Dyno 3: GReddy EVO2 Stainless-steel Exhaust
Pros
You can always rely on GReddy to produce an exhaust that is both handsome and quiet. This mandrel-bent exhaust is smooth and has a mirror-polished finish. The offset canister hides most of the muffler under the bumper so you only see the exhaust tip. It has great clearance, especially on lowered cars. Very clean, sounds mean, plenty of bling. We made 112.9 hp and 97.5 lb-ft of torque. Fitment and finish are first class--pretty much everything you'd expect from a GReddy product is delivered. And it's street legal.
Cons
Nothing comes to mind.
Notes
We gained back some low-end torque and gained some mid- and high-end torque and horsepower. The exhaust breathes better than stock without sacrificing too much torque-giving backpressure. Again, the temperature increased, potentially robbing horsepower. Remember to use WD-40 on all of your hangers and bolts. The stock exhaust bolts were pretty rusty on this East Coast car.
