This is what I will be done to my car which I DD to and from work. I put on at least 100 miles a day and have to deal with some traffic on the way home.

If you are feeling adventurous get the phantom electric supercharger

What's the BPB? Google it but nothing.

Billet power blocks. Thy are spacers that attach to the intake manifold to help eliminate turbulence which boost power. Performance gain is pretty ok for the price

Cosworth or crawford for those? With those how much should I be seeing. As for the exhaust, I have done a ton of research on the cats. Can I delete the front cat and keep the second, while still passing emissions, I'm in NH so I have to do them annually.
Thanks all!

Crawford. For the cats, it depends on the state. Do they do a visual inspection? Just a sniff test? Just an OBDII read? What are the state's laws?

This is what I found "In addition to a physical safety inspection required for all vehicles, vehicles with a model year 1996 or newer must have an On-Board Diagnostics (OBD) test as part of the inspection process. On-Board Diagnostics is a computer-based system built into all 1996 and newer light-duty passenger vehicles to monitor the performance of some of the engine's major components, including emission control components. The OBD system helps the motorist know if their vehicle has a defect that could cause excess pollution. In addition, it helps mechanics accurately diagnose problems and make effective vehicle repairs."

Thanks for the help here!

If that's all it says about emissions, then any tune can turn off that flag in the ecu and you could run catless. If you still have a sniff test, keep one of the cats. If you're not getting a tune, get a catted header so the o2 sensors will read correctly and get a catless front pipe.

Keep in mind I've never lived in NH, so I'm basing that purely off the one paragraph. So take it with a grain of salt.

I would not run completely catless because a "sniff test" done by any human who knows what a catless car smells like can detect you're catless, but maybe that's just me.
