**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.

Nice but better on tall men
We ordered this for a show. Our actor is 5’9” and the sleeves and legs are too long as well as the body of the tunic.I believe we ordered a medium. The waist fit and we could not go any smaller. In another review I have an actor who is 6’5” and very thin in the same size and it fits him well.

Cute Comfy Cultured 💕
Color: Burgundy With Gold, Size: Small, Color: Burgundy With Gold, Size: Small
I ordered all my boys the men's sizes because I needed the burgundy gold tones to match my dress. All their outfits were longer then need but was expected because they're not men! My 8yr old wore men's small, my 10yr old wore men's medium, 13yr old wore men's large and our taller 12yr old wore XL. They color was deep, the gold is a print not embroidery but they all were handsome and comfortable 💕
