Their kit fit great ! No clearance issues or anything ! Thanks for the suggestion! Less than $400 shipped with the bolts and the upgraded MLS gaskets !

That is AWESOME. I'm glad I could help you out. I recommend them when ever someone brings up headers/exhaust.. You cant beat there price for sure and they are great guys to deal with to.


Yeah, gave me a chubby hahaha. Sounds awesome man.

It sounds amazing! My bank account might be taking a hit soon, cause I want these now lol

Mine may be taking that same hit sooner than I was expecting.

Do you think it's worth it to get the long tube headers with the Y-Pipe, or just the headers? Curious cause at $350 for both it's very enticing

It depends if you want to lose the cats . Actually you'll have to either get the y pipe with the cats or without the headers won't work with the factory y pipe .

Thanks for the info. I guess whenever the time comes, I'll get the headers and y-pipe. Hopefully my neighbors won't hate me too much when that time comes haha

Yeah duramax's are lots of fun and very loud with the right mods haha. My tahoe is already fairly loud with a flowmaster Super 40, and here in Georgia, it's been down in the 50's in the morning, so I finally got a taste of a "cold" start earlier this week, and was surprised at the difference temperature makes in the sound. Makes me wonder just how loud it'll be with the headers.

How is it at cruising speed? If you had to drive 2 hours, is it tolerable?

What's better, 1 3/4 or 1 7/8? And would it be a negligeable difference? Looking to put these on my 03 that's getting a 6.0 soon.

Depends on your mods. I would say if you're going to stay mild with your mods 1 3/4 would be fine

Thx, I'm not gonna go crazy, just a cam and headers. I read you can use a stock LS3 cam for some cheap horsepower. Did I read correctly?

Video Time:

That's a video of a built 400 CI chevy with 1 5/8, 1 3/4, and 1 7/8 headers being run on it to see which size works best. For comparison, the 6.2L only comes out to about 379 Cubic inches.

For our engines, 5.3L - 6.2L, I would look past 1 3/4" headers unless you have a big power adder. Personally, unless I found that the stock manifold primaries are bigger than 1.5", I would probably go with the 1 5/8 to see if I could hold onto a little more of the bottom end torque.

Just after the crossover goes from 2 to 1 there's a flange. I cut the flange off of the old pipe and welded it to the new one. Bolted it up and was all done.
