Overview:

Each header is formed from specially selected .049 cold roll flash controlled tubing, and features FLOWTECH's exclusive, thick, mandrel-formed Power Plenum collector.

Fitment Notes:
- Will NOT fit with manual transmissions.
- Will NOT fit C6 transmissions (but fits other Automatic Transmissions).
- 351C-4V engines only!
- WILL fit models with AC, Power Brakes, and Power Steering.
- Breaking in an engine with ceramic coated headers WILL result in damage to the coating and will VOID all warranties. Ceramic coated headers require several heat cycles to fully cure before they will withstand extreme heat. Flowtech recommends using cast iron exhaust manifolds or old headers to break in new engines to avoid coating damage.
- The use of header wraps can cause the header tubes to crack or rust due to excessive heat and moisture build-up. Flowtech does not recommend the use of header wraps as this will void the warranty.

Convenient for travel
Good for travel when you may not have a glass, a spoon and a place to mix the powdered version with water. Make no mistake, you must still drink at least 8- 12 ounces of water with the capsules, and one serving is 5 capsules. But, this is a bulking agent,!so that is to be expected.

Surprisingly Great for Diarrhea + Dropped My LDL Big Time – Sugar-Free Winner!
Size: 2.3 Pound (Pack of 1), Style: Sugar Free 180 count
I started taking this Metamucil Sugar-Free 4-in-1 Psyllium Fiber mainly because I deal with diarrhea more than constipation (opposite of what it's usually advertised for). I was skeptical, but it worked amazingly well—firms things up, reduces urgency and frequency, and gives me normal, regular bowel movements without any cramping or worsening. It's gentle, mixes okay in water (orange flavor is tolerable, not too sweet since it's sugar-free), and I take 2 teaspoons daily.
Even better bonus: after a few months of consistent use, my LDL cholesterol dropped from 110 to 58! That's a huge win for heart health—I wasn't expecting that, but the psyllium fiber really does trap cholesterol and help lower it (backed by studies and Metamucil's own claims). No side effects for me, and it's affordable in bulk.
If you have diarrhea/IBS-D issues or want natural cholesterol support, this is worth trying (start low and drink plenty of water).

Metamucil 4-in-1 Psyllium Husk GLP-1 Friendly Fiber Supplement, Sugar-Free, 180 teaspoons, Orange
Size: 2.3 Pound (Pack of 1), Style: Sugar Free 180 count
I started taking Metamucil after my doctor recommended boosting my daily fiber intake, and I genuinely wish I had started sooner. This sugar-free orange flavor has become a non-negotiable part of my morning routine.
First, the taste — for a sugar-free supplement, it's surprisingly pleasant. The orange flavor is light and natural, not artificial or overpowering. Mixed into a glass of cold water, it goes down easily without that chalky, gritty aftertaste I dreaded from other fiber products I've tried in the past.
The 4-in-1 benefits are the real selling point for me. I've noticed a genuine difference in my digestive regularity, I feel fuller between meals (which has helped me make better snack choices), and my energy levels feel more stable throughout the day. As someone on a GLP-1 medication, I was thrilled to find a fiber supplement specifically formulated to complement that — it fills a real gap in the market.
The 180-teaspoon count is outstanding value. This container lasts a long time, which means fewer reorders and a lower cost per serving than most comparable products. The scoop is easy to use and the powder dissolves well with a quick stir — no clumping.
My digestion has genuinely improved since making this a daily habit. Less bloating, more consistency, and I just feel better overall. It's one of those quiet little wellness wins that adds up over time.
If you're on the fence, just try it. Simple, effective, great value — this is now a permanent fixture in my pantry. Cannot recommend it highly enough.
