SBX Competition Downpipe
The SBX Competition Downpipe is a straight-through exhaust component developed for dedicated race cars and closed-course competition builds. It is hand-built in the USA to the same fabrication and welding standards as our GESI catted downpipe, while providing an unrestricted exhaust path for maximum flow and rapid turbo response.
- Straight-through competition configuration, designed to reduce restriction and maximize exhaust flow.
- 304 stainless-steel construction, precision TIG-welded and hand-built in the USA.
- SBX Grade 5 titanium turbo studs included, our own Ti-6Al-4V hardware in PVD Black, Burnt, or Raw at no additional charge.
- Backed by a 1-year weld warranty.
Sold Out, Restricted Competition Product
This product is not openly offered for general consumer purchase or use on street-driven vehicles, and it is not stocked for direct online checkout.
Availability is limited to verified race teams, motorsports organizations, professional track-only vehicle builders, and owners of dedicated vehicles permanently configured for closed-course competition.
Supporting information regarding the vehicle, racing organization, competition series, shop, or intended closed-course application may be required before an order is approved.
Race teams only, please contact us directly at sales@sbxperformance.com to request eligibility review and product availability.
Built to the Same Standard as Our Catted Downpipe
Many straight-through pipes for these platforms are inexpensive overseas products or one-off garage builds. This is not one of them.
The SBX Competition Downpipe is fabricated to the same production standard as our GESI catted downpipe. It is produced by the same shop using the same 304 stainless steel, precision TIG welding, quality-control process, and carefully developed fitment.
If your only priority is finding the least expensive straight-through pipe available, this product may not be the right fit. It is built for race teams and competition builders who value proper fabrication, consistent fitment, premium hardware, and warranty support.

What's Included
- SBX Competition Downpipe
- 3-bolt lower flange gasket
- Lower flange hardware with JIS bolts and nuts
- SBX Grade 5 titanium turbo studs, set of four
- Choice of PVD Black, Burnt, or Raw titanium stud finish
- O2 sensor extension, as required by application
Important: The Competition Downpipe does not include factory heat-shield standoffs or mounting hardware. The factory downpipe heat shield does not reinstall on this competition configuration. Review the heat-management information below before installation.
Heat Management, Read Before Installation
Because the Competition Downpipe is used without the factory heat shield, proper under-hood heat management is strongly recommended.
- Recommended: form-fit downpipe blanket. A removable blanket helps control radiant heat in the engine bay and does not affect the weld warranty. The SBX Γ PTP Downpipe Blanket is designed specifically for this pipe and is available in Lava or Black Lava.
- Not recommended: exhaust or header wrap. Traditional wrap can retain moisture and excessive heat against the stainless-steel surface. Use of exhaust wrap voids the downpipe warranty.
Why SBX Titanium Turbo Studs?
The turbo-to-downpipe connection sees extreme heat cycling, and on a car that gets pulled apart between events it is one of the worst spots to fight. Seized, rusted studs are what turn a quick swap into a weekend and a set of extractors. Titanium doesn't gall and seize against the turbo housing the way plated steel does, so the next person in there has a much better day.
We make these in house now. Ti-6Al-4V Grade 5, the same alloy used for aerospace fasteners, cut to the correct length for the K20C1 turbo flange so you're not stacking washers to make something generic fit. Three finishes at the same price: PVD Black, Burnt, and Raw.
Want more of them? We sell the same studs as standalone kits in sets of 4, 7, and 11 for the rest of the K20C / L15B bay.
