Great fit and great performance

After reading many reviews and looking at dyno charts I clicked on this. My 07 G35 VQ35HR sedan already had air intakes, high-flow catalytic converters and a special 2.5" X-Pipe dual exhaust with 4 Magnaflow mufflers. With a heavy sedan and automatic, the car really needs more torque than horsepower. I saw a dynamometer. of them with the fact that they offer more than 20 ft/lb of torque gain in the low-mid range and an average of about 14 ft/lb. Resonance pipes of the same length and drain elbow. This car has never barked tires when shifting into 3rd gear at 60mph, but now it does! Welds look massive and durable. Thick flanges and plenty of clearance throughout. Installation took about 6 hours. my time. Have a new heater hose assembly coolant gasket and a pair of new hoses ready to connect the heater tube to the pipe. you will need them. I just changed the air conditioning compressor when the clutch recently failed. Removing the low pressure AC hose from the Mpressor AC hose and heater pipe really made the driver's side job easier. You will also need to remove the lower steering shaft. I screwed the manifolds onto the high flow coils and installed the new 02 sensors and then installed them as a unit. Headers and crampons are much easier to align and secure on a bench than in a car. A second pair of hands is really handy to align and place them. If I had a car on a lift, it would be faster. Otherwise, set up sturdy stands and raise the nose of the fountain in the air.

Pros
  • Exhaust and emissions
Cons
  • Negative gift
