Fit great, came with needed hardware and gaskets, not terribly loud, and looks almost factory. ### ⭐⭐⭐⭐⭐ 2015 Civic Si Sedan *by B***1 on May 23, 2015* I ordered this for a 2015 Civic Si Sedan. It fits like a glove and the sound is amazing. The quality of the exhaust is insane compared to the stock one that came with my Si. Sound is there but its not an obnoxious ricer sound, the best way i could describe it is that its deep throaty groan that will literally put a smile on your face as your brain translates it to pure performance. I do not have a single regret ordering this exhaust. ## Frequently Bought Together - Invidia (HS12HC4G3S) Q300 Cat-Back Exhaust System with Stainless Steel Rolled Tip for Honda Civic Si Sedan - Acuity Shift Linkage Bushing Upgrade for the 2007-2017 Honda Civic Si, 2007-2017 Civic (MT), 2015-2017 Honda Fit (MT) - Rev9 R9-HS2-011_2 Hyper-Street II Coilover Suspension Lowering Kit, Mono-Tube Shock w/ 32 Click Rebound Setting, Full Length Adjustable, compatible with Honda Civic Si (FG/FB) 2012-13 --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/15050792-invidia-hs12hc4g3s-q300-cat-back-exhaust-system-with-stainless-steel](https://www.desertcart.vu/products/15050792-invidia-hs12hc4g3s-q300-cat-back-exhaust-system-with-stainless-steel) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-04*
