Dynomax Super Turbo Mufflers have exclusive patented flow directors that channel exhaust flow and eliminate turbulence. They are made of all aluminized materials for sharper appearance and longer life. Dynomax Super Turbos feature large diameter internal tubes for maximum flow, fiberglass matting that delivers a mellow, true performance sound. Dynomax's Heavy Duty Super Turbos mufflers are arc welded for reduced high temperature fatigue and longer life. (All Dynomax Super Turbo mufflers flow in any direction unless stated).
Thrush turbos are aluminized for a long life and have expandable bushings for custom applications. There time proven spun locked heads have a leak free seal and all Thrush turbo mufflers are reversible for maximum flexibility.
IMCO Turbos are made of high quality aluminized steel for durability and lasting performance, they come in a variety of inlet and body sizes and inlet placements.
Turbopacks are quieter than a glasspack, for that "mellow sound". Great for foreign cars or vehicles with limited space but still want the turbo sound.
