Custom Exhaust Mock-up and Expert Consultation

What happens here

The custom "boom tubes" exhaust system is introduced. The components are temporarily positioned under the car, and the creator realizes that modifications (such as extending pipe sections and precise X-pipe placement) are necessary for optimal fitment and sound. He calls "Dr. Gas Jr.", an exhaust specialist, for advice. The conversation covers key design principles: X-pipe placement near the collector for scavenging, the benefits of mild steel over stainless steel for certain applications (like flat boom tubes) due to its flexibility and reduced risk of stress cracks, and techniques for welding and fitting the pipes.

Goal: Design and plan the custom "boom tubes" exhaust system with expert guidance.
