Looking to purchase a set of long tube headers for my 5.7 vortec. I will be doing an EGR delete to broaden my choices for long tubes. Obviously I can’t narrow...

    Everyone's favorite paint for making headers look good again? 89 350 crate

    So the headers on my 89 350 tbi are probably 10 years old or more. Whats the most recommended paint that'll withstand that heat? Or wrap? I'm open to all suggestions. The flowmaster (Super40s I Think) are close to 20 years old so definitely wondering if I should pay the price for new true duals...

    O2 sensor on mid length headers

    Does anyone have any experience running the stock 1 wire O2 sensor on direct fit, mid length headers? I have a hole in my cat and rotted headers, so I am replacing the stock manifolds with JBA 1830S headers and cat with a Magnaflow 23256. I saw that long tube headers or relocating the sensor...

    98 5.7L Headers - Possibly stupid questions

    My truck is a 1998 K1500 5.7L, currently has stock exhaust down to the rear cats. I had to chop off the mufflers the other day because one of them blew in half, and they were both rattling. When I dropped the tailpipes to the floor a bunch of the catalyst material fell out of the mufflers, so...

    EGR Delete

    96-00 L29 454 Headers

    Hello folks, I've got a '99 K2500 with the 454 and I want to put some long-tube headers on it. I've seen sets on Summit and Jegs that say they are direct fit for my truck, but then they say they are only for up to '95. If anybody has any ideas, maybe a part number, that would be awseome. Thanks...

    93' K1500 complete exhaust question?

    I have a 1993 Chevy K1500 ext. cab short bed and want to know if anyone can suggest a good complete exhaust system from the headers back with no cats and true dual if possible? I want something that will breath really well, especially after I stroke the current 350 to a 383. Thanks!

    Gibson GP113S-C

    It seems like Gibson is the about the only one who makes headers for the l29. Are people happy with them? Is fitment good in a K-Series? Longevity? Plug wire issues? I need to put mufflers on when it comes out of storage. Wanting a 411 swap. Probably head gaskets due to it using...
