In this video, I take my GR86 from stock to a full exhaust upgrade, featuring the JDL Ultra Quiet unequal length header and combo pipe, paired with the AWE Tuning cat-back exhaust. I showcase before-and-after sound clips, in-cabin footage, cold starts, drive-bys, and highway runs. Stay tuned for future videos, where I'll dive into E85, a flex fuel kit, and a tune—giving full impressions of those upgrades!
