ENGINEERED FOR FL5 / DE5

SBX Performance FL5 / DE5 High-Flow Catted Downpipe

Built for the Honda Civic Type R FL5 and Acura Integra Type S DE5, this downpipe is designed to reduce post-turbo restriction, manage heat more effectively, and improve turbo efficiency where it matters most.

The SBX design uses a 4 inch off-turbo primary section directly off the turbo, transitions into a 4.5 inch GESI GEN2 Advanced G-Sport UHO catalyst (#85200, rated up to 850hp), then tapers to a 3 inch outlet to match the factory front pipe location cleanly.

4 in Turbo Outlet 4.5 in GESI GEN2 UHO #85200 3 in Outlet FL5 / DE5 Fitment
Premium hardware. Premium catalyst. Premium design. This is for buyers who want a properly engineered GESI-based downpipe — not the cheapest option on the market. Hand-built in the USA in limited production batches.

Why Rampage Fab Titanium Turbo Studs?

The turbo-to-downpipe connection sees extreme heat cycling and is one of the most difficult areas to service later. Premium titanium turbo studs improve corrosion resistance, future serviceability, and overall presentation compared with conventional plated hardware.

Every SBX downpipe ships install-ready with the lower JIS high-strength steel flange bolts and nuts, gasket, O2 extension, and heat shield spacer hardware — plus Rampage Fab titanium turbo studs included as standard at the turbo flange. Raw Titanium is the standard finish; Burnt Titanium is available as a +$20 upgrade.

Optional Add-Ons

OEM Honda Turbocharger Gasket B — +$89.99

Fresh OEM Honda turbo-to-downpipe gasket for customers who want a completely fresh install, or whose original gasket has already been removed before.

Your factory gasket can usually be reused if it is still in good condition.
