Hooker Y pipe and o2 sensor ?
you will need either the bosch 13111 rear o2 sensors for your LT's now or you will need to get some o2 extensions for your front sensors.
I believe marylandspeed has the best price on that ypipe but I would personally go with a custom made ypipe from a muffler shop.
the 02 sims i believe the only way to get them now is used from someone so your best bet for that will be the for sale section.
thanks man the suspension is koni rear shocks, fronts i have kyb agx, strano springs, umi lca,lca relocation brackets and umi adj. panhar bar
