Ok i have a apexi N1...where i live i dont need cats so i took mine out..however its really loud...i dont want to put my cat back on cause i have a 3 in exhuast for my turbo...but i want something that will quit it down as much as i can without loseing HP>..

i say in summit they have a product from dynomax..its a 16 in muffler that it 4 in round with a inlet out let of 3 in so it will fit perfect on my exhuast pipeing...would this work???

thanks for the help
