TOMEI EXPREME Ti Full Titanium Exhaust System

For 1985–1987 USDM Toyota Corolla Sport GT-S AE86 & 1983–1987 JDM Toyota Corolla Levin / Sprinter Trueno AE86 with 4A-GE / 4A-GEU

Overview

The TOMEI EXPREME Ti Full Titanium Exhaust System is a lightweight performance exhaust for 4A-G-powered Toyota AE86 applications, covering the USDM Corolla Sport GT-S and JDM Corolla Levin / Sprinter Trueno.

This listing combines TOMEI's two AE86 exhaust configurations into one product: Type-R – Under-Axle and Type-S – Factory-Style Route. Both use full titanium construction, 60.5 mm main piping, 1.0 mm pipe-wall thickness, and a large 89.1 mm single exhaust exit. The main difference is the routing and silencer design.

The Type-R uses a direct under-axle layout with a compact center silencer and the lowest overall system weight. The Type-S follows a more conventional factory-style route with a larger rear silencer. Both configurations cover the verified USDM GT-S and JDM Levin / Trueno 4A-G AE86 applications listed below.

Key Features

  • Full titanium construction for substantial weight reduction compared with conventional steel exhaust construction
  • 60.5 mm main piping on both Type-R and Type-S configurations
  • 1.0 mm pipe-wall thickness
  • Large 89.1 mm single exhaust exit
  • Type-R under-axle routing with compact 102 mm center silencer
  • Type-S factory-style routing with larger 152 mm rear silencer
  • Type-R exhaust-system weight of approximately 8.16 lb / 3.7 kg
  • Type-S exhaust-system weight of approximately 9.37 lb / 4.25 kg
  • Designed for USDM Corolla Sport GT-S and JDM Corolla Levin / Sprinter Trueno 4A-G AE86 applications
  • Removable sound reducer included with both configurations

Type-R vs. Type-S

Specification Type-R – Under-Axle Type-S – Factory-Style Route
Construction Full titanium Full titanium
Main Pipe 60.5 mm 60.5 mm
Pipe Thickness 1.0 mm 1.0 mm
Routing Under-axle Factory-style
Silencer 102 mm center silencer 152 mm rear silencer
Exhaust Exit 89.1 mm single exit 89.1 mm single exit
Exhaust Weight 8.16 lb / 3.7 kg 9.37 lb / 4.25 kg
Primary Distinction Lightest, most direct layout Conventional AE86-style routing
AE86 Market Application USDM GT-S / JDM Levin & Trueno USDM GT-S / JDM Levin & Trueno

The Type-R is the more weight-focused configuration. Its under-axle routing and compact center silencer reduce the complete exhaust assembly to approximately 3.7 kg, making it the lighter of the two options.

The Type-S retains the benefits of full titanium construction while using routing closer to the conventional AE86 exhaust layout. Its larger rear silencer brings total exhaust weight to approximately 4.25 kg, still exceptionally light for a complete performance exhaust.
