yeah i have to agree,, if u go to dynomax they had a rebate on there ultra flows,, it ended up being 50bucks after a 25dollar rebate,, not bad,, then i had a magnaflow muffler out back and im happy with the performance,, if u get a magnaflow or flowmaster(str8 through muffler) and u dont have a res(mid muffler)u will get droone,, sounds great on WOT by sucks on low speeds and low Rpms,,
