Question about ypipes Hey guys. I was just wonderin what you think about the mac pipes with high flow catts? I just ordered them earlier today and was wondering how well they'll perform. Thank you.
i dont know if the mac cats and mac "high" flow cats are the same but the mac cats dont flow worth ****. i assume you have the mac headers. macs with ory or some decent cats arent that bad.

no I have jba shorty headers and a borla cat back. I was thinkin the highflow macs should flow quite well because the site I ordered them from says they reduce factory restriction, so its better than factory I guess. My stock y pipes got a little bent from running over a deer 
if you can cancel your order. since your on shorties a new y pipe will net you close to nothing and the stock one flows quite well for what it is. only get a new Y pipe when going with mids/lt's or else is just a waste of money. gut your stock cats if you dont need to pass any emissions.
