Our Summit Performance® headers are manufactured from mandrel-bent tubing for superior flow and greater horsepower. The headers feature a pressure-formed collector for a better flow rate and a jig-welded tube-to-flange plate for a perfect fit. They're made for off-road and racing use only. Unless otherwise noted, these headers are designed to fit the vehicle as it came from the manufacturer. This includes components like cylinder heads, chassis, steering, motor mounts, body mounts and bushings, etc. If your vehicle is using aftermarket components, parts from other applications, or custom-altered parts, then it is the installer's responsibility to verify fitment.

Special warning regarding Summit Racing® painted headers only. The paint on these headers is not designed as a final finish; it is designed to protect the headers after the manufacturing process and during shipping. This paint will not withstand the high heat associated with engine break-in, nor will it withstand the heat cycles associated with any type of driving. It is recommended that this protective coating be stripped, and a high heat paint or coating designed for use on headers be applied.

Q:

what is the overall quality of this product? Does it require re-torqueing, and do the flanges leak?

Asked by RANDY on October 03, 2017

A:

Good quality and price. Checked all the bolts after a week and none were loose. I really had some concerns about leakage around the header gaskets, but no problems have occurred. I have some similar summit headers on another vehicle for about a decade.

Almost perfect

Summit RacingSummit Racing Verified Purchase

SUM-G9006-9
This is my first set of ceramic headers - I wanted to spend a little more money and have something that lasts. I only gave this set 4 stars because of a few small issues; someone ponying up the money for these over a cheap steel set does have some expectations, after all. The finish is nice but had a few shipping marks. 4 on Appearance. As far as quality is concerned, I checked the flanges against a straightedge and they were about 1/16" to 1/8" off. That being said, they sealed up just fine using the included gaskets. The truck had a rusty old set of Mr. Gasket steel headers, and when I compared the tubing bends I was pleasantly surprised to see more quality work done. It actually made the installation easier. My only qualm is that they don't give you washers for the header bolts, meaning you are gouging the ceramic coating when you torque the bolts. Maybe you can't use washers on headers; I don't know. 4 on Quality/5 on Ease of Install. Overall, they look good, sealed properly, didn't discolor after a few test miles, and sound great for an entry-level set of ceramics. I'd definitely buy them again. 5 on Price/Value. ...read more

Perfect fit! Absolutely no issues that couldn't be easily overcome. One tube could be a bit longer fron the exhaust port so you can get a socket on the holt and one plug requires a wrench to get at it, but nothing that's a deal breaker. Best fitting headers I've ever come across and the pricing for ceramics is unbelievably affordable. Very happy! ...read more

Out With The Old, In With Much Much Better

Summit RacingSummit Racing Verified Purchase

SUM-G9006-9
I installeed these headers on my 1972 Chevy K20 4X4. I was suprised by the finish,Very Nice. The old headers were a royal pain to change plugs. Hours spent getting them in and out. These new one look to be no problem changing plugs. Installation was straight foward and to to bad. I did have to cut and weld the drivers side rear tube (I hated doing it to that nice finish)but my clutch linkage situation left me know other choice. I looked to me that linkage mods may have been made at some point for the old hearer. No fault of Summit.. Attached to the Headers a brand new flow Master full exhaust system going from 2" to 2.5" the truck runs much better and sounds Great.. Great Headers Summit!! ...read more
