Ok really want to get this but i have a couple of questions bout it.
1) How does it effect emissions
2) Do i need to get other exhaust work done
3) Does gas milage go down?
4) Is low end power lowered?

Yea i know i sound like a newbe but help a brother out please!!

 

1) Removal of precats will cause you to fail emissions testing if you don't warm the car up prior to testing.
2) No
3) Yes and no. Mine went down initially because I kept flooring the gas
4) No

Another point about emissions: Removal of the pre-cats in the OEM Y-pipe is a violation of federal law and renders your vehicle technically un-roadworthy in every state.

However, if your state just does a tail pipe sniffer test and not a full visual inspection, you'll probably get away with it.
