Noob with questions
there was a code, but it doesn't work any more. I asked for a new one, and he emailed it to me. but then i had issues and never ordered it. when i tried to use it, it said expired. I emailed him again, but never got a response...
Still no answer on the full exhaust vs slip on. Haven't been able to find any dyno results on this.
Sometimes motors can breath a little too much sacrificing low end torque. Smaller cc engines are a little more sensitive to too much flow.

Others on here confirm that they found it harder to loft the front end with header in place... but were happy enough with gains in other areas anyway. However.. if you do one of the big bore kits... there is significant gain to be had here on both sides, especially if you open the other end up with a pumper carb. You can see this on Dyno results at Bill Blue's sight (he supplies the 351 big bore kit.
FMF has a relatively new megabomb header which is 'supposed to save bottom end torque like a long header and still open up the revs. I'll let you know how it feels when I get it installed

as an aside, many upgrade the exhaust with the KLX 300 system, which I believe is a SMALL step up in header size and may be the happy medium that gives a real gain.
