just some general questions:

with rotors, what's the difference between slotted and drilled?

and with headers what's the difference between ceramic, stainless steel, and 1 piece, 2 pieces, and 4-1, and 4-2-1??? i know what it means physically but performance wise, what's the difference?

 

Here is the answer to your rotor question.

haha thanks, i just found that link in another thread. appreciate it = )

 

4-2-1 = Mid range

4-1 = High rpm

 

ceramic runs cooler as well.

 

so then generally for a daily commuter you'd wanna go with a ceramic 4-2-1??? or is that all a matter of opinion???

i drive a 98 ex coupe, it's automatic, but if i were to do a full cat-back, what would be the best to do now that i would be able to carry over when i do a tranny swap???
