Toyota Celica (1989-1993) GT4 3" Turbo Exhaust System
3" Stainless Steel Exhaust Upgrade for ST185 Toyota Celica GT4 (1989-1993)
The Toyota Celica GT4 is one of the most famous performance cars due to it's rally heritage - now a sort after classic!
Unfortunately the factory Toyota exhaust is very restrictive for sound and emissions.
Upgrading the Toyota Celica GT4 exhaust system is a great way to build horsepower, free up trapped torque, and improve upon restrictive factory systems. The larger pipes, low-restriction mufflers, and tuned resonators of a well-designed performance exhaust system can make a world of difference on your vehicle.
The net result is lower auto exhaust back-pressure, more horsepower, more torque, and a much better sound.
- Made of high quality 3" T-304 stainless steel
- Dyno proven increase low end torque and horse power
- Smooth and deep tone sound
- Dual 2.5" exhaust tip
- 89-93 Toyota Celica GT4 2.0 Turbo
All Empire Performance Exhausts feature:
Mandrel Bent Piping
Empire Performance exhausts comprise of mandrel bent, stainless pipe work, delivering uncompromising flow, performance, and sound. Mandrel bending involves placing a mandrel inside the piping, before it is bent to shape. In comparison; cheaper press bending from other manufacturers squashes the tube as it is bent, reducing flow.
304 Grade Stainless Steel
Tired of your mild steel exhaust systems rusting out after a year or less? Time to shop for a stainless steel system? There’s still some things you need to be aware of. Our competitors typically advertise their exhaust products as stainless steel. Most don't stipulate the differences between 409 grade stainless steel and 304 stainless steel and many customers are fooled into an inferior product
Significant differences exist between the metals that make one better for performance exhaust applications than the other. Let us explain
The corrosion resistance of your exhaust depends on the content of chromium and nickel found in the alloy. It is 409 grade stainless steel is used by many manufactures due to its medium strength, formability and very low cost. Typically, 409 grade stainless steel has a chromium content of between 10.50% - 11.75% and a nickel content of less 0.50%.
Empire Performance exclusively uses 304 grade stainless steel for performance exhausts because of its strength and the fact it is impervious to rusting, because it has around 20% chromium and 10% nickel content in the alloy. However, because of its low ferrous content, it can develop a golden colour when exposed to high heat over time. In fact, the ferrous metal content is so low that magnets won’t stick to it, making the identification of 409 and 304 grade stainless steel very easy.
Put simply, 304 grade stainless is the highest quality material used in the auto exhaust game when strength, corrosion resistance and performance are at the top of your list of priorities.
Empire Performance exhausts are exclusively constructed from high quality 304 grade stainless steel. Type 304 steel is engineered with chromium and nickel content and proves to be resistant to oxidation, corrosion, and durability.
Together with a polished finish - it is the best choice for your car offering unrivaled corrosion resistance from exhaust emissions, moisture and salt exposure.
