Listing says Brand New TOP SPEED PRO-1 Dual Catback Exhaust System in Polished Stainless Steel with TIG Welding with 100mm Tips / 60mm Piping - Under 97db sound level with Silencers (Silencers Included) / No C.A.R.B Exempt for California Customers.What does No C.A.R.B Exempt for California Customers mean? I live in California BTW lol
The pictured system does not include a catalytic converter. Unless a converter is located on the engine pipe (upstream of the long pipe shown) installing this exhaust system would eliminate the converter. Converters oxidize unburned hydrocarbons and convert CO to CO? thereby improving air quality. The pictured exhaust system would not meet emission standards in many other States as well. (CARB is California Air Resources Board). The pictured system will not improve engine performance, (the splitter is too far from the outlet) but will attract Police attention due to excess noise. If changing your exhaust note is the objective, you can simply replace the existing muffler. If this is unclear, update your question. Please choose a best answer from among those you get.
