Fitment Notes:

  • Pontiac V8 Engines Only!
  • Will not fit Firebird/Trans Ams with column shifted standard transmission.
  • Must modify stock exhaust to retain catalytic converters.
  • Will not fit Ram Air vehicles.
  • End holes on head must be drilled and tapped to ensure proper seal.
  • 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 recommend 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.

Warm, cozy, soft, 💜 love
I don't leave reviews very often (yes that is cliche) I just don't have time. I have been debating for a few months one what I actually wanted to do with my bedroom. Spring is coming and the dark is getting to me and wanted to still get an elegant feel. I have some light baby blue around in my other comforter but I needed lighter brighter. I saw this and how SOFT is looked and I LOVE soft and cozy, who doesn't? I am so glad I took the chance. With that I also ordered the pillow....what I thought were pillows but didn't read very clearly they were just the covers so I ordered pillows then the picture I knew would still be elegant but be able to tie all the peices in and OFF the internet. Sometimes colors are not the same online as in person since monitors are always different shades of a color. Now on to this comforter. I didn't realize it came with the pillow covers. 💜 the set comes vacuum sealed but it is heavy when vacuumed. I undid the packaging a day later when I had time to wash. The cover flew out and I was perplexed, it's a pillow cover!!!! Awesome!!!! Ohhh there's 2, woohoo! Omg it's so soft. Oh I'm in heaven. Mmmmm hugging the pillow cover, I knew this was my kinda softness bed comforter. It is not LIGHT weight like say a throw blanket but it is light vs heavy bulky goose downs even though they say those are light. And when you wash it, its def not heavy if u spin the water out at super high setting on ur washer. I was able to carry it to the dryer fairly easy 20 ft away. This is by far the BEST comforter I bought in my life. I am a hoarder when it comes to comforters. Thinking if I'm ever homeless I'll have lots of somethings to keep me warm. For the price and the quality, (the batting inside doesn't shift when washing) this will be another purchase in the future in another color so I can start a soft collection. I usually give my comforters that I dont use ( the oldest but still perfect condition) to a friend or homeless. Great product!!!!

Soft warmth for cold nights
Color: Charcoal, Size: King
This bedding set with faux mink fleece and sherpa backing is perfect for cold weather or low-heated rooms. It’s ultra-soft on both sides, and the down-alternative fill keeps warmth in without feeling heavy. The reversible design lets you switch up the look, and the stitching holds up well. Even after several washes, it keeps its texture and shape. No clumping or loss of loft. A practical choice for anyone who wants comfort, warmth, and simple style.

Great bedding at a great price!
Color: Tide Pool Blue, Size: King
I can’t believe how great this is for the price! Super soft, comfy and very warm. Perfect for wintertime. I don’t think I’d use it for other seasons…but it’s great right now.

Warm, soft, cozy… not very fluffy though
Color: Tide Pool Blue, Size: Full/Queen
I LOVE this comforter!! The color is beautiful, it’s super soft, it’s nice and warm, and it has a nice weight to it. I will say it isn’t as fluffy as it seems in the pictures, there doesn’t seem to be any filling between the 2 layers, and if there is, it’s minimal. It’s more like the thickness of a similar double sided throw blanket. It also has the tendency to grab any small debris which clings to it, but this is to be expected with this type of fabric. I would not recommend this comforter for pet owners as it will definitely be covered in hair and whatever else your furbabies may track in! Despite the lack of fluffiness and it constantly holding on to any loose thread or other random debris, I am still very happy with my purchase. Very good comforter for the price and it looks beautiful on the bed!!

I originally got the King set & loved it so much I ordered another in Queen size!
Color: Charcoal, Size: King
I didn't add a picture because the advertised picture is exactly what it looks like (and my beds not made at the moment, lol). It's so soft, comfortable, cosey and warm. It's thicker and fluffier than I expected, but still very lightweight. The price was great for a king size bed with 2 king sized pillow cases! I love it so much I ordered a second set in Queen size, just to have the cases for my smaller queen pillows that go in front of the King pillows and to have the extra blanket as a cozy throw. The only drawback is it does snag easily on rings, fingernails, etc. (also another reason I ordered the second one to lay across the places that I've snagged & a few that were already snagged when I got them). However, it's so cozy that I didn't want to go through the hassle of sending it back and having to wait for a new one! I'm very glad that it was suggested as an add on when I ordered the mattress pad & that I chose to add it on. I'd definitely recommend it to anyone!
