SPDZ1 High Ground Clearance Long Tube Headers

Nissan 350Z • 370Z • Infiniti G35 • G37 • Q50 • VQ35DE / VQ35HR / VQ37VHR

Unlock the true potential of your VQ-powered Nissan or Infiniti with the SPDZ1 HGC (High Ground Clearance) Long Tube Headers. Engineered for enthusiasts who demand maximum performance without sacrificing drivability, these headers deliver noticeable horsepower gains, stronger mid-range torque, and an aggressive exhaust note that every VQ owner loves.

Unlike conventional long tube headers, the innovative High Ground Clearance (HGC) collector design tucks the collectors higher into the chassis, dramatically improving ground clearance while maintaining excellent exhaust flow. The stepped primary design helps preserve low and mid-range torque while still supporting impressive top-end power gains.

Manufactured from premium 304 brushed stainless steel with heavy-duty CNC-machined flanges, these headers are built to withstand years of abuse on both street and track.

Came based on a work buddies recommendation. I was late by 30 minutes, confused my appointment time. But, 10/10 would come back. Came for a Downpipe and midpipe install. Not only was the gentleman accommodating, He ran into some issues, staff helped me out and pointed me into the right direction and got me going! They got my business and wouldn’t go anywhere else again!

Absolutely love the customer service that you get with Speedzone Performance! All my questions are always answered in such a timely manner and this a big PLUS because I live out of Florida and for them to be on top of answering all my questions in such a way means a lot. Thank you all for the amazing customer service.

My favorite place to go for anything car related, they have anything you could imagine & more. The people who work here are the coolest and most helpful people I’ve yet to meet at a car shop. They also don’t try to force sales on you and they genuinely help you with what you’re looking for, 100/10 shop!
