**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.

Cute and Comfortable
Size: 10, Color: Black
This is my second pair. I bought the sand color at my local Macy's. I got their last pair. I have issues with back pain and ankle swelling and pain. These are so comfortable I had to get them in Black. The adjustable straps are great. My feet are a little bit wider because of the swelling issues. So if you have very narrow feet these might be a little big. You might want to go down a half a size. But otherwise I wear a size 10 and they fit perfectly. I don't think the picture does the color justice. The black almost looks like velvet, it's very deep and rich. I wore them out today for the first time and got lots of compliments. The footbed is very comfortable with the memory foam. Lots of support. I noticed my back and ankle pain is much better wearing these. I've never owned UGG before. If these hold up really well and continue to stay comfortable, I will be purchasing other styles for fall and winter.

My new favorite summer sandal!
Size: 8.5, Color: Bay Fog
I am loving these shoes so far this summer! The color is so cute, perfect for a light summer palette. It's the perfect light purple that doesn't make me look pale or washed out. For reference, I have fair to light neutral skin tone. They are SO comfortable - a little too comfortable for a shoe, it's more comfortable than my ugg slippers! They do take a second to put on as you have to either force your ankle in without unstrapping the back - don't judge me - or undo them. Thankfully they have a strap to help get them on easily. I love these shoes. I am a medium width, but I think these have some wiggle room since both the straps are velcro and adjustable somewhat. They are easy to walk in, hold onto the foot, have been more balanced than some others I have had in this platform style, and are very cushioned to walk in. Slight arch support to me but I have somewhat high arches so if you are more flat footed or standard arch these will give you even better support. Really impressed with these. They are more casual but work with many different outfits from sundresses to jeans. For me, these were a great buy and I will be wearing them all summer.

Style, Comfort
Size: 9, Color: Sand
If I could give a Ten Star review, I would. Hands down the most comfortable pair of sandals I have ever owned. I wore them 16 days straight while touring Italy. Comfortable and goes with all of your outfits. They pack well in a suitcase too. Light weight.
