Province Auto Service Sdn Bhd
Mastering the Art of Exhaust System Sound Tuning for Malaysian Vehicles
Founded by auto enthusiast and former tuner mechanic Ah Tong after he accidentally perfected a custom exhaust note that made his 2008 Proton Wira sound like a race car at idle — Province Auto Service now specializes in fine-tuning exhaust systems to deliver the perfect blend of performance, tone, and compliance. Whether you want your car to whisper softly or roar confidently, we’ve got the expertise to make it happen.

Frequently asked
Yes, we're one of the few service centers in Selangor with the specialized equipment to rebuild the Garrett T307645A turbochargers used in 2JZ-GTE engines. Unlike generic turbo work, these units require precise wheel balancing at 100,000 RPM speeds using our imported SKF balancer, plus specific turbine blade profiling that requires a CNC machine capable of 0.001mm tolerance. We also have the original Toyota service manual with the exact torque specifications for the compressor housing bolts - most shops use generic torque values that can cause premature bearing failure.
For B18C engines, we use a specialized vacuum pump tester to measure the EGR valve's response at 300-400mmHg vacuum levels, which is specific to this engine's design. We've found that the original EGR valves from Honda have a tendency to fail after 120,000km due to carbon buildup causing the diaphragm to crack. Our repair process involves using a modified O-rings with silicone-based sealant and installing an aftermarket valve with better heat resistance. We also check for the specific exhaust manifold gasket failures that occur in these engines at around 150,000km.
Our VR38DETT specialists use a custom-built pressure testing rig that simulates the exact oil pressure conditions of this engine's high-performance oil system. We've found that these engines have a specific issue with the oil pump's relief valve popping at 120-130 PSI due to the stock pump's inadequate capacity. Our solution involves replacing with a high-flow OEM pump from the VR38DE version and using a modified oil cooler setup with 1.5mm thicker oil lines that prevent the pressure drops causing premature pump failure.
Yes, we've encountered the specific thermal shock failures in Mazda's 1.5L SKYACTIV-G catalytic converters where the ceramic honeycomb structure cracks after 60,000km due to rapid heating and cooling cycles. We use a specialized thermal imaging camera to identify which converter is failing before complete meltdown occurs. Our repair process involves using a replacement converter with modified internal catalyst coating that can withstand 1,000°C temperature swings without cracking - the stock converters typically fail at 80,000km due to this specific material fatigue issue.
