I didn't mean to be rude.....I just thought he was being a smart a$$. I thought about going 2 1/2 in. pipe all the way back with a sho shop y-pipe and I thought the N1 in black finish would look really good, but I was not sure if they would fit. If you have pictures of your setup that would be great.Also what size pipe are you running back to your y-pipe? I really appreciate it and I am sorry about the rude reply.
