header/exhaust
first of all, thanx for the replie Rich. on a scale from 1-10 i'd say a 5. its not too loud.
anyway, right now im running without any cats, wich brings up the following questions:
1- it took three weeks for the check engine light to come on, why??
2- the 4-1 headers that SR sells have longer pipes before all joining, compared to mine which are relativly short, is it possible that i am empting out(back pressure)???
thanx guys

The ecu goes through certain short term and long term tests, so your light doesn't necessarily come on immediately after a change is made.
With a header, pipe, and exhaust... you will be losing some back pressure. However, the low end losses are probably not bad considering the mid and high gains you should be experiencing.
