FAQ

What's the difference between downpipe-back and turbo-back exhaust?
A downpipe-back replaces the exhaust from the downpipe rearward; a turbo-back also replaces the downpipe for the freest-flowing setup.

Aluminized or stainless steel?
Aluminized costs less and suits drier climates; stainless resists corrosion and lasts longer, especially where roads are salted.
