2.5 exhaust

I used the mufflers that came with system, I welded the two sections of exhaust pipes and used clamps on the mufflers and tail pipes,i will run it for a while to see it changes, it's not real bad just different, maybe later I'll try different mufflers,it's been raining so much here I can't drive it alot,I have hedmen elite header on my duster,what i found out while installing this system was that on the passanger side i had to cut down the lenght of the exhaust pipes to make them fit due to the lenght of the header on that side,
Thanks for the reples
