Hey, I am looking to get a rear droid ii bar for my lancer but was wondering about the exhaust set up

obviously the rear doid bar caters for twin exhausts in the middle of it and was just curious to know if it is easy to have this done from the original exhaust and how much extra it would cost on top of the purchase of the bar itself

cheers

 

Go to Fibremotive to see some pictures but I am pretty sure there is some Lancers getting around with the exhuast going through the back. But it wouldn't be much. A 2" Stainless steel from the cat-back with a big resonator costed me $150 + it would look better coming through there

Cheers
