AUTOSAVER88 4 Inch Inlet Exhaust Tip - Black Powder Coated Sound

In this review the AUTOSAVER88 4 inch inlet exhaust tip is evaluated for drivers who want an easy bolt-on visual upgrade and a deeper, more aggressive exhaust note without welding or custom fabrication. The tip is designed specifically for 4.0 in outside diameter tailpipes and the biggest reason to buy is its combination of durable stainless steel construction, a rolled angle cut that affects sound, and a straightforward M8 bolt-on installation that fits most vehicles with a 4 in tailpipe.

Key Features

• Standard dimension: The 4 in inlet, 10 in outlet and 15 in overall length provides a substantial visual extension that suits larger tailpipe openings while remaining universal for 4 in outlets.
• Durable material: Built from high-grade stainless steel, the tip resists heat and deformation so it maintains shape and appearance with regular driving.
• Black powder coat finish: The coating gives a low-gloss, elegant look that hides soot and complements darker bumpers while adding a protective surface layer.
• Sound enhancement: The rolled-edge angle cut and thicker inner wall produce a rumble and occasional crackle that many drivers find gives a sportier exhaust tone.
• Drainage hole: A built-in drain helps shed water and reduce internal corrosion risk, extending the life of the tip and the visible tailpipe area.
• Easy bolt-on fit: The M8 Allen key bolt-on design lets you fasten the tip without drilling or welding, making installation practical for DIY or quick shop fitting.

Who It's For

This exhaust tip is best for owners of trucks, SUVs, and cars that already have a 4.0 in outside diameter tailpipe and want a quick visual and acoustic upgrade without major modification. It suits drivers who prefer a darker, understated look and enjoy a deeper exhaust tone that is noticeable but not extremely loud.

It is not intended for vehicles with tailpipes of any other outside diameter, and anyone seeking major performance gains or custom-fitted fabrication should look elsewhere; professional installation is recommended if fitment questions or corrosion repair exist.

Pros & Cons

Frequently Asked Questions

Only if your tailpipe outside diameter measures 4.0 in; confirm that measurement before purchase.

Is welding required?
