These stainless steel three inch downpipes with catalytic converters are now available, they are unique as they bolt up to the factory cat back, 2.5", & 3" aftermarket exhausts allowing you to remove the bottleneck that these other "3inch" downpipes have. There is no need to have an exhaust shop cut and weld in the proper true 2.5 or 3"end that connects to the y pipe. This means you install full downs to your turbos once and only change the v band ends at the y pipe if you change your cat backs..if you also have a true 3" cat back, these downpipes are for you.
