Yeah, that should work if your sure the flows are 2.5". There are a few people who do that.

well if I rember right the hanger are welded to the stock muffers and the stock pipe is 2.25. so a reducer of some king may make the job go faster.

so you will need to deal with those two issues. I would proably try to move the hangers to the pipe unless you bought the stainless flows. the facotry exhaust is stainless so it will outlive the flows if they are alumized. If you bough stainless you can put the hangers either place.
