NASCAR SPRINT CUP Stainless Exhaust

These are some photos of a Stainless Exhaust System we built at Metalwoks!

This photo shows a 304 stainless steel intermediate pipe from a NASCAR Nextel Cup Super Speedway Car that I fabricated last year. The front ends of the tubes are expanded and slip on the header collectors. The center merges directly behind the transmission and the outlet end of the tubes have been “ ovalized” for ground clearance and connect to 1 1/2" thick fabricated tail pipes. The material choice is 304 Stainless Steel because of its durability in the extreme heat environment of stock car racing. Mild steel in this application is prone to overheating and cracking.

Internal and external views of the center merge.
