Our new lineup of complete 409S® stainless steel
American Thunder® exhaust systems for 1964-1972 Chevrolet Chevelles are designed
for the performance enthusiast who not only wants a great system that delivers durability
and muscle car tone, but a true bolt on component that increases engine horsepower
and torque. Backed by our 10-year limited warranty, the systems center around
the Super 40® performance mufflers and feature our high flow, mandrel bent 2.50
tubing. Whether you have just one classic Chevelle, or a whole fleet of them, Flowmaster
has you covered with the correct easy-to-install system for the job.
Ok I have a question I own a 71 Chevelle that I am currently building as a pro street. It has a narrowed 12 bolt that will be spinning 33x18.5 tires. Can this system work with my configuration ? Also is it available in a 3" as well ?
