Does the Capristo Middle Silencer Spare fit my SL63 AMG?

Yes, if your car is an R231 Mercedes-Benz SL63 AMG from 2013 to 2020 with the 5.5 liter biturbo V8. It does not fit the V12 SL65 AMG, even on the same R231 chassis. Confirm your model and engine before ordering, since the SL63 and SL65 use different exhaust layouts.

Will these sport cats cause a check engine light?

Possibly. Because the 250 cell sport cats flow more freely than the Factory Equipment, the system can set a check engine light on some cars. The 250 cell option is the least likely of Capristo's three to do so because it keeps the most catalyst. An O2 sensor extension or an ECU tune clears a recurring light.

What is the Capristo Middle Silencer Spare made from?

It is made from T309 (1.4828) grade stainless steel, a heat-resistant alloy. Capristo hand-welds the section and hand-polishes it to a mirror finish at its own facility. The two 250 cell sport cats use a high-flow substrate of roughly 5.2 inches with the densest cell structure in the Capristo range.

Is this part street legal?

No. It is recommended for off-road and track use only and is not CARB approved, so it is not legal for sale or use in California or other CARB-compliant states. Check the rules in your state and your intended use before purchasing, as emissions enforcement varies by region.

Do I need the full Capristo exhaust to run it?

No. The center section works with a valved Capristo system or connects directly to the OEM exhaust. On the full Capristo setup the valves manage back pressure at low rpm and open at higher rpm so the sport cats flow freely, pairing this section with the Capristo rear silencer and EVCU valve control electronics.

What is the difference between the 100, 200, and 250 cell sport cats?

Cell count describes the density of the catalyst honeycomb. Fewer cells mean larger openings and more flow, so the 100 cell flows the most and the 250 cell the least of the three. The 250 cell version keeps the most catalytic material, which makes it the cleanest and most street-friendly choice while still flowing more freely than the Factory Equipment.

Description

Capristo Middle Silencer Spare w/ 250 Cell Sport Cats for R231 Mercedes-Benz SL63 AMG

The Capristo Middle Silencer Spare with 250 Cell Sport Cats gives the R231 Mercedes-Benz SL63 AMG a freer-flowing center section built the way Capristo builds everything, by hand, in heat-resistant T309 stainless, finished to a mirror polish. Its 250 cell sport cats open up the 5.5 liter biturbo V8 where the Factory Equipment holds it back, cutting restriction through the middle of the system for sharper throttle response and a deeper, more purposeful tone, while keeping the highest cell density of Capristo’s sport cat range so it stays the most street-friendly of the three. The section integrates with the car’s valved Capristo system or connects straight to the OEM exhaust, and it carries the hand-welded fabrication and German craftsmanship that make Capristo the choice of owners who want more from an already exceptional roadster without giving up the finish.

Craftmanship

Capristo develops each center section with 3D laser scanning, CAD design and CNC tooling at its German facility, then forms it from T309 (1.4828) stainless steel and polishes it by hand to a mirror finish. Capristo chose this alloy for its sound, its low weight and its resistance to sustained exhaust heat, which matters on a section carrying the full exhaust flow of the 5.5 liter biturbo V8.

About Capristo

Capristo is a German manufacturer of performance exhaust systems and carbon fiber components, building each system by hand at its own facility. Capristo exhausts are fabricated from heat-resistant T309 (1.4828) stainless steel, hand-welded, and polished to a high-gloss finish, and many systems pair with the company’s EVCU valve control electronics for programmable sound and flow. That original-equipment-grade fabrication and finish is what sets a Capristo system apart for owners of the finest German performance cars.

Additional Information

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.

Shipping Policy

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.

BP Pricing Difference

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
