LS Exhaust Manifold Header Flanges for GM Truck LS manifolds 4.8L, 5.3L, 6.0L
# GF – LSTEF (SET) Exhaust Flange Set
If you’re building a Turbo-Charged LS motor, then you can’t beat the price & reliability of the OEM Chevrolet/ GM
LS truck manifolds. They are excellent performers, and can be found in nearly any salvage yard for a great price !
However; the flanges on them are very unique and are nearly impossible to find. This auction is for a pair of flanges,
(Drivers side & Passenger Side)that you will need to build your exhaust system for your LS motor. We have built these
flanges out of the highest quality materials and guarantee a perfect fit !
This is a set of LS engine exhaust manifold flanges for the LS truck manifolds. These are made out of
A36 Steel with a 2.5″ hole to match the manifold outlet size and designed around a 1999 5.3L exhaust
manifold, but are the same flanges used on all 4.8L, 5.3L, 6.0L trucks and SUV’s from 1999-2014. Alot
of people are using these flanges to make their own turbo set ups simpler, using the mainfolds
from trucks, instead of making headers.
Whether you’re new to Turbo systems or a seasoned veteran you most likely know that Flow is the name of the game,
when it comes to exhaust systems. That’s why we chose a 2.5″ in. Dia. hole for these flanges. The manifold outlet is
very close to this size so you won’t be restricting the exhaust flow when you build your pipes.
