These exhaust products are of premium quality and made to original factory specifications in the USA. All of Drake's products have been test fitted on the appropriate model prior to production to insure a trouble free installation. We use only the heaviest gauge aluminized tubing available. Mufflers have correct factory brackets when needed and are also aluminized to eliminate early rust out. All kits are compression bent just like originals for that concours look. H-Pipes and hanger kits are sold separately.
