Stainless Steel Headers

Here's a perfect example of why Advanced Street Performance is your one stop shop for all your custom fabrication needs. This Honda Civic h/b from Stage2auto has had it's gas tank removed and replaced with a fuel cell inside the engine bay. ASP designed its custom stainless steel race header with megaphone/reverse cone and the aluminum exhaust to match this unique design.
