    I took my stock mufflers off after about 50k miles on my 2007 Pete w/ Accert Cat and put a set of cheap after market mufflers on and it made a big difference. Then after about 400k miles I bought a set of Pittsburg Power flow threw mufflers and it didn't make any difference.

    There is a material inside the mufflers for ACCERT Cats that is like the same thing in a catalytic converter. Get a cheap set of donaldson mufflers and you should see a difference.
