I'm a 19 year old idiot.
No ... really, I am!
But I too have noticed the influx of idiots.... especially in the powertrain forums.
What exhaust is the best?
Which exhaust will make me sound like a honda?
Which exhaust has the biggest tip opening?
I want a bigger exhaust!
Now... I don't have problems with asking questions about what muffler to buy (I even started a thread myself a few months ago, before buying gtguy's stromung... which is excellent, btw) but these people need to learn to do searches.
First thing I do whenever I go to a new board (or even this one) is to do a search for keywords related to my query.
Oh, and the USMB (where I'm a moderator) is a great place for technical advise. There are some guys in the 80's forum who have insane collections of older scoobies and rebuild them every other week.
The newer gen has a bit less technical knowledge, but you are still very likely to get your question answered.
