AUTOSAVER88 4 in Inlet Exhaust Tip 18 in Overall Length - Polished

In this review the AUTOSAVER88 4 in inlet exhaust tip is evaluated for drivers who want an easy cosmetic and acoustic upgrade for a 4.0 in tailpipe. The bottom line: it is a bolt-on, stainless steel tip that looks polished and delivers a deeper, rumbling sound without welding or cutting, so it is best for owners who need an instant visual refresh and slight sound enhancement. Fit is strictly for 4.0 in outside diameter pipes, so measuring your tailpipe before purchase is the single most important step.

Key Features

• Standard dimensions: The 4 in inlet, 10 in outlet and 18 in overall length give predictable coverage and a bold visual extension without overhanging the bumper.
• Universal 4 in fit: Designed only for tailpipes with a 4.0 in outside diameter, which ensures a snug, bolt-on installation when the size is correct.
• Stainless steel construction: High-grade stainless resists heat and deformation while the chrome-plated polished finish maintains bright appearance under road conditions.
• Sound enhancement: Rolled angle cut and thicker inner wall design produce a deeper rumble and occasional crackle for a sportier exhaust note.
• Drainage hole: Built-in drainage allows water to escape and helps reduce internal corrosion over time.
• Bolt-on installation: The included bolt-on clamp with M8 Allen fastener removes the need for drilling or welding and makes fitment straightforward.

Who It's For

This exhaust tip is best for car owners who have a 4.0 in outside diameter tailpipe and want an affordable way to change the look and tone of their vehicle without extensive modification. It suits daily drivers and weekend enthusiasts who prefer bolt-on parts and a polished chrome finish that cleans up the rear appearance.

It is not for vehicles with differently sized tailpipes or for buyers who need a performance exhaust system; this is an accessory for sound character and styling rather than power gains. Those who want custom welding, integrated muffler changes, or electronic exhaust controls should look elsewhere.
