QTP HEADERS/Y-PIPE SALE!!! Quick installing question! QTP is on sale at fasttoys.com, and i'm ordering them. The only issue is, the headers have a 3" collector pipe. The y- pipe is also 3", will they fit my 2 1/2 inch Borla catback? I mean couldn't i just put an extension or something to make it fit, or do i just have to change the whole cat back system again?

On the Flowmaster Merge Collecter that sits before the I-pipe, it steps itself back down to a smaller size. I don't know what size it gets to exactly but it's smaller than the main thing. Call fasttoys.com and ask them.
