AFE Power 48-46207-PK aFe Twisted Steel Y-Pipes | Atech Motorsports

aFe Twisted Steel Y-pipes (48-46207-PK) merge the dual exhaust banks into a single collector with minimal flow disruption. The Y-pipe is a critical component in V6 and V8 exhaust systems a poorly designed Y-pipe creates turbulence that robs power across the entire rpm range. aFe's Twisted Steel Y-pipe uses smooth merging transitions to maintain exhaust velocity through the collector. The design reduces backpressure at the merge point for improved engine efficiency.

Constructed from mandrel-bent aluminized steel with inlet diameters matching factory downpipe outlets at 2.25 or 2.5 inches and a single 2.25-inch outlet. The merging collector uses a divided internal wall that prevents cross-bank interference between the two exhaust streams. Fully TIG-welded construction ensures durability under high-temperature operation. Gains average 5-10 hp by reducing backpressure at the merge point. The smooth transition maintains exhaust gas velocity for improved scavenging across the power band.

Bolt-on replacement using factory connections. All necessary gaskets and hardware are included. Direct fitment for the specified application with no modification required. Compatible with stock exhaust manifolds and aftermarket downpipes. Typical installation time is 30-45 minutes. aFe recommends using new gaskets during installation for a leak-free seal.
