Quick answer: D.Box (ExhaustUpgrade) supplies model-specific exhaust tips in six main surface finishes - gloss black, matte black, mirror silver, brushed silver, sandblasted gray and burnt blue (bluing) linings - covering BMW, Mercedes-Benz, Porsche, Audi, Land Rover and universal applications. Every finish is catalogue-coded by chassis (for example JC-PORSCHE-020 for the 17-22 718 GTS split round in Silver/Black/Brushed Silver), and dealers can request the full finish list from D.Box at info@exhaustupgrade.com or WhatsApp +86 151 0516 7588. Material grades and MOQ are not listed in the public catalogue: please confirm with our team.
Why Surface Finish Is a Stocking Decision, Not a Detail
For a parts retailer or installer, the exhaust tip is one of the most visual products on the shelf. Two tips with identical shape and fitment can sell at completely different speeds depending on finish: a gloss black tip moves fast with owners of blacked-out SUVs, while a mirror silver tip is the safe default for luxury sedans. Because D.Box produces the same tip shapes in multiple catalogue finishes, wholesalers can cover several customer tastes with one fitment family instead of one SKU per taste.
This guide explains each finish in the catalogue, shows which real catalogue models carry it, and gives a simple stocking logic for dealers buying exhaust tips in bulk.
The Surface Finishes in the D.Box Catalogue

| Black (gloss black) | Deep gloss black coating | Porsche 718 kit shown above, gloss black version; Black Knight square series | Blacked-out builds, SUVs, M/AMG-style styling |

Note: on several M type carbon fiber split rounds the lining is selectable - catalogue options are Silver, Black, Sand blast or Bluing - while the outer shell can be Matte Black or Bright Black. That means one fitment can be ordered in up to eight shell/lining combinations. Exact combination availability per model: please confirm with our team.
How Dealers Can Build a Finish Mix That Sells
| Customer type | Recommended finish | Reason |
|---|---|---|
| OEM replacement (tip damaged or rusted) | Mirror silver or OE-style square, Silver/Black | Customer wants the car to look factory-original |
| SUV styling upgrade (X5, Cayenne, GLE, Defender) | Gloss black square, or square with decorative frame | Black squares dominate current SUV styling trends |
| Sports car / coupe owner (718, 911, M4, C43) | Brushed silver or carbon fiber shell with bluing lining | Performance look without full chrome shine |
| Dark-themed build (blacked-out trim) | Matte or bright black shell, black lining | Matches window trim, grilles and wheels already blacked out |
| Show car / track style | Carbon fiber M type with bluing lining | Most aggressive visual statement in the catalogue |
A common starting ratio for a mixed-stock order is roughly 40% silver, 40% black and 20% special finishes (brushed, sandblasted, bluing lining, carbon fiber). Adjust after your first season of sales data.

Packing Notes for Mixed-Finish Orders
Each catalogue model lists a carton packing size (for example 33x21x22 cm for JC-BMW-054, 30x22.5x16.5 cm for JC-PORSCHE-020, 46x27x30 cm for JC-PORSCHE-024), so mixed-finish orders can be planned carton by carton. Whether black, silver and brushed versions of the same model can share one carton, and how finishes are labelled on the outer box: please confirm with our team before placing a mixed order.
Fitment Comes First, Finish Second
A finish only sells if the tip actually fits. D.Box codes every tip by chassis code (G20, W213, 718, Cayenne and so on) and by installation type - original car installation, clamp-on over the stock pipe, or welded simple exhaust kits like the Porsche 718 set shown in this article, which ships with link pipes and four clamps. Before ordering any finish, confirm the chassis code and model year of the target vehicle, then choose the finish. If you are unsure which catalogue model matches your customer's car, send the chassis code to info@exhaustupgrade.com and the team will confirm the correct model number.
Frequently Asked Questions
Which exhaust tip finish is easiest to resell?
Mirror silver and gloss black are the easiest finishes to resell because they cover both OEM-replacement and styling customers. Brushed, sandblasted and bluing finishes sell in smaller volumes but usually to buyers who specifically want that look and are less price-sensitive.
Does the bluing lining fade over time?
Bluing is a heat-tone finish on the inner lining of the tip. Long-term durability data for each finish is not published in the D.Box catalogue: please confirm with our team before making any durability claim to your customers.
Can I order one model in several finishes in the same shipment?
Yes in principle - most catalogue models are produced in Silver/Black at minimum, and Porsche models such as JC-PORSCHE-020 list Silver/Black/Brushed Silver. Carton mixing rules and MOQ per finish: please confirm with our team.
How do I know which finish matches the factory look of my customer's car?
Match by chassis code and model year first. For OE-style replacements, silver matches most factory stainless tips, while gloss black matches blacked-out factory editions such as Black Knight style models. Send the chassis code and model year to D.Box and the correct catalogue model will be confirmed for you.
