headers

I have been trying to find either a set of 1-7/8 tsp headers with the offroad connection pipes, or just the connection pipes as i can still find the headers. Anyone aware of someone who sells them at a reasonable price seeing as no online retailers carry them anymore?

Recently picked up a set of used headers and I am trying to find information on the catalytic converters. From what I have gathered they are a gen 1 cat only good for vehicles up to 2016. Will this be an issue on my 2022 GT with a whipple? Also hoping I can stay on the whipple calibration with...

Hey everyone, after installing catless long tube headers, I’ve been having a ton of issues with my o2 sensors.. driver side fell off, and was ripped in half. Passenger side just caught on fire, and almost took my car with it. People suggested heat wrap or a o2 spacer to pus further away from my...

Hey everyone, I’m running into a mess after installing long-tube headers and I’m hoping someone has seen this before. Right now I don’t have a tune, my rear O₂ sensors aren’t plugged in, and I’m just running header dumps while I wait for my mid-pipe. Whenever I do a hard pull, my car throws a...

I just installed long tube headers on my 2016 Mustang GT (automatic, premium), and now: Steering wheel buttons are dead — horn doesn’t work, paddle shifters don’t work, and the button backlights are off. Airbag light is on. Hill Start Assist light keeps coming on, even though I have an...

As the title says, I'm curious to know if anyone has ever dealt with Yard Smart LLC on Instagram for any car parts or engines? Instagram: Tiktok: I've been looking into them and there are several things that I'm interested in for my car but they don't have a website and can only message...

Hey guys, I have a 5.0 with a Pypes X-Bomb and Valvetronics on it. I’m planning on doing headers (catted) but I don’t want the insane volume that comes with them. As of now I’m thinking I’ll throw some Vibrant Ultra Quiets on, but it’s really hard to find good comparison videos. If any of you...

Has anyone tried this? I hate to give 2M more publicity, but I really don't want to take my headers that don't clearance back off. I was thinking this might be an easier method. Thoughts? https://shop.2mfabrication.com/product/2015-mustang-ultra-clearance-steering-shaft?gQT=2

Hey team. Bought these a while back for a future project build, which changed over the years to a Predator engine built from the ground up. Due to the GT5 oil pan reservoirs, the driver side won't fit so I have to get GT5 specific for the project. Never installed, no bolts tightened. Go for $590...

posted a thread earlier this week asking for help and after doing more research and help from you all, im starting to understand. now, my only question would just be do i need to get o2 wire extensions for my headers? will the stock ones reach? have a 2016 GT and the headers are from Texas...

I'm looking to buy texas speed headers for my 15' mustang. I stumbled upon these used ones for a little bit less than half the price of new ones. So they cheap. The only thing holding me back from buying is the dents on the passenger header. The owner states that he had no idea that it was there...
