Review: Great exhaust! - Always heard great things about Invidia and wasn't let down! Be warned if you are looking for a quiet exhaust this might not be for you. It isn't super loud but definitely louder than stock by a lot. Fairly easy install and shipped quickly. Useful tip - use some spray such as wd40 to loosen up the stock exhaust from the tricky hangers that keep the exhaust in place. If you are wondering what it sounds like check it out on YouTube there are plenty of vids. Hope this was helpful!

Fit right on no issues. Loud and deep toned. Smell to it but that’s natural since it’s brand new. Arrived a few days early too which was a plus for me. I’m happy with my purchase. Oh and it’s for a 4 door si, not a coupe. If you copy the part code and do your research you’ll see. ## Frequently Bought Together - Invidia (HS12HC4GTT) N1 Cat-Back Exhaust System with Titanium Tip for Honda Civic Si Sedan - 3D LED Red SI Badge Emblem Light Front Grille Ornament Emblem For Honda Civic - ECOTRIC Rear Trunk Spoiler Wing Compatible with 2006-2011 Honda Civic 4 Door Sedan ABS Trunk Spoiler Wing Painted Gloss Black --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ro/products/6820104-invidia-hs12hc4gtt-n1-cat-back-exhaust-system-with-titanium-tip](https://www.desertcart.ro/products/6820104-invidia-hs12hc4gtt-n1-cat-back-exhaust-system-with-titanium-tip) --- *Product available on Desertcart Romania* *Store origin: RO* *Last updated: 2026-08-27*
