up air and increase horsepower, right? Where can I get one? Its actually for my GF's 240sx.

 

You can get one from <A HREF="http://www.randomtechnology.com">Random Technology</A> and I think that there was another one but I forgot what the name was (Carsound or something). The other one might be cheaper but the RT has everything you need (hole for O2 sensors already drilled in, flanges, etc.)

 

Yeah, that's what I meant to say. Thanks
