Sonata, K5, Stinger and G70 2.5T High Flow Cat Downpipe (EPA Approved)

IMR has done it again. We designed a Primary Downpipe to help you make more power sooner. Our mandrel bend design and EPA approved High Flow Cat get the job done. This product, a secondary downpipe and exhaust have all been fabricated for and installed on our customer's car, David from Connecticut. He provided his car for the research and development and is enjoying the benefits. Dyno numbers will be available around the start of the new year. He now had the JB4 and HKS plugs which we also carry on the site. Downpipes have a 2-3 week lead time. 

Cost is driven by the EPA Approved cat. This is the only option we are offering.
