Exhaust Turbo Headers 1-3/4 x 3 in. Up and Forward Facing for Chevrolet GM LS1 LS2 LS3 LS6 LS Based V8 Engines

Well made

Go big single turbo on any ls if you are just trying to pull times and dyno numbers. Look up the comparison and you will see.For those of you like me trying to cut spooling time and like to gas it in the corner then follow these tips.1. Buy titanium wrap for both the manifold and titanium socks for your plugs and wires. Heat shielding should be bought as you buy this!!! You will have to relocate your coils as it is because this gets extremely close to your valve covers.2. Elbows will be the only way you fit any size turbos in your truck engine bay without cutting out cross member. This seller along with many others sell elbows 3” v band to t3/4 and you need to do that to fit with how long these are.3. Don’t try to install these if you haven’t made room with aftermarket radiator and fan. If you are putting this on a gen3/4 truck with a clutch fan you won’t even be able to get the elbows on if you have the clutch fan and shroud still on.4. Get ready to weld on your wastegate flange before you wrap everything unless you can find internal wastegate turbos that are at least big enough to handle a 3L engine each. You have plenty of flat and round area where it comes together to weld one on, and while you are at it plan on doing your O2 bungs as wells. They do sell down pipes that vband on to the turbos 2 O2 bungs on them.5. Do all the other steps to the engine before even thinking you can put a turbo on. Is your fuel system going to provide enough to match the forced air you are planning to add? Swap your cam, rebuild your heads, and at minimum get properly sized injectors. Engines blow up from too much air in the ratio and a rich engine sounds cooler than a lean explosion. Is your transmission ready to handle the turbo or will you be destroying the 3-4 shift on that 4l60e? Are you going to be wasting the boost with a stock torque converter?

I wanted to give more stars but there were a few things I didn’t like about these turbo headers…1.) the passenger side collector is 2 inches farther forward towards the radiator than the drivers side header, making it in-proportionate which is kinda a big deal if you ask me. I used em anyways because I didn’t realize it until after I cut the flanges off and shortened them.2.) the v-band flanges were not stainless so I ended up using some other quality vbands that I welded on later.3.) the manifold flanges are oversized and did not line up with the header bolt holes so I had to reem them out to make all the bolts fit through. (Very dissapointed)Other than that, these headers sound good, they make good power and they look really good too! Also all the welds are good and the material of the headers themself weld nicely also.

I used as reverse turbo headers and they come with the connectors. For the money they are great.

Fit was bad. also missing v bands

V bands are welded on crooked. Seller charged a restocking fee for a defective product
