Speed Engineering headers are made out of 304 stainless steel and offer great quality, performance, and affordability. These headers are mandrel bent, tig welded, and feature natural stainless steel construction, and they have all been dyno proven. Speed Engineering stands behind their headers in saying you will not find a better fitting, quality built, budget header for your vehicle.

Other improved features over competitors include V-Band collector construction, merge spikes, port matched flanges, and improved header to block/chassis clearance.

Features include:

Mandrel Bent Tubing
Full 1 5/8" Primaries
2 1/2" Collector
V-Band Collector Construction
Collector Merge Spikes
Port Matched Flanges

Note: "For LS series engine swaps only" These do not work on standard SBC or BBC.

Note: If using a larger 4L80E or older Turbo 350/400 transmission the bellhousing ears may need to be trimmed for proper clearance. These headers are tucked in tight to fit into older, narrow frames.

Excellent online experience

I have ordered from AZ a few times and they are awesome! Definitely my first choice 🤘🏼

Perfect

Put on my 1990 Silverado LS swap looks great sounds great

Awesome

Excellent product

Out of the box these seem like very high quality. They have very thick flanges and the wall thickness of the tubing seems more than adequate. I installed the headers on an LS swapped c1500 and the only figment issues I had were that I had to re-route my hydraulic clutch line and I had to remove the drivers side tin heat shield. Factory straight boot plug wires will interfere with header tubes on 2-3 of the cylinders so wires with angled boots are a necessity. My only complaint about the headers is that I wish the v-bands were stepped to ensure a concentric fit. Not a huge deal but it would make fitting up the rest of the exhaust a little easier.

Didn’t fit 97 k1500

Was excited when product showed up. Looked great and nice welds. But when I put them on they ride real close to the block and it sent the left side right into the front driveshaft so I don’t think they will work on 4x4, but could’ve made work on 2wd. So was bummed that I had to return. So why am I giving a 5 star?? Well because when I called in to Pro, I was treated excellent. They didn’t hassle me and didn’t tell me I was doing something wrong with the install or it was my fault. Very very happy with the customer service. They took the return and paid for the shipping. For this reason alone I hope to buy more products from them on the next LS swap. A lot of aftermarket company’s can learn from this. Good customer service goes along way and will come back to you in the long run!!! Thanks Pro Performance!!!!!!!!
