FLASHARK's downpipes are designed to seamlessly fit in place of your restrictive stock downpipes, which are situated immediately after your catalytic converters. Upgraded downpipes provide great increases in horsepower and torque on turbocharged vehicles by allowing exhaust gasses to flow easier as they leave the turbo. The high-quality exhaust manifold can improve the exhaust air flow rate and ensure you have a better driving experience.

What does a Downpipe do?

The downpipe exhaust on your turbocharged vehicle is directing the exhaust gases out of the turbine housing into the exhaust system. An aftermarket downpipe will typically be larger in diameter and either use a high-flowing catalytic converter or remove the catalytic converter altogether.

By removing the factory downpipe and replacing it with a high-flowing unit you are allowing the turbo to move gases away from the turbine which creates more power. Since the factory restrictions are now gone you can increase the boost on the vehicle as the factory downpipe is a choking point for performance.


1. Do downpipes add horsepower?
Yes. This downpipes nowadays have been shown to increase horsepower. An aftermarket downpipe with catalytic converters will add 10 to 20 horsepower on average, and that gain is noticeable anytime the turbo spools.

2. Will a downpipe make my car louder?
Yes. downpipes certainly will make a car louder with a more aggressive exhaust note. Flashark ones are louder than stock because they reduce the backpressure that occurs in restrictive exhaust pipes.

3. Will a downpipe void my warranty?
No worries. Installing an aftermarket downpipe doesn't void your vehicle's entire warranty. If you are a United States resident, then you're protected by the Magnuson Moss Warranty Act.
