Upower Square Exhaust Tip Review: Transform Your Diesel Truck’s Look with Premium Chrome Styling

Whether you’re upgrading a work truck or adding the finishing touch to your diesel build, this 2.5″ inlet to 3″ x 5.5″ outlet tip has genuinely impressed us with its fit, finish, and durability.

First Impressions: Unboxing and Build Quality

The moment we pulled this exhaust tip from its packaging, the weight and shine told us everything we needed to know about build quality. Unlike flimsy chrome-plated tips that feel hollow and cheap, the Upower tip has substantial heft—a clear indicator of the quality stainless steel construction underneath that mirror-like chrome finish.

The polishing is exceptional. We’re talking showroom-quality chrome that reflects like glass, with no visible imperfections, pitting, or dull spots. The square outlet design measures exactly as advertised at 3″ x 5.5″, giving your diesel truck that aggressive, wide-stance appearance that separates it from round-tipped vehicles.

At 9 inches long, this tip provides excellent visibility from behind while maintaining perfect proportions. It’s long enough to make a statement without looking cartoonish or overdone—a balance that’s surprisingly difficult to achieve with aftermarket exhaust tips.

Installation Experience: Weld-On Design Done Right

We’ve installed dozens of exhaust tips over the years, and the weld-on design of this Upower tip is refreshingly straightforward for anyone with basic welding equipment. The 2.5″ inlet diameter is a common size that fits most diesel truck exhaust systems, including popular models from Dodge Ram, Ford Super Duty, and Chevy Silverado/GMC Sierra trucks.

During our installation on a 2018 Ram 2500 with a 6.7L Cummins, the tip slid perfectly onto the existing 2.5″ exhaust pipe with just the right amount of clearance for proper welding. The stainless steel material welds beautifully—we used standard TIG welding and achieved clean, strong beads that should last the lifetime of the vehicle.

A few installation tips from our hands-on experience:

• Mock-fit the tip before welding to ensure proper angle and positioning
• The 9-inch length gives you flexibility in placement—we positioned it to extend about 6 inches beyond the bumper for optimal appearance
• Clean both the exhaust pipe and the tip’s inlet thoroughly before welding for the strongest bond
• Allow adequate cooling time after welding before handling—stainless steel retains heat longer than you’d expect

Installation time was approximately 45 minutes, including preparation, welding, and cleanup. An experienced welder could easily complete this in 30 minutes or less.

Why Weld-On Beats Clamp-On Every Time

We specifically appreciate that Upower designed this as a weld-on tip rather than a clamp-on model. Here’s why this matters from our real-world testing:

Zero movement: Weld-on tips don’t vibrate loose, rotate, or shift position over time like clamp-on alternatives. After 3,000+ miles of testing including highway driving and rough terrain, our installed tip hasn’t budged a millimeter.

No exhaust leaks: Clamp-on tips frequently develop small exhaust leaks at the connection point. The welded joint creates a permanent, leak-free seal that maintains proper exhaust flow.

Cleaner appearance: Without visible clamps or hardware, the weld-on design provides a seamless, factory-quality look that’s far more professional.

Theft prevention: Unfortunately, chrome exhaust tips do get stolen from trucks. A welded tip requires significantly more effort to remove than a clamp-on, serving as an effective deterrent.

The Square Design Advantage: Stand Out from the Crowd

Let’s talk about why the square outlet design makes such a dramatic visual impact. During our testing period, we received more compliments and questions about this exhaust tip than any round tip we’ve ever installed. The 3″ x 5.5″ rectangular opening creates an aggressive, performance-oriented look that commands attention.

The square design isn’t just about aesthetics—it also has functional benefits we noticed during testing:

Wider exhaust dispersion: The rectangular opening disperses exhaust gases across a broader area compared to round tips, which we found reduces the concentrated soot buildup on the bumper directly above the tip.

Modern styling: Square and rectangular design elements are increasingly popular in automotive styling, particularly on diesel trucks. This tip aligns perfectly with current design trends while maintaining timeless appeal.
