Description

The HKS Stainless Steel Center Pipe (Silencer Delete) is a pure, performance-focused exhaust component engineered for maximum flow and power in competition GT-Rs. Derived from the high-power GT570/GT600 Racing Package, this pipe eliminates both the restrictive factory second catalytic converter and any internal silencing, creating a completely straight-through exhaust path. This version offers the absolute minimum exhaust restriction for the ultimate in power potential and aggressive sound, designated strictly for competition and off-road use.

Product Overview & Purpose

This is the no-compromise version of the HKS center pipe. It removes all exhaust restrictions between the downpipes and the rear exhaust section by deleting the second catalytic converter and omitting a silencer. The result is the maximum possible reduction in exhaust backpressure, leading to significant gains in horsepower, turbo spool, and throttle response in high-performance applications. It is intended solely for environments where noise and emissions are not regulated.

Product Highlights

⚡ Ultimate Straight-Through Flow for Max Power
This pipe provides the most direct and unrestricted exhaust path possible in its category. By removing the catalytic converter and any internal baffling, it achieves the absolute lowest level of exhaust gas restriction, which is critical for extracting maximum horsepower in heavily modified and competition-tuned GT-Rs.

🔧 Racing Package Proven Pedigree
This component is a direct carry-over from the proven HKS GT570 and GT600 Racing Package builds, ensuring it is engineered to withstand the demands of extreme power levels and track abuse. Its design is validated on some of HKS’s highest-performing GT-Rs.

🎵 Aggressive, Unfiltered Exhaust Note
Without a silencer, this pipe will produce a loud, raw, and aggressive exhaust sound that fully expresses the character of the VR38DETT engine. The tone is direct and unfiltered, intended for the race track where sound levels are a secondary concern to performance.

⚠️ Strictly for Competition Use – Not Street Legal
This product is for competition use only. It does not contain a catalytic converter and does not include a silencer, making it non-compliant with street emissions and noise regulations in virtually all regions.
