Replace your rusty, worn exhaust and enjoy OEM looks, sound and easy installation with this custom built system.
These systems are designed to bolt directly to stock mufflers or to our reproduction mufflers.
Restore durability and performance with aluminized or stainless steel exhaust.
We offer you several choices.
Which Exhaust Pipe Material is best for your Corvette and driving style?
Aluminized Pipes are quite durable and will generally last three times as long as the factory installed pipes.
409 Stainless Steel has additional Chromium and Nickel to resist corrosion. A magnet will stick to it, as it still has a high ferrous metal content. It is an economical upgrade to Aluminized pipe.
304 Stainless Steel is the Ultimate exhaust material. It has approximately 20% Chromium and 10% Nickel content. So much so that a magnet will not stick to 304 SS pipes. If your Corvette is driven where corrosive road chemicals are utilized, or if you intend to keep your car long term, then 304 SS is a wise and worthwhile investment.
