Next on the list was a fitment test for the Concept G Exhaust System. It's already an existing part for the Toyota Yaris, but this is the first time testing it on the 5-Door model. As you may know, the 5-door Yaris is slightly longer compared to the other models.

Nevertheless, the exhaust did fit. However, the muffler was too close to the rear bumper, and a revision will have to be made.

Next, it was time to install the Tanabe Sustec Pro S-0C Coilovers. The S-0C coilovers have the benefit of adjustable ride height while allowing proper suspension stroke and comfort.

This S-0C test was done with the coilovers set to the lowest ride height setting. A bit of driving revealed a comfortable ride despite the low ride height. It's a win-win situation! Next, we test the coilover at medium-tall height.

Before installing the front strut tower bar, the engine bay was inspected and measured. It's important to have the proper clearances.

The tower bar fit nicely in the engine compartment!

Mission accomplished. The tower bar aids in vehicle stability and it gives the chassis increased rigidity.

Next, it was time to test the fitment of the Concept G Exhaust on the 350Z HR. Fitment was a bit close to the rear bumper, and so it will be revised a bit for extra clearance. This will give good ground clearance while preventing toasty rear bumpers.

Other than the rear bumper clearance, the exhaust fit like a charm. Unfortunately, while this exhaust system on non-HR 350Zs recorded low decibels (within 93-95db), on the 350Z HR Model, the Concept G was about 100db.

Time to dyno the 350! Again, this dyno test was done with the Medalion Touring Exhaust as the only mod on the car.

The Medalion Touring Exhaust resulted in approximately +10hp and +10tq throughout the whole RPM range.
