I am running a 3" downpipe to a 2.5" exhaust do you think i will lose a lot of power in the setup since i am not running a cutout or a 3" all the way down?

 

If I was in your shoes, I would definately get a 3" exhaust set-up some time down the road. Check out http://www.kteller.com, I made mine with there mandrel bends! Awsome company

 

ya i was thinking about getting the kteller 3" piping kit and a vibrant exhaust but im short on money right now so i was wondering if a 2.5 will do me good until i get some extra money lol

 

it depends on what kind of power you are making and if you WG is open dump. I make 300 on a catted 2.5" with a chambered rear muffler and open dump. My down pipe is 3.5" until the cat. There are no signs of it choking up top.
