Parts & Accessories Spare parts For sale: New headers with downpipe and electronic muffler. Engine: 1fz. Fully custom-made by 4Speed Garage. I personally custom-made it a week ago, God is my witness. I installed it and the sound is excellent. Whoever wants a great sound, it was custom-made for 2700. It has no welding or anything, and its hoses are hidden. The headers have a hidden system with insulation. The muffler has two outlets. The car is comfortable even if you don't turn on the muffler. All its accessories are with it, complete. Reason for selling the headers: I sold the car.
