The 3" section before a small 2.25" cat-back would KILL exhaust gas velocity and create a huge area of high pressure in the downpipe.

thanks i was kind of thinking the same...but do you think it would be worth the money to basicly just have the cat and the ubend removed(pretty much what the out come is going to be)?? any power gains cuz if not im going to return it.... anybody else feel the same???? got the car up and cooling off so let me know!!! thanks!!!
