Bought this M4 RM1 exhaust and after a couple of weeks the finish came off. I contacted M4 directly and they said they will not replace it. I sent several messages to this seller and after a week they denied my return without any explanation. Complete trash seller. Save your money and shop elsewhere and look for a better exhaust. This one also had fitment issues at the heads and leaks which causes additional popping. See for yourself on the photos that were taken at 1 month installed. ### ⭐⭐⭐⭐ GREAT SOUND ..DEEP ...Throaty *by J***G on Reviewed in the United States on October 17, 2018* Well first the good ...THE SOUND...it’s by far the deepest throatest exhaust I’ve found and I love it ..if you want that sharp ...sounds like a cat caught in a hell storm ..High pitched ...I’m trying to blow it up....buy one of the others I listened to just about all the different makes and M4 sounds best to me...installation wasn’t to bad but here’s why 4 not 5 stars.. I had a very had time trying to position the muffler so it wasn’t touching my swing arm...I had to twist it to the point the O2 sensor wouldn’t reach the plug so I had to Re route the sensor. I included a picture of the gap between the swingarm and muffler and it’s about a 16th of a inch and it’s already marked up my swingarm but even with that I wouldn’t change it to a different system again the sound is vastly different than most the other systems available I hope the read this and take a look at spacing..I’m sure I’m not the only one who’s had that problem ### ⭐⭐⭐⭐ Looks great. LOUD. *by E***. on Reviewed in the United States on December 22, 2019* Your browser does not support HTML5 video.  Exhaust arrived very quickly and packaged very well protected. Install was fairly easy and straightforward. Two things to note: the left flange nut on the left side (looking forward) header is partially blocked by the header pipe so getting my socket on that one to tighten it was a pain, recommend having a U-joint socket adapter or wobble socket to reach that one nut. Other thing is if you plan to plug the O2 sensor back in (a plug is included if you aren't) you will have to route the plug different from stock since the m4 exhaust has the hole on the opposite side. Other than that installation was good. This exhaust is EXTREMELY LOUD compared to stock it shocked me. Videos online do NOT come close to showing how loud it really is. Sounds amazing though completely changed the sound of the bike. Lots of popping on deceleration so a tune would be recommended. --- ## 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.vn/products/63825416-m4-2014-2020-yamaha-fz-09-rm1-full-system-exhaust](https://www.desertcart.vn/products/63825416-m4-2014-2020-yamaha-fz-09-rm1-full-system-exhaust) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-24*
