Compact and lightweight, it enables accurate air/fuel ratio monitoring without welding, making it ideal for road and dyno tuning on non-catalytic vehicles. ## Description The Innovate Exhaust Clamp for O2 Sensor features a Patent-pending, Venturi-effect, tapped exhaust clamp for obtaining accurate lambda measurements in non-cat autos or other engines. Review: Works very well, useful for tuning!! - I use this tool for road tuning pretty often. Apart from the reviews saying to tape it to the exhaust (which I have done) it’s a solid purchase! Great for tuning on the road, and on the dyno. Highly recommend!! Review: Well built, Very high quality. - I ordered this tailpipe clamp because i wanted to be able to monitor air/fuel ratios without having a fitting welded into my exhaust pipe. The clamp worked as expected and the build quality is top notch. The clamping screw CAN loosen after a while so some duct tape should be used if you plan to drive the vehicle during the test. Also i read that it's best to place the wide band O2 sensor upstream of catalytic converter so that should be something to consider before buying this. The vehicle that I am testing does not legally require a cat so that's not an Issue for me. ## Features - Package Dimensions: 2.032 H x 17.018 L x 8.89 W (centimetres) - Country of Origin : China - Made out of industry grade Cast-Stainless Steel - Package Weight: 0.55 pounds ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000CO9MF8 | | Best Sellers Rank | #497,297 in Automotive ( See Top 100 in Automotive ) #341 in Automotive Replacement Exhaust Clamps | | Brand | Innovate Motorsports | | Customer Reviews | 4.6 4.6 out of 5 stars (269) | | Date First Available | November 23, 2005 | | Item Weight | 10.2 ounces | | Item model number | 3728 | | Manufacturer | Innovative Motorsports | | Manufacturer Part Number | 3728 | | OEM Part Number | 3728 | | Product Dimensions | 10 x 7 x 2 inches | ## Images ![3728 Exhaust Clamp Cast-Stainless - Image 1](https://m.media-amazon.com/images/I/41s1UOrmtgL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works very well, useful for tuning!! *by R***L on February 16, 2025* I use this tool for road tuning pretty often.

I was just guessing before but now I have everything I need to test the car to my skill level. I hope to install bungs one day but really, might not need to. I can use it in friends cars too. ## Frequently Bought Together - Innovate Motorsports 3728 Exhaust Clamp Cast-Stainless - AEM 30-0300 X-Series Wideband UEGO AFR Sensor Controller Gauge - HP Tuners PROLINK+ Cable with Analog and CAN Bus inputs for External Sensors Using MPVI2+ and MPVI3 OBD2 Scan Tools, Cable Only --- ## 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.hr/products/4341787-3728-exhaust-clamp-cast-stainless](https://www.desertcart.hr/products/4341787-3728-exhaust-clamp-cast-stainless) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-07-18*
