**2017-on  Honda Civic Si Coupe (only)**

The legacy of the GReddy SP lives on with GReddy’s best version yet, the Supreme SP and to prove it carries a limited lifetime warranty! From the 1st flange to the new double-wall GReddy Tip, each Supreme SP system features a high-quality, hand Tig-weld 304 stainless-steel outer construction. Within the muffler, new straight-through and directed- straight-though chambered muffler designs allow GReddy to engineer a more refine exhaust note while increasing exhaust flow and performance. Classic GReddy street performance styling is maintained with excellent fitment and a stylish exhaust system layout. The Supreme SP not only designed to perform and sound great for each specific application; it matches the vehicle’s body-lines and styling.

The unique dual muffler Supreme SP for the 10th generation Honda (FC3) Civic Si coupe features high-flow with a refined exhaust note. Under wide-open-throttle, spirited driving, the system offers the classic GReddy deep exhaust growl. To enhance the performance of the turbocharged 1.5L engine, this 3piece, cat-back exhaust connects to the factory piping (our system bolts to the factory exhaust system at the flange behind the engine/transmission) and expands to large 3” (76mm) forward-midpipe and mid-pipe that split to two polished, straight-through SP oval mufflers and dual center-exit dual-wall GReddy tips. This tip and muffler combination is a great compliment to the Si’s sporty, but wide rear bumper tip opening. (We also offer a similar, application-specific system for the (FC1) Civic Si sedan.)  Like all GReddy Supreme SP systems, the fully hand-welded 304 Stainless-Steel exhausts carry a Limited Lifetime Warranty.

Dream pillow
I’ve been using latex pillows for over 30 years, and I can’t find them in local stores anymore. I’ve been needing to replace my pillow and finally decided to try this one. There are so many options on Amazon that it’s overwhelming. But this standard low loft pillow ended up being PERFECT. It feels amazing and just like the pillows I’ve been using since childhood. It is soft but cradles my head and neck perfectly. For me, it’s like sleeping on a gentle cloud. Very happy with my purchase. (Yes, it does have a slight latex odor. That is normal due to the material. It’s not very strong and it doesn’t bother me).

Great latex pillow
Size: Queen (Mid Loft), Number of Items: 1
This review is for the biamktp queen pillow. Medium firmness. Finally a latex pillow worth keeping. After trying many other latex pillows I'm finally sleeping comfortably. This pillow is soft, yet firm enough to give your head support. I'm not having any neck or shoulder pain when I wake up. I'm sleep on my side about 95% of the time. 5% on my back. I've been sleeping with this pillow for about 10 days and still am happy with it. It was delivered on time, absolutely no odor and it has a removable cover. I highly recommend it.
