Ok i am thinking about getting headers for my 99 formula. I am 99% set on getting Coated LT pacesetters i just dont know if i want ones with the emission stuff or not. I live in Florida so there isnt any emissions, but i was wondering if the car will still run right with out cats.

Is there an installation guide for installing headers on the LS1? I am confused on what parts i need. Could some on make me a list of eveything i will need to install LT headers?

I have installed headers on carbed cars but never a car with a computer so i was wondering what i have to do diffent.

it'll run ok. might smell a little funny. just get some o2 simulators

 

02 extenders and new gm gaskets or some people re use the old ones .. a few 10 mm wrenches .. also a good idea to throw in some ngk plugs ....all the header bolts are accessable from up top except the back one on the pass side u can get that one from underneath .... same goes for that spark plug ..... headers go in from the bottom ... just make sure and jack up the car high enough .. pacesetters should slide right in =)... make sure and fire it up with just open headers... sounds pretty cool

 

with no cats you wont need the o2 extensions
