What is better long tube vs shorty headers?
For shorty headers, the port pipes actually merge into a single exhaust pipe in a much shorter distance. For long tube headers, the exhaust pipes are much longer and merge farther out. Because of this, each design impacts back pressure in the exhaust system in a different way.
Are headers worth the money?
The answer is yes, headers will boost performance – IF your vehicle is “prepared” for them. Headers take the place of your exhaust manifolds, which are the first part of your exhaust system between the cylinder heads and the front exhaust pipes. …

Are long tube headers legal in Massachusetts?
As long as the headers retain any emissions connections and don’t relocate the cats they are perfectly legal.
Can you run a engine without headers?
The problem with running without a header is that when the exhaust valve closes, it pulls in a little bit of outside air. The outside air is much colder than the hot exhaust gases flowing over the valves. The constant heating and cooling fatigues the exhaust valves and they crack.
Can you pass inspection with long tube headers?
long tube headers fail the visual test. the do pass smog though on the emissions test so its usually ok.

They use the OBD-II self test to determine if the vehicle’s emissions system is up to snuff. In that case, as long as the car does’t report any problems, the vehicle will “pass”. Most people tune out the post-cat O2 sensors and associated codes when they install headers, so the car will appear to be fine.
