XinDeLeiHuan 4in T304 Stainless Steel Exhaust Pipe 17.3in Polished Flared Slip-Fit Connector

A polished 4" T304 stainless steel straight exhaust tube with a flared slip-fit end, designed as a universal 4-inch connector for cars, trucks and motorcycles.

This XinDeLeiHuan exhaust tube is a precision mandrel-straight section made from corrosion-resistant T304 stainless steel and finished with a mirror polish. It’s built to join or extend 4" exhaust systems, turbo piping, or custom fabrications with a simple slip-fit or weld. The combination of constant-diameter mandrel bending and a flared end gives reliable fitment for clamp-on or welded installations while keeping flow losses minimal.

Will this 4" pipe fit my vehicle’s existing exhaust?

Measure the outer diameter of your current pipe where you intend to join. This connector is intended to work with most systems that accept a 4" outer-diameter tube and can be used with clamps or welded into place for a permanent join.

• Designed for 4" outer diameter compatibility.
• Flared slip-fit end reduces alignment hassle during installation.
• Works with clamp-on couplers or standard exhaust welds.

How does the T304 stainless and mandrel-straight design help performance?

T304 stainless resists rust and holds up under high exhaust temperatures and road exposure, extending component life. Mandrel-straight tubing keeps internal diameter constant through bends and sections, which preserves exhaust flow and reduces turbulence compared with crushed or irregular tubing.

• T304 resists corrosion for longer service life in harsh conditions.
• Mandrel-straight maintains consistent diameter for smoother flow.
• Polished finish helps resist surface oxidation and eases cleaning.

What installation options are available and how easy is it to fit?

The flared end is intended to slip over or into a mating pipe, simplifying alignment for do-it-yourself installs and professional shops alike. You can secure it with exhaust clamps for a removable connection or weld it for a permanent, leak-resistant bond. Basic metalworking tools are sufficient for clamp installations; welding requires standard TIG or MIG techniques.

• Slip-fit flared end for quick alignment and clamp-on attachment.
• Weld-ready construction for permanent joints.
• Compatible with common exhaust clamps and hanger setups.

What are the product dimensions and finish details I should expect?

This listing describes a straight 4" internal/outer tubing section with a flared end and an overall length of approximately 17.3" (measure before purchase for tight fits). The tube is polished to a bright finish to improve appearance and resist staining from heat and road contaminants.

• Approximately 17.3" overall length for mid-length connector applications.
• 4" diameter compatibility designed for common exhaust sizes.
• Mirror-polished exterior for a professional look and easier maintenance.

Who is this for: This XinDeLeiHuan 4" T304 polished straight tubing is aimed at vehicle owners, custom exhaust builders, fabricators and DIY mechanics who need a durable, easy-to-fit connector for 4" systems. If you’re modifying turbo piping, extending a tailpipe, repairing a damaged section, or refining an aftermarket exhaust, this durable stainless piece offers a versatile, corrosion-resistant option. Always confirm measurements and intended clamp/weld method before ordering.
