AUTOSAVER88 4 in Inlet Exhaust Tip 15 in Overall Length - Deep Tone

Our review of the AUTOSAVER88 4 in Inlet Exhaust Tip finds it best suited to drivers who want a simple, bolt-on way to upgrade exhaust looks and sound without welding. The single biggest reason to buy is its straightforward compatibility and build: a true 4 in inlet that clamps to 4.0 in outside diameter tailpipe outlets, made from high-grade stainless steel with a drainage hole to limit rust. Installation is bolt-on with an M8 fastener and it produces a deeper rumble at idle thanks to its rolled-angle cut and thicker inner wall.

Key Features

• Exact fit for 4 in outlets: The 4 in inlet is designed to fit directly on tailpipes with a 4.0 in outside diameter so you get a snug, simple connection without modifications.
• Stainless steel construction: High-grade stainless steel helps resist heat, deformation and corrosion so the tip protects the tailpipe and maintains appearance over time.
• Black powder coat finish: The powder coated surface gives an elegant, low-profile look while hiding soot and blending with dark rear bumper trims.
• Sound enhancement: Rolled-edge angle cut and a thicker inner wall change exhaust tone to a deeper rumble with occasional crackle, adding character without a full exhaust swap.
• Drainage hole: A built-in drainage hole sheds water away from the tailpipe junction to reduce trapping moisture and slow rust formation.
• Bolt-on installation: The M8 bolt-on design mounts with an Allen key and avoids drilling or welding for quicker, reversible fitting.

Who It's For

This tip is aimed at owners of trucks, vans, or cars that already have a 4.0 in outside diameter tailpipe and want an easy visual and acoustic upgrade without changing the main exhaust system. It particularly fits drivers who value a sturdy, welded collar and prefer a bolt-on solution they can fit at home or have fitted quickly by a shop.

Those who should look elsewhere include owners whose tailpipes are not 4.0 in outside diameter, and drivers seeking significant performance gains rather than cosmetic and sound changes, since this accessory is decorative and tonal rather than a power-focused modification.

Pros & Cons

Pros

• Solid built quality with a robust welded section and bolt/stud that customers report fits well on stock piping.
• Improves rear-end appearance with a sleek black powder coat and rolled-angle cut.
• Produces a deeper idle tone and light crackle without major exhaust work.
• Easy bolt-on installation with no welding or drilling required.

Cons

• Finish can chip over time if subjected to abrasion or harsh conditions, so careful maintenance is needed.
• Only fits tailpipes with a 4.0 in outside diameter, so sizing must be checked before purchase.

Frequently Asked Questions

Will this fit my vehicle?
It will only fit if your existing tailpipe has a 4.0 in outside diameter; measure the outside of the pipe before buying.

Does installation require welding?
No, the tip uses a bolt-on M8 fastener and can be tightened with an Allen key without drilling or welding.

Will it prevent rust?
The stainless steel body and drainage hole reduce rust risk, but regular cleaning and maintenance are recommended to keep the finish intact.
