I have a 99 SS and was wondering what HP gains the SLP headers would give me compared to the factory ones. also wondering since the SS has the SLP options done to it would putting SLP Headers on it be considered origional or would it make the value go down? Also wondering how hard would headers be to put on an LS1? Thanks!!!!

 

your car doesnt have headers from the factory,those are exhaust manifolds.you will get about 25 hp to the wheels with long tubes

 

OO i was always told they were "factory headers" but there obviously wrong. Do you or anyone know if the car would still be considered original with the SLP headers or would it make the value go down?

 

wat is your purpose with the car? lik do you want to keep it all original or you want to do aftermarket stuff? the slp headers would change the car they wouldnt be original but idk how much the value would change. if your worried about value for selling at some point then keep all the stock stuff that you remove or replace
