Our conversion kits combine high-quality SSI heat exchangers and Bursch free-flow exhaust systems for a straightforward bolt-on solution to your need for extra performance. The Bursch Steelpak free-flow exhaust system that comes with your conversion kit is individually hand-welded for precise fit and durability and matched to your SSI heat exchanger. Painted gloss black with chromed tip, the Bursch system produces a deep throaty exhaust note that says High Performance. Conversion kits include SSI exchangers and Bursch muffler, gaskets, nuts and bolts and engine oil lines (when applicable). Previously, conversions using direct replacement heat exchangers needed some modification. We've eliminated that problem! Our conversion heat exchangers are updated specifically for each application for easy installation.
