RPM Stainless Steel Race Weight Muffler
RPM's Race Weight pipe is not just light weight at only 5 Lb.'s, but it also provides phenomenal increase in throttle response while providing a staggering 3HP gain. This is a full stainless muffler that is a easy installation and direct fit to the stock OEM muffler. The muffler body is 4", this pipe sounds great but is by no means "quiet". Great for racing, mountain riding, or lower populated areas. Great sound, the best performance, and fantastic weight savings! What more could you ask for!?

Shipping times vary depending on your location and shipping method selected during checkout. Standard shipping typically takes 5-7 business days, while expedited shipping can take 1-3 business days.
Returns are only accepted if R1 Package Protection was purchased at checkout, which includes a 14-day return window, free shipping, and no restocking fees. Exchanges are allowed with or without R1 protect, though non-R1 protect exchanges are subject to fees and shipping costs. All items must be unused, in original packaging, and meet strict resellable condition standards to qualify.
Great question—fitment is everything when it comes to performance and safety. Every product page on our site includes a “Will this fit my machine?” section with detailed compatibility info. If you’re still unsure, give our team a call at 801-899-2520 or email support@r1industriesoffroad.com—we’ll confirm fitment before you buy, so you get exactly what you need the first time.

If you added R1 Package Protection at checkout, you’re fully covered! R1 handles lost, stolen, or damaged packages with zero hassle. If you didn’t purchase R1 protect, reach out to us at 801-899-2520 and we’ll do our best to help, but we strongly recommend protecting your order with R1 protect for full peace of mind.
Without R1 protect, all returns are subject to restocking fees —no exceptions. However, we do offer exchanges for qualifying items within 14 days of delivery, though fees and shipping both ways will apply. If you’re unsure about an item, we recommend reaching out before you buy—we’re here to help you get it right the first time.
